Thread: Issue with flying straight (AP, A320)

  1. #1

    Default Issue with flying straight (AP, A320)

    Dear Simmers,

    I've reinstalled the whole game today since this problem makes MF2020 really unplayable for me.
    Flying with Thrustmaster Hotas X, using flightplan, IFS and AP on the A320 always starts to get into a yaw banking to the left or right with the (auto) rudder active to the right or left respectively to counter it. It looks like having side winds of 40knots but to test I set the weather to fine and still the same.

    When departing or taxiing I can control the Thrustmaster's rudder nicely and all looks pretty good calibrated, but during flights the yaw gets heavier and heavier...

    Any clues? I don't have drivers for this joystick installed since I can use M$-Windows joystick calibration tool just fine. I'm wondering this has anything todo with the AP maybe?

    I have what sounds like the same issue. With a simple heading hold AP flight configuration, I can't get the aircraft anywhere near the desired heading, wings are banked left 15-20° (a/c is not turning, though), and, on the external view, you can see the rudder kicked hard left.

    My joystick (a tried and true Sidewinder) doesn't have anything to do with the scenario.

    As of two updates ago I now see this problem regularly on what used to be my go-to "reliable" aircraft (Caravan, Baron, Kingair). The autopilot (awful to begin with) seems to have taken a huge step backwards.

    Winds, aircraft loading and balance are not factors, either.

    Same here. And today I tried without Joystick connected flying by keyboard and still same issue.
    No mods either (completely deleted and new installation)....
    Sigh.

    Do you have another keyboard to try? it might be a keyboard issue?
    BTW, you are not in roll mode are you?? Check the panel.

    That's REALLY weird, but what is the aileron deflection? A left bank usually implies left aileron (or maybe near neutral), and left rudder with it should be turning the aircraft to the left. There would be nothing left to stop the turn.

    In the picture I see no aileron deflection, so that's rather weird. Does it fly normally with the AP disengaged? Might be a program bug?

    fly235 and jfitler - do you have any of the Assistance settings switched on, or AI control from the in-flight drop-down menu?

    Thank you for replying with suggestions. When turning off AP the rudder goes back to normal.
    I'll try tiger's suggestions to switch off Assistance settings .... now I have almost all on "Custom".

    To reply to the previous input...

    -do you have any of the Assistance settings switched on - no, all are off
    -or AI control from the in-flight drop-down menu? - no AI control
    -Does it fly normally with the AP disengaged? - Yes - hand flies just fine with no AP
    -That's REALLY weird, but what is the aileron deflection? - visually there is no aileron or elevator deflection. Aircraft is not turning or climbing but flying in a straight line. In real life this attitude would be difficult to hold without considerable rudder and aileron interaction, which does not appear to be happening.
    -Do you have another keyboard to try? it might be a keyboard issue? - Keyboard functions normally. Again, the problem appears ONLY when the autopilot is activated.
    -BTW, you are not in roll mode are you?? Check the panel. - If you mean, is the aircraft in the process of executing a roll, no. Note the degree of bank in the screenshot. Other than that, the plane is in straight and level flight and, once the autopilot is activated (using only the heading and altitude hold features), then everything goes to hell.
