The Soaring Diary

Mar 1999 to August 1999

(In chronological reverse order)

Wed, 11 August 1999.

This is the last entry for this volume of the Soaring Diary.

I have had a couple of good flights in my DG. Flew out to Mina, then up to the Tracy Power Plant and back to Minden. Another day I declared and flew a 500 K, but was 500 feet too low to make the last turnpoint, before returning to Minden. I tried again a week later, but didn't come as close. I have observed Mike, at High Country Soaring doing some really high speed runs down to Bishop and back - he seems to have that route figured out. I also observed Pete Williams fying down the Owens Valley and back to Minden. On his flight last week he AVERAGED 72 mph. Very impressive. On that same day I flew down to Lee Vining, and only stopped to turn in one thermal between Lee Vining and Minden. I wish I hadn't exhausted myself on the previous day's 500k attempt - otherwise I would have joined Pete on his long high speed flight.

Wed, 14 July 1999, 11 AM, last entry was almost 3 weeks ago.

Haven't heard from anyone about good flights. There were clouds over the tahoe area, and the weather looked unstable, so I checked the Soaring forecasts published by the NWS at Reno for the first few days of this week. Each day the soaring forecast called for thermals up to 18,000 ft, at strengths of over 1300 feet per minute. I'd say it was a good time to go soaring.

I had a phone message from Cindy that she went to fly at Parowan, so maybe we'll soon have some good soaring reports.

There was an article on page three of the S.F. Chronicle this morning. Here is what it said:

Head of Air Museum Killed in Glider Crash.

Minden, Nev. - Donald Engen, the head of the Smithsonian Institution's National Air and Space Museum, died yesterday when the glider he was in broke apart and crashed. He was 75.

Thurs, 24 Jun 1999, 8 AM, last entry was two weeks ago.

Haven't received any flight reports, except for the mini-Air Rallye that Shelton had at Cal City, but that was already posted on the PASCO page for us to read.

The tragic accident at the Nationals, with the tailplane falling off the glider before it was in the air was on national news. I'm sure we'll have an NTSB report later in the year. Whenever there is an accident, and you say that couldn't happen to me, you are just tempting fate. Always try to determine how you can prevent the same thing from happening to you.

The Board of Directors of the VSA (Valley Soaring Association) have been making some major decisions. The VSA newsletter - "The Windsock" will be forthcoming.

Thurs, 10 Jun 1999, 10 AM, last entry was a couple of weeks ago.

I've heard about two weekends of great flying at Truckee. 29 and 30 May were 500 k days, 31st was just about a 200 miles type of day. 5 June was also a 300 k day plus. I was up there on the 6th. Wave to 27,000 in the Minden wave window. I went up to 22,000 and back down to 17,500 headed south, turned bridgeport, turned south Lake Tahoe Airport, flew up the west coast of Lake tahoe at 15,000, then went north to turn sierraville, and back to truckee. Monday the 7th was a high wave day, but not as much instability.

Regionals were held at Montague. Results are on the SSA web page under contests.

Had one report this period. Armand flew out of Reid Hillview in his Cessna 150, landed at Cal City, launched there in an LS-3, and after a good flight, returned to Cal city and then back to San Jose in his Cessna - here is his story....

From: "Armand A. Medieros" Here is my wave-day flight report for 6-6-99: All distance in nautical miles. KRHV-L71    2.1 hours     Had nice tail winds the whole way down! Normally takes 2.6 hours Arrived L71, eat lunch, read LS-3 manual at least 5 times through. Cockpit Familiarization, preflight, get comfortable in it. Takeoff in LS-3, release at 3-sisters in pegged vario lift...lift fluctuates and dies, I slowly make my way back. Arrive back at L-71 4500 MSL (2000 AGL) and turned off the Cambridge vario system that was driving me nuts anyway! Find a tertiary Wave 1 mile NW of L71 abeam the runway 6 number. Slowly make my way back up to 8200' MSL. The wave starts to form better, I head W again towards boomer ridge and hit a secondary at 7000' about 6 miles out, climb in the secondary to 8400' and proceed towards the ridge again where I see a couple gliders working the lift. Get to the primary W off boomer ridge and work the lift. The wave is only a couple miles wide at this point, so fly min-sink and turn often. The lift shifts into sink again and I find much better lift further W past the ridge. This time I get a solid 8 knots up that lasts for miles. Worked the lift to 11,500' then found a very sweet spot. The sweet spot runs all the way past Kelso Valley Airport and ends just short of a peak of the W side of the valley. I make this run once ( Boomer Ridge-5nm NW Kelso Valley Airport) and top out at 13,400', my high point for the day, I make the run again at high speed to the end of the lift and spy some rotor to the SW. I head for the rotor in terrible pegged down sink about 7 miles away and connect in pegged up about 5nm SW Kelso Apt. Here I climb back up to 12, 600' or so and spy another roll cloud forming on the way to Tehachapi Apt. So now I run more or less a direct line from Keslo Valley Apt. to Tehachapi in alternating sink and lift...I just sort of porpoise along all the way. By the time I get near HW58, the rotor cloud has disappeared...they're forming and dying quickly today...the wind is fickle. I proceeded to the area where I thought the rotor was and find sink. By this time I'm down to about 11,000' so head back towards the three sisters. I find moderate lift along the way and heavy sink, but the LS-3 is a sweet bird and powers through this stuff. Arrived at Tehachapi Pass at 9000' or so and proceeded to run down the ridge again towards another rotor I saw form. I connect with this other rotor about 1 mile N or the windmills behind boomer ridge and climb to about 11,500' when the lift dies and the rotor evaporates. Made the run towards Kelso again in much lighter lift, just bumping along and then headed back towards the ridge. By this time, my knee was starting to hurt really bad because of the angle and lack of support in the LS-3. I think I need more butt pad so my knee can rest lower. In any case, I just sorta bumped back towards L-71, all the while watching other power planes and gliders having a good time. I bumped around the airport and "circled" in very narrow lift for a while then followed another GROB around for few minutes fun then landed. There was lift everywhere, even over the airtport 6-knots up could be found. It seem to me that I had been flying a couple of hours at the most...turns out my flight time was 3:19! Anyway, we put the LS-3 to bed and I loaded up the o'l Cessna 152 for the trip back. I took off from L-71 and climbed to 7500' (5K agl) in 6 minutes! A record for me! Then I headed into the dreaded Tehachapi Pass and got down to about 6500' near Tehachapi Airport where the cars were passing me! Jeez....I stayed at 6500' because that was my return trip altitude anyway, ground speed went as low as 58 knots in the sinky parts... Anyway, as it turns out, once I got to the inland valley, the wind was only about 330 @ 15 knots! Good news! Then, when I got past Delano, the head wind dropped to about 320 @ 10 knots and going slowly lower! By the time I passed Lemore, the head wind dropped had dropped to about 5-7 knots! Hurray! I didn't have to land and refuel! Total air time L71-KRHV 2.8 hours! What a hell of a good day I had...complete with minor sunburned face! 8.5 total log time Cessna and Glider..... Armand ---------------------------------------------------

 I haven't heard who won the Doc Mayes award for 1999.  Elden tells me that John Volkober won the Peterson Trophy.  His exact words were:
"John Volkber had the longest handicapped flight of 245/230 for the Chico Distance camp of the flights that was turned in. This Distance Camp had the longest flights that we have had in years."

Gary Kemp has continued to have excellent flights out of Williams - here is the  latest flight report he sent to me:

Well, your record is still safe.  I flew 361.5 miles today on a mediocre day, the lift averaged 3.2 kts.  I took off at 11:45 and released, in the valley at 3500 feet.  flew south on the first ridge and it took me an hour to get high enough to go to Walker ridge.  Then to Goat Mt., Gravelly Valley, Round Valley, T-15, Hayfork and return to Hiway 16/20 and then over to Pearce, Sites and Colusa. Got to just over 10,000 feet.   I think some have moved to Truckee too early.  6 flights since April 24, averaged 285 miles with the 6th being only 130 miles.
-----------------------------------------------------------------

I have the flight traces, and permission to show them from both Volkber and Kemp for the above flights, but don't have the time to display them - sorry.  I might get to them next week.

I sent out a message to all on the pilot email list.  If you want to be on the list, send me your address- here is what the latest msg said:

Hi there,
I was just browsing through your website and thought you might be able
to help me out. I'm with a television program called Storm Warning on
the Discovery Channel. We're based out of Vancouver, Canada. We're
currently looking into doing a segment on an incident involving a glider
in the U.K. that was struck by lightning, forcing its two occupants to
parachute to safety. In order to effectively tell their amazing story,
we need to find some footage of gliders flying near thunderclouds, shot
either from the ground or from the plane. If you are aware of anyone in
possession of this kind of footage, I'd appreciate hearing back from
you.
Thank you for your help,
Douglas Quan

2.  Recent flights - I have placed all of the info I have received about recent flights on the diary page.  Be sure to read of the long flights that NK has been accomplishing - also on the diary page.  Don't have a full report on the Chico Distance Camp, or the Doc Mayes Trophy Results, but I did receive this from Elden -
-------------------------
John Volkber had the longest handicapped flight of 245/230 for the Chico Distance Camp of the flights that was turned in. This Distance Camp had the longest flights that we have had in years.

Wed, 19 May 1999, 8 AM, last entry was a this past Sunday.

Cold front went thru last nite. Hi temps today are maybe 80 to 81 in Sacto Vly.

24 and 48 hr pressure charts (dashed lines on the VSA link) show strong winds from the south on friday - if the pressure fcst is accurate.

Oakland sounding (at 5 AM today) shows decent thermals - but very dry air - probably no cu. That makes it tough. big wind shift in direction between 6 and 7,000 and then back again. That'll make it hard to track the thermals in the climb. But reading the adiabats, if temp gets to 27C/81F then lift will get to 7 or 8,000 if the wind doesn't blow too much, and up on the Mendicinos, if the temp on the side of some of those hills gets up to 81 at 3,000, then that column of hot air will rise to over 15,000. (but 75 would be more the tmp expected at 3,000 - which would yield thermals solidly to 10,000, with slow climbs to 15 in the max heat of the day.)

It could be / probably will be a good day. I plan to fly from Nut Tree today. I hope someone else will be in the air.

ALSO - the National weather Service - Reno office did not have the normal format for the soaring fcst displayed. Are they changing it? Dropping the old format? Maybe they don't know how much we all look at that page, and feel no one cares. If you check the Reno Soaring Fcst, and it isn't posted - you ought to email the Reno office and tell them you'd like to have that product displayed! It will be a great loss to all of us if they stop running the soaring fcst!

Sun, 16 May 1999, 11PM, last entry was a week ago.

Heard yesterday (saturday the 15th) was a good day. Received a report from Gary K. - That report follows. We also received a report from Chris about a Radio for sale. That report follows Gary's report. The conditions that existed yesterday were special. We need to be ready to take advantage of such conditions. Before summer gets here, there will be days like this (yesterday). Lift without overdevelopment! It's easy to set records on days like that, but the trick is to be there. Perserverance - that's part of it. Dedication to the sport. Will to achieve! All of those things. We do it because it is fun. I wish I had been there. Here is Gary's and then Chris' reports:

Peter, as theysay, you should have been here yesterday.  I took off at 11:45, took a 3500' tow to 3 sisters and worked south along the first ridge, eventually getting to 6000 feet, to the gold mines, good thermal, Crazy creek, Cloud bases about 8000, Calistoga, near Lampson, back to Crazy Creek, Gold mines, Walker Ridge and the North without thermalling, to peak 8069, then about 20 north to highway 36 and return to peak 8069, to 11,300 and without turning back to the gold mines.  Cloud bases,mostly around 9500' , averaged 67.5 mph.  If I had known the all - time distance record was yours at 371 I would have done that, another 100 miles was very doable. Walt Cannon flew North also along with others, PS, 5K....quite a few folks at Crazy Crek.  Walt commented that when you have 9000 feet over the Mendocinos, you are mountain flying and you have 9000 feet.  Not like at Minden.  He also wanted to know if it was always like this (His second flight on the Mendocinos).  I responded, "Of Course".

Mon, 10 May 1999, 8 AM, last entry was a week ago yesterday.

Well, this was the big weekend at Williams for this spring. It was the Chico Distance Camp, with participants competing to see who would get their name on the Lee Peterson Trophy (longest single flight), as well as the Doc Mayes Contest, which is now the best cumulative distance over the three day period. It was also Mother's day weekend, and that tends to put a crimp in the level of participation. I am doing this report because I had two different people tell me they appreciate these summaries of what's been happening. That bit of acknowledgement has motivated me to write this report.

On all three days, the wind was howling from the North. The weather this year has been a challenge (or stated another way - it really sucks). There was a pressure gradient near the surface causing the strong winds due to the high trying to come in from the Northwest, and the low not moving any further to the south east - result: winds from the North! As you went aloft they changed, backing (that means from a more counter-clockwise direction) - as I said, backing from North on the surface to northwest at 5,000 and west at 10,000. they were only 10 knots or so aloft, but the surface wind was more like 15 kts most every morning. You could see the pressure pattern and winds clearly on the pressure charts on the VSA weather pages. the sounding indicated we could get convective lift in the areas where the wind was blocked by mountains, and also later each afternoon when the wind settled down (only to start blowing again the next AM).

On Friday, I wasn't there, but I heard that several people had good flights - with JJ winning that day with some 200 miles or so, Jim D in his new 20 did well, as did five or six others.

Saturday was the biggest crowd. JJ flew again, as did Jim D, but others were going to have good days also. As I said, there were two trophies at stake here - one for the longest single flight, and one for the most miles in the three days. Unfortunately, not everyone had the rules straight. Ten miles between turnpoints seemed to be understood, but the rule that says you can't go immediately back to a turnpont which you just used, without an intervening TP was just too difficult for some pilots to grasp immediately, but they finally did!

There were a bunch of us that flew on Sunday as well, and John V was intent. I suspect he might have won the Peterson trophy, and maybe even the Doc Mayes Trophy. Jim D and JJ each had a shot at the Doc Mayes, but neither flew on Sunday due to other reasons.

The BBQ on Saturday night was more like "the Hinkle family BBQ" rather than the Chico Soaring Club. Elden's entire family turned out to bake the rolls, cook the steaks, make the pasta salad, logistics of drinks, plates, and grill all attended to by Elden and his family. And of course deserts. Midge contributed by cooking up some brownies and served ice cream and syrup as well. It was all delicious and lots of fun. I sure enjoyed talking to the people there. Unfortunatley, I was dead tired, and by Sunday night, I was really wiped out. With everyone flying over 5 hour flights we were all pretty tired.

On Sunday it was blowing even harder than sat in the AM, and but it let up around mid-afternnon, or so I was told. I spent the day up on top of the hills, flying another five hour flight, racing up and down the mountians trying to log the miles. Lift went up to 12,000 on both sat and sunday - but that was only at the very end of the peak part of each day. 10,000 was more the norm for the top of the thermals. On Sunday even Nevada Fox and Joe Findley showed up.
---------------------------------------------------

Sun., 2 May 99,  Last entry was Friday

Sat 1 May was a good day at Williams. Walt Cannon flew his first Williams cross-country, and was impressed with the lift, and the good speed and distances possible. He followed Dave Greenhill for awhile, but Dave continued North to Weaverville - that's on the Klammath Sectioal, so Walt may not have had that chart, besides I know he didn't have the latest GPS database for the Williams area.  In any case Walt didn't want to get more than 80 miles from home, so he quit following Dave.  I was heading north when Dave was heading south abeam Red Bluff. The two of us flew south to Alder Springs where we joined with Sergio. Then Sergio and I headed SE to Colusa, flew into the shear at about 2,000 ft, climbed back up to 6,000, and flew east and south, doing final glides back to WSC. Dave didn't have such luck - After going North along the mountains, he headed East into the valley north of Willows, and ended up landing there and needing an aerotow home.

Gary Kemp flew another fantastic flight - only his second one in his new Nimbus. He cruised up the Mendicinos from Alder Springs, and as he passed Anthony, he was up to over 10,000 in wave. Seeing the cu on the east side of the valley some 50 miles away, he decided to go for it. He crossed Red Bluff at 8,000 went east of Chico and eventually made his way back home, approaching Williams from the Northeast.
 

Sumner launched late, but I didn't get a report. Harolyn launched just 30 minutes after me, flew for a couple of hours between 3 Sisters and Colusa, reporting the locaton of the sheer line to those of us that were interested. Henryick had another good flight in the Libelle, doing a final glide from 6,000 north east of Colusa.
---------------------------------------------------

Fri., 30 Apr 99, 8 AM. Last entry was 1 PM yesterday

I made another attempt at putting a flight on top of the sectional.

Looking at Jet and pressure chart forecasts (from the quick list VSA wx page), it doesn't look all that good for today and tomorrow.  The low over Nevada/Arizona/Colorado is not moving to the east as quickly as was forecast earlier in the week.  The TV wx guys on 10 and 13 forecst the Sacramento temp to be in the low 80's today, with less wind than yesterday.  But I think they are just hesitant to admit to the public that it will still be windy from the north again today - but the pressure charts might be off.  I think I'll go try flying anyway.

---------------------------------------------------

Thurs., 29 Apr 99, 1 PM. Last entry was last yesterday

Wx looks hopeful for this weekend-   the jet is moving - finally!  The jet traveling down the coast will drop off, and the tail of it will take that low pressure off to the east, so we ought to lose the strong pressure gradients that are giving us all this wind.  And worst of all it is a north wind.  Hopefully there will be a cold air mass moving through as the wind dies, and with the expected solar heating, sans wind, we ought to have good soaring Friday PM or at least on Sat.  High clouds are expected late Sat, so try to launch early on Sat. if the heating allows it, as the soaring might end early in the evening.

I have been trying for many months to get a flight track ontop of a sectional, so we can view peoples flights in relation to the charts.  Here is an example of my progress thus far.   (Gary's track is not shown).  You can see that the overlay is not quite the same size as the sectional, and I will have to clean up which TP's are displayed, so that the image is easier to read, but I can't control all of the clutter on the sectional - only the clutter that comes in with the flight track out of the Cambridge display.

---------------------------------------------------

Wed., 28 Apr 99, 1 PM. Last entry was yesterday at 6 AM.

Kenny send us a report about Monday's flying - I'll put it at the end of this entry.

Yesterday morning I was deceived by the sounding chart.  The Air mass was slightly different.  I loaded with water, declared my 500k, and after I revised that bad database and reloaded the GPS, I launched.  I never got above 8,000 but did have a good flight.  Went pretty far, found consistent lift, been to places I have never been before, and remapped some of the TP's.  I won't bore you with the flight trace.

I spent many hours re writing the turnpont data web pages.  I would appreciate your coments on the philosophy stated regards to the purpose of and the election of turnpoints.
Also, I corrected the Williams data base again, and reloaded it - calling this one WSC428.DAT, which is file name shorthand  for "Willliams Soaring Center 4/24/99. Database

Go to the VSA home page and then to the turnpoint page to see the info.

Soaring Weather Outlook is promising for thurs or fri, or at least the weekend.  This is the time of year for prime soaring conditions in the valley. I think we'll have a good crowd at Williams since there aren't other events scheduled (that I know about), and Truckee isn't quite started up yet, and people are keeping their birds in the valley rather than the mountains because of the upcoming contests.

Here's Kenny's note about Monday's flying.

Hey Pete. 
     Just a note about today's soaring. Around
10:30, the sky was
completly 
obscured except for the NW which was littered with lenticulars over
Snow 
Mountain.  Winds on the ground were SE at 15, gusting to 25 and
obviously, 
winds aloft were westerly.  I took a tow with a student at 11:15
and 
contacted wave over Three Sisters and climbed quickly to 8000' and
proceeded 
to Walker Ridge where we found the primary.  We landed soon after
and I sent 
him (Dave McKay) back up solo.  He proceeded to find the wave and
climb to 
14000' which he was still climbing at 500ft a minute.  While this was
taking 
place, the Maxwell sheer was moving through the area and there were
climb 
rates in excess of 1000' per minute in the sheer.  Not a bad
day.  Hope to 
see you up here soon.

Went soaring at Williams on Sat the 24th, as did lots of others.  I was there early, but JJ already had his ASH-25 ready to go.  He and John were going flying.  Gimmey showed up just after Volkober.  Key was one of the last ones to arrive, flying in with family in his 182.  Sergio, Mike Schuster, and several others were ready to go well before me.  Joe Findley rigged George Marinos' Pegasus and loaded it with water.  I think he's practicing for the nats.  Gary Kemp was flying his new Nimbus for the first time, and what a flight he had- nearly 300 miles (WSC to Walker to Mysterious Vly to Calistoga to Walker to Anthony Pk to Yolla hill 8092, back down to Mysterious Vly, then over to Williams).  He was pleased with his flight and his new ship.  He was the only one of the big boys with a working GPS, as JJ, Gimmey and others were asking him for winds, and distances periodically.  I collected the flight logs of several of the pilots, but didn't have the time to depict them here for you, in fact I need to get over to the weather pages and see if today is going to be any good - we had a change in the air mass again yesterday.  Much colder today, but breezy West  winds are forecast by the TV news.  Let me mention a few other things, then I need to get going.

There were lots of other flights and good ones too.  Henryick flew the Libelle and Kenny did lots of training, rides and a few acro flights - or were those on Sunday? In any case, Williams did nearly 30 tows on Saturday - more than are done at a contest.  It was good to see such a good crowd out flying.  Many of us went to Dinner later, Mike and Diana arrived late - Mike took a flight, and then the two joined us for dinner, and I hear they are heading over to Europe.  I missed hearing about that bit of news while they were at dinner!  Sorry, no details.  I stayed overnite in the bunk room as did Key.  We had breakfast in the AM at Denny's, with JJ and Pat joining us.  That was a nice event also.  JJ is negotiating his 1999 soaring schedule with the chariman, so he was taking her to Calistoga Spas to encourage a positive attitude. Sort of a sales day for JJ.  I'm sure they both had a good day.  Sunday's flying started very late, as there were low clouds from the intruding marine air. But by 3 PM, you could go anywhere in the valley, but not over 3 or 4,000 ft. and there were no clouds, only dust devils to guide you, and the hills never worked all day.

All in all it was a fabulous soaring weekend.  George T, came by late on sunday as did Lucky Lady - Karol H.  Georege had his bird in the shop.  Karol flew dual in the Discus  Several of us had Pizza at the house with Rex and Noelle and family.

I reviewed some of the TP's being used by Mike Schuster and  Gary Kemp.  Key and I checked many against my list and the charts.  I revised the latest TP list for Williams yesterday.  I'll post it on the VSA TP page so you can use it if you want to. I have called this version - WSC426.DAT that is my way to remember that it is the turnpoint data for Williams Soaring center, and it was last revised on 4/26/99.

............

I just watched the TV weather - it looks like today ought to be a 500 k day - I gotta get ready to drive to the glider port.  If you miss today, be sure to watch for this thurs, fri, and sat, I think we are goind to have a couple of 500 k days in the area.  I plan to fly from Willimas up until the Maother's day weekend - big contest weekend at WSC.

Wind is blowing again today, but it is looking good for the weekend.  I plan to send out a message to all pilots saying the following:

1. Most importantly, I wanted to mention the changes forecast in the weather for this weekend.  From the forecast Jet Stream and pressure charts I just looked at, and looking at the Oakland sounding from this morning, and considering the flow aloft is fcst to be from West to East by sunday, we are in for a good day, if,  and whenever,  the wind stops, and the flow changes to light westerlies.  It could be late tomorrow or on Sunday.  I plan to be ready both days.  Thought I would share my optimism with you, just in case you haven't had a chance to evaluate the weather charts today.

2.  Activities reminders -
PASCO Spring Soaring Clinic is this weekend at Byron.
The Chico Distance Camp is coming up - 7, 8, and 9 May at Williams.
The Doc Mayes Fun Contest is also that same time, and the winner is now recognized by the Doc Mayes Trophy Award.  It is now based upon the distance only.  Whoever logs the most cumulative/total miles while flying from Williams during the three day period - 7, 8, and 9 May - using the Chico Distance Camp/ Peterson Award Criteria and rules, wins the Doc Mayes Trophy Award.  (The Peterson is for the longest single flight during that 3 day period).
The Avenal Contest is May 13- 16, and
The PASCO League Meet is at Crazy Creek 15, 16 and 22, 23 May.

3. One final note - I have been working on the Turnpoints at both Williams and Truckee.  Visit the VSA web page for further info on that subject.

The weather continues to be miserable - soaring is non-existent.  Tomorrow the pressure lines are close together at both the surface and at 18,000 and the resulting strong wind will be from the northeast.  However, the weekend does look promising- less wind and higher temps.  We'll probably have to take mountain tows, but that's all right. Of course all of that assumes the weather charts are correct.  They certainly have been full of erroneous info lately.  The forecast position of the jet and the forecast pressure charts haven't even been close to what subsequently transpires.

There have been updates to the turnpoint pages.  Truckee has been added.

Just had to check to see if it was any good today. Looking at the OAK sounding for 5 pm this afternoon, I can see I was correct in my prog. That inversion at 6,000 prevented even the warm air in the valley from ascending the Mendicinos. Glad I didn't waste my time driving to the gliderport. I have to work this weekend, but the outlook doesn't look good anyway. The jet is snaking up the coast, and after 48 hrs, there is a stronger jet out in the Pacific doing another U-turn to the north. I figure it can only get better! I plan to do a 500 k here in the valley at the end of next week. Anybody care to join me? I've laid out the turnpoints on the planned 500 k section of the Williams Turnpoint web page. Drop me an email if you might make it.

Miserable Wx! Yesterday it blew all day from the north. I reinstalled my Cambridge S- Nav since repairs were made, and watched Ron and son Chris work on their Pegasus. Paula fixed us lunch. Today I'm not even going out to the Gliderport. Based on the Oakland sounding, it would have to get up into the 90's to be any good, and we know that's not going to happen.

I'm looking fwd to the reports of the Geezer Glide. I think they might have had a couple of good days, in spite of the terrible weather. We'll wait an see.

Today I updated the VSA Home page and included info about the altitude chamber. The address that was in the Feb. West Wind was not complete, so you can see and go to the correct address on our home pages.

I also updated the Turnpoint pages. I think you will find the latest version of the Williams turnpoints more useful. However, due to the weather, I still haven't test flown those turnpoints.

Heard yesterday was good in the PM at WSC - maybe we'll hear from Joe Finley- he's flying today.  I hope to go tomorrow.

I heard Rex is changing the format of the Doc Mayes Memorial spring contest at WSC to something compatible with the Chico Distance Camp/ Peterson Trophy.  His proposals sound very promising and will undoubtedly be well received.  Stay tuned.  Be sure to plan on attending the combined event on May 7, 8, and 9.  I'll have the latest version of the GPS data base for Williams posted well before then.

Rex is also proposing a change to the PASCO Capture Trophy.  Another positive change.  We'll see what the PASCO board does with that proposal.  It needs needs revision - so that Avenal, Byron, Truckee, Minden and Air Sailing can be involved.  His ideas on that subject also sound very promising.  Again, Stay Tuned!

I just received the updates on my Cambridge L-Nav/ S-Nav.  Dave Ellis has written a good explanation of how it now works.  Be sure to get your update, and be sure to read the document written by Ellis dated Feb. 99 "Flying with L-Nav Version 5.7, etc."  It's the best documentation I've seen yet on the cambridge computers.

Went gliding yesterday.  Arrived plenty early, but fiddled around as usual and launched two hours later than I should have.  Kenny told me he had a good flight on Tue. in the Pegasus over to St. Helena, Indian Ranch and return - no GPS on board, so no images to share.  If one of you has a good flight, and would like to share the image of the trace, then capture/copy  it in the buffer (alt+prnt screen) and then paste it into a photo image program of some kind and then save it as a .jpg

After I finally got ready to fly yesterday, I talked to Mark and told him I'd be extending my engine at 1,000 ft and starting it on tow, and then shutting it down again at 2,000 ft.  The purpose was to see if it would show up on the Cambridge flight trace ok, which it did! Here is the vertical trace from takeoff to release from tow.  Now when I attempt my 500 k, I will use this as a means of validating that the motor was not used after release from tow. The green is climbing, blue is descending, and red is when the motor is running.

There is a new sod runway just behind (about 1/2 mile northwest of) the Three Sisters turnpoint.  You can see by my flight trace ground track that I almost used it .  Lift was good near the Indian Vly Reservoir (up to 8,000), and I had two low points which you can see on the vertical display.  One when within gliding range of Pope and the other near Guinda - there is a sod runway 1/2 mile northwest of Guinda that I was going to use, but then the wave began to work.  Kenny was reporting 20 to 30 knot winds from the SSE at WSC. On the glide from Capay to Williams I had at least a 30 knot tailwind!  It was turbulent on descent between 1200 and 800 ft as the wind changed direction by nearly over 100 degrees!

I waited over an hour before derigging, but the wind was still blowing at 10 to 15 kts. I had help from Kenny, Steve and Robert- thanks guys for making it safe.

It was a good flight, covering less than 100 miles, but it was good experience on reading clouds and seeing major surface wind shifts in each different area of the flight

Weather looks poor for today, tomorrow (Friday) looks to be very unstable, with more precip coming in on Sat-  two days ago the fcst looked good for sat, but not so any more.  Sunday may still be a rainy day and Monday looks good at the moment, but things change.  Watch the jet stream - see how the area to the east of us has changed in the last 48 hours from south to north over to a west to east flow pattern.  These storms are now passing through more quickly now that the jet has straightened out.

Regarding Turnpoint flies. I spent lots more time revising the set that I had been using. I've made a major revision in the one that was on the TP Web page. I will call it revision version number 3 (WSCv3). Some TP's are still off. e.g. Yesterday I could see that Indian Vly Reservoir Dam was way off, as were some of the others. It is apparent that the coordinates are from the old turnpoint book when we used to use photos - What we need now are the coordinates of the landmark itself (the old photo target - in this case the dam). I wish some of you would send me the data files you use in your Cambridge datalogger for areas such as Byron, Avenal, Cal City, Truckee and Minden, so I can put them on the TP web pages for others (and myself) to use.

Tough to decide. Fly today with north wind, showers, or wait till tomorrow with more of a nw flow on the surface, but rain approaching in mid afternoon. This next weekend looks much better, but these next couple are are my days off. Rats.

I spent lots of time redoing the diary pages, let me know if the latest stored volume (ending mar 99) is unreadable.

I spent time making up a bunch of 500 k flights out of Williams. I hope to post them to the turnpoints pages before too long. I need to get my 500 k diamond leg, and I hope to get it the last week of April flying from Williams. Anyone else going to be around that last week in April to fly from Williams?

The PASCO Spring Clinic is set up for the weekend of 22, 23 April at Byron, hosted by NCSA, contact person is Bruce Roberts at brucer@rockie.nsc.com and, the Geezer Glide (Western Seniors Compet) is starting this next weekend at Phoenix (11 - 17th) contact is Ray Gimmey at rgimmey@pacbell.net

I missed all of the action the last few days - had to go to work but I did receive a report from Gary Kemp, which I'll share with you in a moment. I saw a glider on the Vaca Ridge near the towers at around 2:30 this afternoon. I wonder who that was?

We received a flyer from Elden H. about the Chico Distance Camp. Click here to see a graphic flyer sent in by Elden which provides all the details. The essence of it is that the Chico Distance Camp will be held on 7, 8 and 9 May, Steak BBQ and Slide show at $12 per person.

Here is the article we received from Gary K. Thank you Gary for a well written article. I enjoyed reading it, and I'm sure others will enjoy it as well. Click here to see a Photo of Gary Here's Gary's article:

And the Wind Did Blow
by
Gary Kemp

Today was the first day of the Air Rally at Williams, Friday April 2. John Volkober in 13 took the first tow to the ridge and stayed local in week lift for about 2 and 1/2 hours. I released near Williams at 2100 feet and stayed local for about 2 hours, wind was blowing at about 17 mph.  John Shelton, was tired from a late night retrieve to Arvin and decided to take a nap.

We discussed the weather and I mentioned that blowing wind did not always indicate a poor day, but it had to blow after a frontal passage.  According to the progs we thought that tomorrow would be more stable but that there might be lift in the mountains.

The next morning, Saturday, April 3, I looked outside as I awoke and saw an overcast sky with the wind blowing briskly. This was at 6:00 AM. As I puttered around getting ready to go to Williams (27 miles south for me) I could see the cloud cover dissipating from the North and heard on the radio that the Weather Service had issued a high wind warning, great, but my ship was together from yesterday so off to Williams I went.  On the drive down I could see what looked like cumulus clouds beginning to form over the mountains and in the Valley to the North (about 9:00 AM).

There was John Shelton and I at Williams when I got there and as we stood around watching the wind gusting to 35 mph we could see a line of cu forming over the first ridge to the west.  Kenny said he would give me a tow.  I loaded up my gear and pushed out with a great deal of help.  Shelton mentioned I was making glider pilots look nuts by flying.  I launched at 10:45.  A young man ran my wing and it felt as if he held on to it (my first inclination was to do without a wing runner, but he seemed to want to so I let him).  Anyway, I soon found myself heading for the hanger and as I reached for the release, Kenny and the wind combined to pop me off the ground and apparently was airborne and blown sideways over some trailers sitting there.  It looked a lot worse that it was I think but sufficient to discourage others from flying.

We climbed rapidly through very turbulent air and it smoothed out about 2500 feet, I released just before the three sisters at 4000 feet and found turbulent, disorganized lift that I was able to work to about 6500 feet.  At this point I headed towards the North end of Walker Ridge where there is often a convergence working and where there was a line of cu.  I didn't find anything and had to scamper back to the valley encountering a lot of sink I just cleared the ridge at 2500 feet.  I again contacted lift that got me back up and I headed towards Indian Ranch.  Coming out of Indian Ranch I contacted very good lift that eventually averaged 1100 feet a minute and took me to 11,000 feet which was cloud base.  I worked between 7 and 10 thousand feet most of the day.  I flew to Willows and then Corning averaging about 25 mph.  I did find lift as strong a couple of more times, once even bouncing to 1500 fpm.  It was very cold as I turned south and made the Sutter Buttes in about 15 minutes before returning to Williams.  Bob Klemmedson was there wanting to fly the Duo, but the towplane wouldn't start.

The flight was 5 hours and 10 minutes and could have been longer.

As to the weather, the only thing I can think of is that we had a frontal passage which brought in very cold and unstable air.  I have run south to near Bakersfield in these conditions but caught the front and was not able to proceed further.  I think the same would have happened today.  It would be interesting to know.

Remember, just because the wind is blowing doesn't mean that it won't be good.  I flew for 5 + hours and 140 miles and experienced the some of the strongest lift and highest cloud bases that I have ever had in 20 years of Valley soaring.
