Required if you will use your transponder. 2) Pitot/static/altimeter (only required for IFR - and the pitot system cannot fail). For this test you will probably want to be present if you have an experimental altimeter (like the GRT, Dynon, etc...) that needs to be calibrated. Even if you do not plan to fly IFR, you should either do this or do something like what Al describes to give you a general idea that everything is working and accurate (must be done by the shop to be legal for IFR). -- David Leonard Turbo Rotary RV-6 N4VY http://N4VY.RotaryRoster.net http://RotaryRoster.net On Sun, Jan 17, 2010 at 8:59 AM, Steve Thomas wrote: > Al, > > Yes, please, send the graph of in. of water vs. airspeed.
