Issues when taxiing

1st Official Post

    Hey guys, got a problem with taxiing.

    No matter what aircraft I‘m using, when starting to roll, the aircrafts always start to move a bit to one side alone. And no, even if I‘m using the digital yoke pad instead of moving my phone. Is there some how an inbalance of the engines? It is quite annoying. The amount of going off the center line is so big, that when looking up to the overhead panel and not getting to click a button by the first try, if you look down, you’re always almost in the grass.

    The second issue: I believe the engines during taxiing produce too much idle thrust. If uncontrolled, an A320 easily goes up to over 35kts in no time.

    My wishes are simple: the plane should go straight if I don‘t do inputs when rolling (even on take off roll, unless the crosswind is the valid reason at speeds over 80kts, off course not when taxiing with only one engine) AND the when rolling on idle, the acceleration should be a little bit less powerful and not racing up to +35kts.

    Use the rudder slider. Slipstream effect is stronger at low speed when any compensating rudder offset is less effective and in the climb with low speed and more power applied to the propeller. In the cruise with less power and more speed the slipstream is often balanced out.

    Any other effects can be presumed to be authentic, it is a very good sim.

    I did a taxi test on the A320 and didn't notice anything wrong. Everything seems normal to me, and the plane never goes over 35 knots during taxiing unless I put a lot of power into the engines. It could be that you're not applying the correct power during taxiing or you're experiencing some sensitivity issues with the controls, which might be causing the plane to deviate from the taxiway. When testing the A320 during taxiing, I had to control the engine power to avoid excessively fast roll on the taxiway, and also control the rudder with subtle, light movements to prevent the plane from deviating to the left or right.

    Real world aircraft start rolling on idle thrust and can accelerate to quite some speed, too. Currently the aircraft in Aerofly FS are not very heavy though, just below max landing weight for the most part, so they could be 20% heavier in the real world which increases friction and that requires more thrust to get going. So that's somewhat realistic.

    As for drifting off sideways, please tell us which airport you are currently at and where exactly you taxi. Airports are sloped and if there is a sideways slope this could cause any plane to drift off the taxiway centerline.

    I guess this solves my drifting issue. Last Airport was HECA.

    About the speed: I think the sliders react a bit too hard for breaking. If I use the break e.g. 20-30% of the slider leads to a hard stop during taxiing. I know the slider for breaking is quite short, but the first half should only apply up to 20% breaking force and the other half should apply the other 80%, if you know what I mean. Even on iPad with more screen I should not drag my thumb down from idle to break, I kinda need to “roll” my thumb downwards to apply gentle breaking force. Same on landing. If using just a bit of the slider on the screen always decelerates the plane like an emergency stop.

    I’m not a programmer but maybe the slider when on the plane is on ground could have a more subtle effect on the brakes.

    At least for me, everything is working normally, both with the rudder control and the engine power control, and I haven't found any faults that would cause the plane to veer to the sides or have excessive speed during taxiing.

    I just find the brakes too powerful. I don’t veer to the left or right. But if I was in a real plane and the pilot brakes so heavily that it was noticeable from the planes suspension. I wouldn’t be happy as a passenger. I can’t seem to brake smoothly or subtly on my iPad.
