This came up in another thread…hoping G3Xpert can chime in.
In my G3X setup, as well as the Dynon Skyview that was in my previous airplane, it seems airspeed is required for the system to display an attitude solution. Recently I had a pitot line break, so I had zero airspeed in flight. To my surprise the artificial horizon drifted to the point of being unusable for instrument flight (I was VFR at the time).
The concern here is obviously that an airspeed failure could lead to loss of control if in actual IMC. Is this a known failure mode? I would assume there should be some cross check that would provide the ‘red x’ over the airspeed indicator and tell the G3X to disregard the airspeed input (and perhaps use GPS ground speed as a backup?).
The G5 was of no use, as it was affected by the common pitot line failure.
As is, this gives me serious reservations about using this instrument suite for actual IMC operations…
Thoughts?
