Caution warnings

[bryan]

Hello
We have a skyview fitted to our E33 Bonanza, coupled to Garmin 430. At any stage of flight, and at intermittent intervals and with no noticeable reasons the young lady in the Skyview chooses to issue a caution warning. There are no messages posted when this happens, nor any indications as to what may be causing this. This may happen 5 + times on one flight, once on another and sometimes not at all. The other day it was about 10 times.
Has any one any ideas.
Cheers :-?

Check out the Audio Alert Details starting on page 10-5 of the Pilot User Guide to try and narrow it down.

Thanks, Mmarien, but there are no messages shown in the message window when this occurs. Occasionally the message icon in bottom row will flash, but nothing is displayed. Makes it hard to work out the reason for it.
Cheers

If you have self clearing alerts, one or more of them might be activating then clearing very quickly. When this happens the audio will alert but the visual clears before you react. Check which alerts you have as self clearing and set these to latching. This way the problem alert will stay on the display long enough for you to figure which one it is. It will be a pain in the rear for a while but you will eventually find the culprit alarm.

Good luck.

The EMS warnings tend to be specific rather than caution so they can be eliminated. I would eliminate all the caution warnings that pertain to the equipment that I don't have and specifically look for and try maneuvers that create the warning. When they happen check the PFD rather than the warnings button area. GPS ASSIST caution warning appears on the PFD for sure.

You may also may want to check the user logs or black box data. You might identify it with SavvyAnalysis. A POSITION SOURCE caution would produce fluctuations in the path or elevation. Or just use Excel. Grab a column and plot a line graph to check for anomalies. This was just a half second of pressure altitude failure.

Each engine item under SENSOR SETUP has an ALARM option selection at the top.
