Question Troubleshooting Auto-Pilot Issues

[lrobichaux]

I’m in the process of troubleshooting autopilot drift, jerkiness and overall unsatisfactory performance smoothly holding course, altitude and glide path. This morning I noticed that the G3X shows that there is no software installed on the pitch and roll controls. Have no clue if this is normal, or if it’s an oversight at CubCrafters. Any thoughts or suggestions would be appreciated.

The blank entries for roll and pitch usually mean the servo switch was off. Servos must be powered for their status to be read.

With avionics bus on, then servos on, the PFD mode annunciator should show briefly PFT (pre-fight) which is the servo test before AP engagement is allowed.

It would not be possible to have AP engagement if no software was loaded in the servos. Servo software is updated with each G3X software update as long as the servos are powered.

That’s the answer. Appreciate it.
