can not reproduce A/P BALT not working frequently

[jed40]

Hi Guys,

It seems there is an issue with A/P on F/A-18 with BALT mode. Frequently the BALT mode is impossible to engage. When it's the case, we can see on Left MFD "A/P" is appearing, but the plane does not keep altitude. If I cancel A/P with joystick button, A/P disappear from Left MFD. Sometimes, after few attempts, it works, but I noticed that if disengage itself without any axis entry, and the altitude changed slowly...

I made a quick flight with the Marianna Island Instant action "Free Flight". The track of this flight is attached.

Have you already see that problem ?

I didn't see any report concerning this issue.

Thank you for your support.

Hi @BIGNEWY

Thank you for your quick feedback. I tried again, and I got different result depending on the Map.

On Nevada and Mariana Islands, to activate BALT mode, the plane MUST BE perfectly HORIZONTAL in both axis. If not it cannot activate. And I noticed that it's very sensible at at the rolling tendency. If it's not perfectly horizontally trimmed, the plan start rolling left or right even with A/P on BALT mode. I must engage ATTH mode to keep horizontal attitude. On all the other map A/P is less sensible at the attitude of plane during activation, and it can keep a certain stability even with a rough trim setting...

So please if you can test on those map (Mariana and Nevada) thanks again.

Have you tried adding a small deadzone to your stick? The Hornet is unreasonably sensitive to an uncentered stick when compared to other modules. If your stick is even half a millimeter uncentered, the AP won't engage properly. I solved this issue by adding a deadzone of 2 to my stick.

@Nealius I just tried your recommendation, and it seems to solve my problem. I put +3 deadzone for X and Y and also put +5 for rudder in case... and everything works like a charm !!! Many thank for your help;

Have good flight
