Auto Pilot failure

[eddies]

Hi Guys,

I was recently did a 3700nm trip and about half way through this trip, the roll servo came up with a roll servo failure message in the title bar of the Skyview screen.

This occurred during engine start-up.

While letting the engine warm up I tried to do a network discovery, but to no avail, I then tried a forced discovery which also did not work.

We continued the trip without the roll servo for the rest of the day.

The next morning the roll servo failure message was gone, but we had a pitch servo failure message, I went through the same steps and again could not get the servo to come online.

The next morning the auto-pilot was no longer available.

I tried for the next two days to re-discover the servos and nothing seemed to work.

On  the third day when I did the discovery again, the servos magically appeared and the auto pilot started functioning again, I had no further issues for the rest of the trip.

Does anyone have any ideas?

Cheers
Eddie

I've seen something similar a couple of times since upgrading to SV 6.2. On power up, I'll get a servo failure message on one or both servos. Cycling the circuit breaker that the servos are connected to always fixes it. I assumed it was a power up glitch -- hasn't happened in the middle of a flight though.

Eddie - next time you see that, can you see whether cycling the power to the servos changes anything? Also, do you turn on your servos with the same switch that powers up your SkyView display? Or, is there a separate switch which provides power to the autopilot servos and other things?

OK will try cycling the power to the servos next time.

At present the servos power up when the Master switch is turned on, which also powers up the Skyview.
