Lapse Rate Question by Waduino
Have you tried a Google search? It turns up quite a bit of info. In case it helps: The dry adiabat is the rate at which unsaturated air cools when lifted. (Ballpark 3 deg C / 1000'). The moist or saturated adiabat is the rate at which air cools when lifted, once saturated. (Ballpark 1/2 of the dry...

Plasma Ropes ----- Help by Dave Martin
To any club using plasma ropes in place of steel. Having read the benefits of this type of rope, several UK clubs are interested in its use. One major obstacle to this, is cutting it during a launch, in the event of an emergency So far the best methods appear to be an axe an anvil type cutter.

Altitude gain: qualitative analysis by Chris OCallaghan
Flew on Sunday in non-stable conditions. David Pixton flew his Ventus 2b at approx. 800 lbs, and I flew my Ventus 2bx at 1150 lbs. Because conditions were turbulent, we were unable to do any smooth air testing, but during the course of 10 pull ups (entry 100 knots, exit 60 knots) we observed the...

Turning radii and spanwise airspeed distribution by JJ Sinclair
Good observation, Bill. Most long wingers have found it best to keep the nose pointed towards the outside of the turn. It helps the climb. Your yaw string should be telling you to, "Put your foot in the inside hole". Just don't do it. Does that make sense? JJ Sinclair

Sport Pilot (was SoCal CFIGs needed. by M B
An unpowered light-sport aircraft (e.g. glider) would have a maximum never-exceed speed (VNE) of 115 knots, as VH is not applicable. This speed limitation also limits the commanded kinetic energy of an aircraft flown by a pilot holding a sport pilot certificate. For a VNE equal to 80% of the...

Need G-103 Acro Master Cylinder by Ray Lovinggood
Our club's G-103 Acro needs a new brake master cylinder. We can probably get one from Grob in Ohio within several weeks, but we would like to get one sooner. Does anyone, anywhere, have a master cylinder they would sell us? Then, we would pay overnight freight to our club's location in North...

Solo in a 2-32 by M B
Hollister Gliding Club in northern california solos students and uses the 2-32 as a primary trainer. I think their reasoning is that it is useful for sightseeing and for training, and for those who are 'big boned.' If I owned a glider operation I'd personally have students solo an $8000 2-33...

For Lennie - soaring on Mars by Mike Borgelt
The pressure difference across a thin vertical slice in a fluid is dP = rho x g x dh where rho is density, g = acceleration due to gravity, dh is the vertical thickness of the slice. So by rearrangement we get dP/dh = rho x g dP/dh is the vertical pressure gradient(rate of change of pressure

SSA Soaring Magazine by Mel Eastburn
I am attempting to dispose of a very large collection of gliding books and mags acquired over many years by a friend who died very suddenly recently. Any proceeds will go to charity. Amongst this is a complete (I believe) set of the US SSA Magazine 'Soaring' from mid 1966 with some earlier issues....

Pullups, I stand corrected! by Derrick Steed
Lars, I think you may be forgetting something else. For the same speed of travel, the light glider is using energy faster than the heavy glider. It seems paradoxical, but it is true - look at the loaded and unloaded polars to see that the heavy glider is either: a) travelling faster for the same...
