> Every Air Force aircraft that I've flown had a "peanut" gauge - a backup attitude indicator to confirm what position you were in. I would think that her aircraft had a backup....hopefully. Not a time to be the weather! She did well.
In the case of a light plane like the Commanche, the attitude indicator (aka vertical gyro) IS a peanut gauge. There's no backup attitude indicator. Instead, if the attitude indicator fails, instrument rated pilots are trained to use the remaining instruments: airspeed indicator, altimeter and turn coordinator. The turn coordinator is a rate gyro that doesn't tell attitude but does indicate if the aircraft is turning. The attitude indicator and turn coordinator always use independent power sources; typically the attitude indicator is powered by a vacuum pump while the turn coordinator runs off the electrical bus.
