The Air Force Test Pilot School has a Blanik L23 with a Gateway
tablet PC in the front seat. It had better resolution and screen
visibility in the sun than my own Gateway M1200 or IPAQ 3950.
No, I haven't installed the M1200 in a glider, but use it outdoors
quite a bit. Would consider the screen as useless as the IPAQs in full
sun. This is pretty normal with touch screens.
TPS is experimenting with dynamic soaring, and able to view pretty
accurate wind shear information on the tablet PC screen, along with an
attitude indicator and satellite imagery. These tests supposedly
include dynamic soaring the Blanik down to 100' AGL, which could be....
Well, interesting.
The best GPS display to rely on in the cockpit would be the "Black
and White" one in the panel. Call it an SN-10, 303, Garmin, LX7000,
GPS-NAV display, or whatever you like. The moving map is nice, but
about as necessary as parachutes at 100 feet.
