Fokker D.VII. Flying straight and level N. Wind 6m/s from the west. I have to keep constant right aileron pressure to keep from rolling left. Turn 180 degrees and go back straight and level S. Need to keep constant left aileron pressure. Weird. The amount of aileron pressure required is roughly inversely proportional to speed. Even weirder. I try to compensate with rudder, thinking I might have some horrible auto-rudder thing to keep the nose in the direction of flight, but no, kicking rudder causes major sideslip and speed loss.

My settings are without any flying aids (some visual aids, though.)

Flying pleasure gone, except in wind free conditions. Sigh.

This has been discussed before, hasn't it? Half a year ago or something?

Don't take this the wrong way but I thought there was always wind in here. That's why the wind sock is at the base. You did not say if you were on line or off. If on line you're at the mercy of the map builder as far as the wind goes. If you're off line check your settings maybe you had the wind set to blow and didn't catch it. I don't know if you fly in RL but I would LOVE a windless day! Crabbing to land feels strange no matter how much I do it!

Oh just re read what you posted..you knew the wind was on and its doing something strange..opps. I don't know I guess testing needs to be done. were you on line or off?

Although it has been said otherwise I read somewhere that wind could effect aircraft in flight.

First off, the fabric covering, as opposed to open struts, of the tail unit could cause weather cocking and secondly because the wing on the fuselage side downwind of the wind (does that make sense ?) was partially shielded can cause an imbalance of pressure from side to side.

Or at least something like that biggrin

@Damocles - I have enough RL flying hours to have an idea of what effects wind has on aircraft, and this is not one of them.

@Logan - offline. Beta career.

I just tried to replicate what Swingman was doing, in QMB I could only set the wind to 5ms. If the wind is out of the west are your flying north its blowing at your left to right so you should need left ron not right, if you turn 180 you should need right ron not left. So his is backward from what my test did. Very strange.

ok so my test was offline with QMB so maybe it is a bug in that one mission.

Actually, I should not need any aileron at all to keep wings level, but when flying with wind from the left, my nose should be pointing leftish from the path of flight (i.e., the plane should drift to the right.)

Should I want to keep the nose in the direction of flight, e.g. when strafing ground targets, I'd need left aileron and right rudder.

Right, That's kind of what I meant, your drifting right and would need left input to compensate for the right pull, not right. I wonder if the mission is written to say winds at the west when its really from the east? Could be a typo, maybe?

Ok here's some info, how relevant I don't know.

Lateral stability, instability etc
