Google, Dynon and probably others are offering low-cost instruments such as this one for the Experimental market:

Since the G5 includes attitude information it would be illegal under current rules to take it to a glider contest, but... What we have here in a very compact 3 1/8" space is all the flight data you need including airspeed, altitude, heading information, vertical speed and slip/skid. The built-in GPS will indicate ground speed and of course you have attitude info. I wonder if this would satisfy regulations as a stand-alone basic instrument. You would only have to add a vario, flight computer, radio and transponder (PFlarm integrated in moving map) for a very compact panel. Redundant altitude info would come from the vario/gsp which also today often displays airspeed if so desired.
With back-up batteries, what could go wrong?

Interesting instrument. Now, does anyone know if this device would be legal for use in the USA for an experimental glider and could this device be used as a replacement for an ASI and and altimeter?
