I have a couple of issues with my new (to me) Ovation that maybe someone here have experienced and could provide guidance.
1) My skywatch system, interfaced into my 530, seems to think that my own aircraft is traffic to be alerted. I get the TRAFFIC TRAFFIC alert, only to realize the traffic is me, in my location and altitude. I just discovered the test mode - does this cause the device to detect my own transponder and suppress this alert - was going to add this to my checklist and see if it helped? Or is this a fault in the equipment?
2) My 530 com gets lots of ignition noise, to the point of rendering some atc transmissions unreadable, and is just generally annoying. The old com under it has much less noise. What can be done to help the 530?
3) The really big issue. Yesterday afternoon on a long flight, VFR above a cloud deck I noticed that the King 150 autopilot wasn't tracking very well and had me right of course. Then I noticed that the AI was starting to slouch off to one side. So what was happening in nav mode was that the airplane was following the AI off to one side a bit, but then would decide to bank back the other way to stay on course, and these two would balance out and I'd end up level a bit to the side of course. So, it was obvious what was happening, there was an AI problem. Checked vacuum and pressure was fine. But I turned on the electric standby vacuum pump anyway to see if that helped. This bumped the vacuum pressure a very tiny bit, just enough to make clear the standby was working. But without standby the vacuum pressure was normal. So I figured the problem was with the AI not vacuum. But then surprise surprise, a few mins of both pumps running re-erected the AI. So I'd turn off the standby, and 5 mins later, same problem. And again, vacuum gauge showing no issue. Did this 2-3 times, and the standby helped each time. So I left the standby running for a half hour. Turns out weather at my destination was clear again, so I turned off the standby one last time, and this time the AI was fine. Even stayed level when taxiing back with low-ish pressure from the engine driven pump. What's going on?
What's scary is how difficult this would have been to detect IMC. Thinking about backup AI in the one open spot on my panel, recommendations?
thanks in advance for any thoughts or insights!!!
