I recently installed a G5 in my aging panel to replace a failing vacuum AI. The G5 was an easy choice as a G3X upgrade is in the future.
Installation was straight forward and easy as was the calibration. A test flight has me scratching my head.
On normal takeoff, straight out with gentle climb the G5 "aligned" itself many times. Granted the air was not smooth but I did not expect the constant "alignment". After about 5 minutes it seemed to have settled down and would show level flight.
Turns about a point, climbs, descents and S-turns all caused the unit to display a descending left turn with the occasional climbing turn after returning to level flight.
The slip/skid ball is not very sensitive. A full skid moves the ball very little while the analog slip/skid in the Trio is all the way to the left.
I turned everything off to see if electrical gremlins were causing the problem. No difference that I could notice.
Needless to say the AI is not to be trusted in this particular instrument. I returned to base, reset to factory defaults and went through the setup and calibration once again. The results were no different. the AI has a mind of its own.
I guess the next step is to upgrade the firmware and try again.
