So when the Garmin system went down, other than HF Communications
provided by a portable transceiver, and the flight controls, the only
other functional instruments and operable systems you had were the OAT
thermometer, EGT, magnetic compass, attitude indicator, altimeter,
intermittent tachometer and airspeed indicator? No navigation
equipment, auto pilot, VHF communications, fuel gages, engine oil
pressure nor temperature gages? Have I finally got it right?
When the system went down the only things I had was My Portable GPS, HF Com,
Portable VHF Com, Steam Attitude Indicator, Steam Airspeed Indicator, Steam
Altimeter, Whiskey Compass! Every thing else was tied to the G1000 and was
useless or not to be trusted as accurate in that situation. They don't even
have a slip/skid ball in the thing when the G1000 goes blink that's
intergraded also!
Thanks for the information.
Can you tell me more about the overpressure in the wing tank(s), and
the fuel entering the pitot-static system causing the loss of the
airspeed indicator? Here's all I have:
Apparently the added pressure in the fuel
tanks pushed the floats in the fuel tank up, which got the Garmin
confused, causing an error that made it reboot. The loss of the
airspeed indicator was caused by fuel vapors entering the pitot
tube -- which also caused the CO2 detector failure!
Has anyone figured out what happened to cause fuel to enter the
pitot-static system? Have you any idea of the magnitude of the added
pressure you mentioned? Where there rubber bladders in the wing
tanks?
