missing info Is the Autopilot (still) not working all the time?

[karpiyon]

I find that when I engage the autopilot, e.g. attitude hold and steering select, it will not keep to the current SP and will start loosing altitude.

I verified all autopilot switches are set properly adn no warnings. Speed was ~360knots.

It does not happen all the time but lately most of the time it simply won't work for me.

 

Any limitations to the autopilot?

Do you have the air refueling door open? That would cause the autopilot not to engage.

Autopilot works great on my end. Refuel door open, or  gear still down? Not a real issue in the F16 currently, but make sure your stick gives no input. Maybe a little deadzone is needed. When it disengages, is the AP switch  still engaged? Or did the spring loaded switch jump back in the off position? A track file would be helpful in that case when it happens.

There are no issues with the F-16 AP on my side

Yes the AP switch is still engaged adn I do not touch the stick - no input from it

Hard to tell without track file. When the AP switch is either in alt hold or attitude hold, where do you set the steering switch left to it? heading select or steerpoint select? Can you try that with a mission you start in the air, so you dont miss any steps on the ground that prevents the AP to work.

I'll try to log the output from the stick again.

I'm sure I operate the knobs correctly - been doing this for years now.

Thanks

Okay, then the only thing I can imagine is something on your hotas is bound to interfere with it. Double bound AP switch dont know.

Maybe, last idea: Disconnect all input devices from your PC. Use the keyboard shortcuts to test the AP. If it works without the HOTAS you have at least an idea what causes it.

 

EDIT: Seems like there is no keyboard shortcuts for the AP. For this test you'd have to set them first of course.

i'll try...

[karpiyon]

it's the stick...

When i disconnect it it is working fine.

It's a Logitech X-56 and  it takes it a long time to stop responding - i'll try to play with the dead zone

Glad I could help Also check if joystick button binds interfere.
