Intermittent Uncommanded Roll Input

[Flash_111]

Past few weeks I have experienced intermittent uncommanded roll input in the F-14A during MP flight. It has occurred with both AP on and off. Malfunction occurred 3 times in about an hour. All were rolls to the right. First (ATT HOLD ON) was a minor disruption (~10 degrees of roll, <5 degrees pitch), second (ATT HOLD ON) was a little more severe, and third (AP OFF) we were rolled through 90 degrees. Last week I had another event so severe and abrupt that I blacked out for a few seconds and then when I came to, the oxygen system had stopped working. Rapid descent to 10 thousand kept me from blacking out. I had reports of similar events from guys in my group over the past week or two. I checked all my bindings for double bound axes and there are none. It may also be a form of desync since this is all multiplayer. Examination of DCS.log was inconclusive. If it happens again with a RIO on board I will make sure to get his DCS.log to look at also. I realize this is going to be a hard one to diagnose but I will keep working on it to see if I can isolate the bug or narrow it down to a specific system. I will update the thread with my findings.

I've had this with AP on at high altitude and above a certain speed, though not a complete roll. The plane would roll left, then counter back level, and repeat this oscillation until I either lowered speed or altitude.

Above the certain speed at which the AP no longer functions?

What speed is that? The HB manual and Chuck's Guide say nothing about a speed limitation on the autopilot.

@near_blind Seems vital information to add to the manual in the Docs folder.

You mean the one that is never updated?

It was happening at subsonic speeds below 0.9imn, and altitude was somewhere in the 20s if I recall. It also happened with the AP off.

Apparently. Chuck is good about updating his guides, but the limitation isn't mentioned there either. Apparently the only source is NATOPS, which according to another user, is "Distribution C" meaning we aren't supposed to have it. Ergo, we're often told to "RTFM" on manuals that are incomplete, not updated, or we aren't legally even supposed to have.

The D is distribution C. Although even that….mmmm I certainly believe the -1A is….even declassified you still can’t get one with a FOIA request.
