(per FAA Flight Advisory) You might want to factor this in to your badge or record attempts as the GPS trace may be unusable or have holes in it. This would be especially true at higher elevations like wave flights. The effected area is huge, covering most of Nevada and southern California. For...

Thinking about new trailer and would like to know pros and cons from Avionic owners. Since Avionic is about 40% cheaper than Cobra right now it looks like good deal.... Also if anyone owned Cobra and Avionic and can compare both models. Thank you Pavel

I am wondering how often a truck for towing a glider trailer might be an advantage? I have yet to buy my first glider, but of course and thinking that the next vehicle I purchase should be a good one to tow with (Incidentally, thinking of the GMC/Chevy Canyon/Colorado, with the 2.8L inline 4...

What is the maximum altitude (about) when the mobile phone becomes useless? PeterK

Our club has a K8 with extremely uncomfortable seating arraignments. Basically we are using a combination of foam pieces and misc cushions to try to make the glider usable. After about 2 hours, it is pure torture. The basic glider has a metal seat pan that covers the landing wheel. The seat...

In the latest edition of Soaring magazine there is an article about TLAR. For those not familiar with TLAR, it is a landing approach teaching method that is based on angles as opposed to elevations and distances. Using angles automatically compensates for variations in altitude. On downwind , if...

I am looking to purchase a new (to me) XC ship. Which ones have the largest/roomiest cockpit? Not for a tall person, one with broad shoulders, about 5'9 and 200lbs. Discuss and Thank you in advance!

All, I've place my ASW20b on the market, some of you in the states know it's Id (21) and know it's a fine ship. If interested please see the ad on W&W at: http://www.wingsandwheels.com/wantads3.htm Respectfully, Rick Culbertson Colorado, USA

There is an interesting discussion here at http://www.postfrontal.com/forum/topic.asp?TOPIC_ID=5589&whichpage=6 with a lot of pictures I have taken out of new PNAs with 800-900 nits displays. This PNA has also a spare RS232. I am searching for a Dell Streak to compare, but it is was gone out...

I have just posted up to Al's Gliderforum a german language copy of an overhaul manual for the Solo 2350 2-stroke engine as used in all of Schempp-Hirth's sustainer models, as well as the Ventus CM and the new LS-8t sustainer model. This document is quite complete with a good number of color photos...

In addition to max gross weight, some glider manuals specify a max weight for non lift producing components. But I haven't found much discussion of the significance of exceeding the max or information that would allow one to calculate the weight of non-lifting components (like a breakout showing...

"cdubya" wrote in message ... Very little on the web about the Bowlus BA-100. VSA has plans for $250. I just need to get details on Cockpit Pod. Anyone have plans or have access to one that I could visit and take some...

The proposed rule changes for 2008 US competition soaring are posted at SSA.org/sailplane racing/rules & process. Input is welcome. Final rules proposals go to the SSA for publication in the board "Blue Book" in mid January. Seasons Greetings to all from the SSA Competition Rules Subcommittee UH H...

Hello, Can anybody give me some polar curve data of the Discus at very high speeds? (i.e. at Vne and/or beyond). Many thanks in advance! Karl

I'm not alarmist to say that the FAA is going to ground 80% of the senescent USA glider training fleet sometime soon. The only question is when. The L-13s are being recycled. The few people who know how to properly inspect and keep the 27 wooden Schleichers KA-* gliders flying safely are...

The Sparrowhawk is the worlds most fun to fly sailplane available hands down. Jim Payne just set 8 new USA National records in a Sparrowhawk in 2009. WOW!!! No other standard sailplane comes close to it's maneuverability and agility due to it's low weight and low moment of inertia due to the...

Comment period ends 5 April. It would require an inspection within 60 days to ensure the elevator control attachment slot on the vertical stab be measured. One which caused a fatal crash in UK last year was found to have been enlarged. If the cut-out has been enlarged, the factory must be informed...

I have a 2009 Cobra trailer designed for a two seat glider. The tires need replacement. The original tires are of size 195/70R14. I cannot find the direct replacement trailer tires in the United States. I can find passenger tires of the same size, but not trailer tires. There are a couple of...

I am a big believer in having some form of survival kit in my glider. Even in the "wilds" of the midwest I can get stuck outside for a while before being "rescued". I am always on the lookout for items to add to my kit which I have built up over time. Whistles, fire starters, signal mirrors,...
