Saturday, November 9, 2013 Goodyear Blimp visits Avenal!

WEATHER
Visibility:  Somewhat hazy, but good VFR
Wind: 10 kts out of the South early, lighter but still out of the South later.
Altitudes: 4000ft AGL off of tow.
Time Aloft: One hour.
Max Lift: 100 fpm
Temperature: 78 deg. F.
Comment:
Tow pilot: Bill Vrastil from Santa Ynez in the 235hp Pawnee (Spectacular!)

How many of you are familiar with 14 CFR 91.113(d)(2) (aircraft of different category on converging course, glider vs. airship)   or ever thought you would have an opportunity or the need to test it?  I thought I had seen a lot of things  after over 40 years of flying gliders, but I was mistaken, when today the GOODYEAR BLIMP flew past the Avenal airport just as we were getting ready to launch!   The wind was out of the south,  and the blimp was traveling in a southerly direction. Probably it was trying to stay low and somewhat in the lee of the coastal mountains in order to stay in lighter headwinds, it was traveling South parallel to, and just over the Kreyenhagen hills to the West of the airport at an altitude just below 3000ft MSL. As the blimp slowly approached, several gliders were qued up waiting to launch.   At the head of the grid was Jan Zanutto, the first to take off. We though we'd all be able to get in the air and get a chance to see and photograph the blimp from our gliders, but it was making remarkably good progress to the South against the headwind, and Jan was the only one who was close enough to it to get a photo from the air before it disappeared in the haze to the South.  Jim Rickey got a couple of shots of it from the ground.



We are going to have to add a new "scenario" to our FAA scenario based syllabus.  "Lets say you were ridge soaring,  going south by Tar Canyon. You decide to make a 180 deg. turn to the left to reverse direction on the ridge. The next thing you notice is your windscreen is full of the front end of the rapidly approaching Goodyear Blimp!. You are sandwiched between the ridge on the left and the blimp on the right. Quick, what are your options?". Before, I would have laughed at the possibility of that scenario ever occurring. After today's visit from said Goodyear Blimp..... Well, I'm still laughing!  Anyway, the possibility is no longer zero.












We were very glad to have Harold back in action today. He is over his knee surgery two weeks ago. He was doing fine getting in and out of the back seat of the 2-33.

Martin Caskey had 3 flights in preparation for his commercial glider add-on rating which he is working on prior to getting his 15 meter Nugget sailplane back in the air soon. He practiced the Practical Test Standards maneuvers including stalls, flight at minimal controllable airspeed, steep 720 deg. turns to a heading at a 45 deg. bank, accuracy landings, landing with no spoilers using a slip for glider path control,  and landing without reference to the altimeter. He also boxed the wake and did a 200 ft. simulated rope break.


Andy Reisteter and Steve Schery both flew their Russias and were able to sustain for a period of time. The lift was not very good, but we did have a few dust devils at the peak time of the day.

Dan Clark was out early flying with Dan Gudgel in the Orange Crush and stuck around all day helping to run wings and hook up towlines.

Jim Rickey was out working on his commercial glider add-on rating and practiced boxing the wake, flight at minimum controllable airspeed, stalls, 720 deg. steep turns, slips to a landing without use of spoilers, accuracy landings. He also pulled duty cooking hamburgers for lunch and helped everybody else with dragging gliders around, running wings and fueling the tow plane.

 Jeff Richardson was out and flew the 1-26.

We had the Pawnee tow plane  from Santa Ynez flown by Bill Vrastil,   which provided spectacular tow performance.  At one point in the morning, we had a Southerly tailwind, but were still able to operate off runway 31, with the gliders landing on 31 and stopping just short of the club house, then taking off from there. In spite of the downwind takeoff and the displaced take off point, the Pawnee was breaking ground just slightly past the tow plane hangar, and was already at about 200 - 300ft AGL by the end of the runway!  Members helped Bill refuel the Pawnee before he departed for Santa Ynez at the end of the flying day. He holds 42 gallons total,  and was down to about 12 gallons at the last top off before departing.

Mike McClellan, who has been a member in years past returned today and rejoined the club. He got his BFR completed with Harold.  We are very glad to see Mike back with us. He has been a great asset to the club in the past. He single handedly poured the footings for the hangar we were going to have before it was sadly destroyed in a windstorm a few years ago.  He also was expert at ridge soaring the Blanik and was known for flying it over to Harris Ranch, landing for lunch,  and then having Loyal tow him back while he digested his Harris Ranch beef. Mike flew as though he had never been away from soaring. So little lift in the afternoon but he managed to remain aloft 42 minutes working a weak area of lift to the northwest near the power lines. For the longest time he managed to remain at 2220 msl not gaining or losing a foot. I don't recall lift ever getting above maybe 50 fpm. So his coordination and smooth flying gave us that much time in the weak area. For those of you who don't know Mike from before, get to know him. He's a fascinating guy and one of the nicest guys I've met in years. As Alex pointed out above, he has been and will always be a rare asset to our club. Welcome back, Mike.

Carl Engel was out and flew with Harold in Big Bird. Carl hadn't flown for over a month but that didn't show as he did well especially on tow behind the Pawnee. He'll continue working his way towards his Private License doing home study for the written test and getting better each time at flight precision.

Pancho Herrera came out and flew in the 1-26. He is working on flying the Libelle soon. 

Next time we have the towplane from Santa Ynez, when scheduling, we need to remember to start operations early  by scheduling  earlier, as the tow plane needs to leave Avenal about 3:30 p.m.  in order to get back to Santa Ynez with an adequate margin before dusk. Today I think we were still in a summer mode,  and have not adapted yet to the recent time change. Some people were scheduling at 2:00pm and we still had some who had not flown by 3:15 p.m.   They  almost did not get to fly at all before the tow plane needed to leave.

Saturday, October 26, 2013 Auto Tow Day

WEATHER
Visibility: Excellent
Wind: Light out of the North.
Altitudes: 700 ft. AGL
Time Aloft: 5 to 7 minutes off Auto Tow.
Max Lift: Some zero sink
Temperature: Low 80s max.
Comment: Tow plane down. Auto Tow Day declared.
Tow pilot: Jeff Richardson volunteered his Powerful 4WD Suburban for Auto Towing, and did much of the driving as well.

With the tow plane out of action for Saturday, October 26, and the annual club meeting/dinner on tap for the evening, a group of us got together and decided to put on an auto tow day. Jeff Richardson volunteered to loan us the use of his powerful 4WD Chevy Suburban, which turned out to be more than adequate for the job. In fact, some of the highest launches we've had over the years in the 2-33 were achieved thanks  to the power and acceleration Jeff's vehicle provided.  Arriving early around 9:00 a.m., we had a ground school attended by myself, Jeff Richardson and Andy Reistetter and John Harbick. We then deployed the rope, walked it and installed the hinged tow vehicle release and line on Jeff's truck. We spent the rest of the day until dusk doing auto tows. Arriving a little later were Steve Kline, Jan Zanutto, Harold Gallagher, Dan Gudgel, Jim Rickey, Bart Klusek,  and Martin Cansky. At Bart's urging, we also decided to get out the GAPA for some auto towing.  Everyone got some auto towing experience. Bart, who trained in Ireland on winch launching in the earlier stages of his soaring, has already been signed off for ground launch for some time. Bart  flew the GAPA several times. He caught a thermal on one flight,  and had zero sink for a while. Dan Gudgel flew with me in the 2-33 Big Bird,  and then flew the GAPA on at least 2 or 3 auto tow flights that I saw.  Flying in the 2-33 with me were Jeff Richardson, Peter Sahlberg, Jan Zanutto, Andy Reisteter, John Harbick, Martin Cansky, Jim Rickey, Steve Kline, and Harold Gallagher. Most people got 2 auto tows and some got 3. Somehow,  Jim Rickey got only one flight  due to an unfortunate oversight during the mix up as we traded off driving, tow car spotter, wing runner and tail holder-downer duties.  We  used radios for communication, with an orange signal bat for an emergency stop launch signal should radios fail. We are going to look to change to a pure flag based system next time, as radios can be subject to interference, tuning the wrong frequency and some other issues.  Jan took some video of the day's action,  which you can see at these links:

Following the Auto Towing, everyone adjourned to the clubhouse for our annual meeting, dinner and awards presentation. I neglected to record all the awards,  but hope to edit this page and include them soon. Or else another blog page may be created just for the awards.

Saturday, November 2, 2013 Auto Tow Day

WEATHER
Visibility: Not bad, a bit hazy
Wind: SSE at about 10 kts
Altitudes: 1000ft. AGL off auto tow launch
Time Aloft: 15 min.
Max Lift: 2kt.
Temperature: about 80 deg.
Comment:
Tow pilot: Auto tow day, tow plane grounded


We  had another nice day of auto towing at Avenal in the pleasant Fall weather today. A number of people showed up at 9:00 a.m. for ground school, headed by Dan Gudgel. Thanks Dan! It was a very informative and interactive ground school. A quiz prepared by Dan reinforced the learning process, and led to further questions and vigorous but respectful discussion. We all agreed on some further modifications to our launch procedures. We will have the hand held radios available if possible,  but we also agreed on a set of signals involving wing leveling, combined with flag signaling,  so as to not be dependent on the radios.   Radios can have various problems,  such as wrong frequencies tuned accidentally, getting "stepped on" by others using the frequency etc. We then spent the rest of the late morning and most of the afternoon flying from auto tow.  Unfortunately, Dan had to attend a wedding and was not able to fly today.  Jeff Richardson again loaned his powerful 4WD Chevy Suburban,  which really has good auto tow performance. We were at times getting 600 ft. AGL in the 2-33 dual, which is the highest I've ever gotten in the 2-33 on ground launch at Avenal Airport so far. We had some wind, about 10 kts.,  from the SSE,  and operated off runway 13 this time. Morgan Hall arrived in the Cessna 150 on his long X-country that is required for his power license. He attended the ground school,  but had to leave just as we started flying in order  to complete the flight to Watsonville and back to San Luis Obispo on schedule.  Martin Caskey was out with his friend Dennis from Paso Robles and was working on the tow plane. They  attended the ground school but spend the rest of the day working on our tow plane.  Other attendees who flew during the day were John Harbick, Andy Reistetter, Larry Johnson, and Jan Zanutto along with Jeff Richardson,  who did much of the tow vehicle driving. Most people experienced both normal tows and premature releases,  simulating rope breaks at various stages of the launch.   After last week's heavy dirt intrusion into the cab of the Jeff's Suburban and the messy clean up, he rigged up a cool grommet through the rear window/door for the release line and a fancy tape job on the rear window. He also pressurized the interior by keeping the windows closed as much as possible,  and running the air conditioner. He reported much less dust intrusion this time. Hopefully the clean up will be easier this time. Everyone got 2 to 3 flights, except Larry, who had to leave early,  but  got one flight in. Jan Zanutto was signed off with an endorsement for ground launch proficiency. He then got out the DG 100 and proceeded to do 5 tows with it. On one tow, which was the best flight of the day, he got a thermal and climbed to 1000ft. AGL after releasing at 700ft. AGL. We caught much of that flight on these two videos:





http://www.youtube.com/watch?v=SnF9nQtTlUI&feature=youtu.be

Jan also had a tail mounted camera on this flight and recorded the whole flight here:

DG 100 ground launch to 1K

On Jan's last flight, he had a real bone-fide rope break as he pulled into the "full climb". He handled the situation perfectly,  and was high enough to make a 180 deg. pattern and land normally on runway 31, rolling out and stopping right at his T-hangar. After Jan's rope break today, which appeared to be just related to the rope finally having enough wear to be significant  after about 150 launches, I plan on replacing the 1/4 in line with new rope next week.

Jeff volunteered to do one more ground launch operation next week with the Suburban, and should get signed off for the ground launch endorsement next time.  He also plans on flying the 1-26 next week on ground launch.

Saturday, October 13, 2013 Beautiful Fall Weather at Avenal

WEATHER
Visibility:Excellent
Wind: Light SSE early morning, SSE at  10-12kts. max. in afternoon.
Altitudes: Approx. 7000ft range west of Black Mtn. in convergence.
Time Aloft: ???
Max Lift: ???
Temperature: Low to mid 80s. maximum
Comment:
Tow pilot: Steve Schery most of the day. Alex Caldwell did last 3 tows.


Another nice Fall day was had at Avenal today. The weather was very pleasant,  just barely hitting the low to mid 80s,  according to my Mother Nature provided on-board temperature sensors.  The winds were light all day,  mostly out of the SSE. Operations were on runway 31 early on, later switching to runway 13 when the wind came up to about 12 kts.  for a while.

There was lift over the valley, properly known as the Kettleman Plain,  with Andy Reisteter in the Russia, Joe Anastasio in the PW-5,  and Jan Zanutto in the DG 100 staying up most of the afternoon and reporting they thought there was a convergence over the valley.  There were a number of good looking dust devils during the afternoon just along the edge of the Kreyenhagen hills to the West of the field, and a few more right near the field just to the NorthWest. The RASP soaring forecast  was saying thermals might top out about 3500ft MSL at 3:00pm at the Avenal Airport.  I'm not sure what altitudes were actually achieved by the group above.

ER was calling near Avenal on the radio, I believe he had taken off at Hollister and was somewhere to the west of Black Mountain.

Early in the day,  Dan Gudgel was flying with his students Tom Nichols and Dan Clark. Tom left about noon, but Dan Clark and Dan Gudgel flew two more flights late in the afternoon.

Keith Curry, Mike Paoli and Vance Ray were out and all made solo flights in the club 2-33s, in addition to running wings, hooking up towlines and fueling the tow plane.  

Al Leffler flew over from his ranch at Poso in his beautiful Sport Cub. He stayed for quite a while,  and imparted some of his vast experience in contest soaring and cross country soaring to some of the newbies on the front porch. We were treated to a very short take-off when he left to fly home. For those who don't know, Al is a two time U.S. Open Class national soaring champion. He has flown in and won many other soaring contests over the years in both the Open Class and the 15 meter class. He has been a regular contestant and winner  at the Central California Soaring Club Spring Contest over the years.   He may be best known, however as the coiner of the term "Kiddie Gliders" when referring to 15 meter gliders with their limited wing spans compared to Open Class ships.

 Yutaka Buto came out and helped out but did not fly.

 Pancho Herrera arrived late and was working on 4M the Standard Libelle. He is staying over night at the clubhouse tonight.

Darin Council came out and is working on getting checked out in the 1-26. He flew with me and made two accuracy landings. He also has now earned his A, B and C badges, which will be reported to the SSA, and should appear in Soaring Magazine. 

Jim Rickey arrived from Hanford in his beautiful Cessna 210.  After performing duties as chef for our hamburger lunch, he  flew a 1 hour solo flight in Big Bird. This was only his third solo in a glider.  With this flight, he  earned a B soaring badge, which was presented on the clubhouse porch by SSA instructor Alex Caldwell.   Earlier in the same day, Jim had been flying Young Eagles rides in the Cessna 210 with the EAA group.

Matt Potter,  who is a very experienced hang glider pilot, was out again,  and is checking out the club.  He is thinking of converting to sailplanes.   Matt has already passed the private pilot glider written exam, which is a hurdle for some the rest  of us.

Steve Schery performed towing duties most the day.  We were very grateful to him for giving up his own soaring day to tow for us.  Alex Caldwell picked up the towing for the last few tows of the day.

Hope I didn't forget anybody. Please send any pictures,  as I was too busy to think of taking any today.

Saturday, Oct. 5, 2013 - Jim Rickey Solos

WEATHER
Visibility: Excellent
Wind: SSE 10-12 kts. early, light and variable later.
Altitudes: 7,000 MSL over the mountains
Time Aloft: ???
Max Lift: ???
Temperature: low to mid 80s
Comment:
Tow pilot: Peter Mersino

On Sunday Oct 5, Jim Rickey soloed in the 2-33 "Big Bird", with Peter Mersino doing the towing, and Yutaka Butto running his wing.  Congratulations to Jim! I got it on video from the above link for your perusal and critique.  It was a really nice day out there at Avenal. Maximum temps I think were in the very comfortable mid 80s,  but there was lift over the valley most of the afternoon. Just enough to stay up, but not much turbulence on tow. The wind was out of the SSE most of the afternoon. Not really very windy, maybe 10 -12  kts.,  but just enough to cause us to operate off runway 13 most of the afternoon.  It became light and variable late in the day,  and we switched back to 31. Andy was up most of the afternoon in his Russia. Karl Kunz decided to not put together the AS-W 20,  but couldn't resist flying, so he went up in the 1-26.  Dan Gudgel stayed out there all day with his student  Dan Clark.  George Garcia from Las Vegas was driving along highway 33 on the way to a Chargers/Raiders football game in the Bay Area. Don't ask me how he got lost and ended up on Highway 33. Anyway, he happened to see the gliders, so he stopped in and got an introductory lesson.   Jack Knudsen was out with his Dad,  and flew Big Bird, staying up very well in the weak conditions. Mike Paoli and Vance Ray were out and made solo flights and we all hung around the patio eating the lemon cookies left there by Peter. There was quite a bit of dirt that had blown onto the patio from the wind event we had on last Thurs./Friday,  and we all took turns sweeping it off the patio.  A side benefit of the big wind was that all the tumbleweeds we cut last week have disappeared. They are probably in Kern County somewhere.     Morgan's friend from hang gliding,  Matt Potter,  from Los Osos,  came out.  Matt is a hang glider pilot and has quite a bit of student power time over the years.  He says he is going to join the club, get his gilder add-on rating,  and wants to get his own glider eventually. He had one lesson with Harold last year, along with a X-country  flight with Morgan in the DuoDiscus.
