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

The Lake Elsinore Soaring Club is looking for qualified CFIGs to become part of our instruction staff. The club is located at Skylark Airport in the city of Lake Elsinore, California. We have year round soaring and operate from 10:00am to 4:30pm on Saturday, Sunday and Wednesday. The club has 2...

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....

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...

An even better question would be where on the hero list do they go when they don't get away with it and have no back up plan in place? I know where some have gone and I don't want to go there just yet! At 20:12 25 September 2003, Tom Serkowski wrote: So where on your 'hero list' would you put...

I have listed a Scott oxygen mask (with built in microphone) and a diluter demand regulator, with blinker and gauge at ebay.co.uk. If you are in the UK and are interested, please use the tinyurl links below to find out more. If you have any questions please send them to me via the link at...

My PW5 came with a very nice Cobra trailer that originally was for a Discus. It's all metal (no Fiberglas). Needless to say it's way to big for the PW5-5 although it has been converted very nicely. I'm sure it would be very easy to convert it back for a 15 meter ship. If anyone would like to...

This year's Gauteng regionals has closed out after 4 days. It appears that high winds on the last two days precluded further competition. For a full list of Trophy awards and final results see: http://www.sssa.org.za I see the SSSA webmaster came in at 10th in his class - at least he's out there...

Asked a question I could not answer yesterday..... Why does the towplane indicated airspeed always indicate so much higher than the glider behind? As much as 10 knots. Consistent with the Pipers, Cessnas and Grummans. And yes, compensated for kts. vs. mph. Thanks, Michael

gelcoat ailess deux ans "ailess" did not translate with babelfish I presume the phrase means "gelcoat 2 years old" gary

Looking for a Ventus C with B fuselage, with S/N 327 or higher. Must have trailer. Cheers Mark

After hours of agony with the factory supplied cushions, we are having custom cushions made for our Duo Discus. Anyone interested can contact us. These will incorporate impact absorbing memory foam. We made similar cushions for our towplanes and they are fantastic. We would need a pattern for other...

It seems to me that the ASA is just a private little racing club for those with expensive sailplanes.In my opinion the reason many people drop out of soaring after getting a license, is that there is no place to fly other then commercial operations which are more expensive and are focused on other...

Dave, I've been pleased with the newest upgrade in the software... I like the screen options very much. On a related note, will ILEC include an integrated GPS engine anytime soon? This seems like it would be a realatively straight forward upgrade of the system and would allow me to unclutter my...
