    Hello,

    After the upgrade to v0.8.0 I am having issues with the altitude hold mode in my beloved Arrow III.

    When I switch on the altitude hold mode the plane goes into a very steep climb... until stall. It is as if it remembers an altitude setting from earlier and is trying to climb back very aggressively.

    I have tried landing during flights and then switching on/off the AP and altitude hold mode to see if I can sort of 'reset' it. No luck.

    Anyone else having seen this?

    I had the exact same issue today, think I gave the ATC controller a panic!

    @SuperKaro2014 exactly the same issue I have been experiencing after the upgrade. It seems it keeps a memory of the last VS setup (although there's no such VS option available, right)

    The AP roll issue is also ineffective, I have tried it once and the AP got crazy afterwards forcing a steep curve to the right making it impossible to use after all.

    I find that it seems to behave much better when the autopilot is engaged. Altitude hold becomes disengaged when the autopilot is turned off. When it is subsequently re-engaged with the autopilot off it can react strangely. However this behavior does not appear to be consistent.

    Thanks for the feedback, I'll submit a ticket with support and reference this thread.

    @SuperKaro2014 I've had a similar experience as well, I usually set the AP so it will follow my flight plans and allow the plane to climb to my desired altitude. It does go to about full climb, then slowly back down and then go back up until I click on the invisible location to have it hold.

    @davidcrum I find Altitude Hold to work very well for me if engaged after first turning on the Autopilot. It appears to hold the altitude indicated when engaged even in a steep climb or descent as long as the autopilot is doing its thing. Altitude Hold becomes disengaged automatically when the Autopilot is turned off. I noticed that with the Warrior II Altitude Hold will not engage unless the Autopilot is functioning. Of course this is how it works when the Autopilot actually has an Altitude Hold function, and I am thinking that this may be the way JF has made an effort to improve its behavior. Be that as it may I also have experienced wild behavior when attempting to engage Altitude Hold when the Autopilot was turned off and at least for now I will simply avoid doing that.

    Similar for me as well but only after the SU5 and hotfix update...

    Do you have State Saving enabled? If so, try disabling it and restart the sim.
    I've read multiple times that people had issues with the AP that got resolved by simply disabling the state saving. My guess is that exiting the aircraft at a certain state results in some state being saved that is restored in a way that the AP then doesn't work properly.
