What is detrimental aileron steer

Airplane with banner on a windy day

Aside from User58220's answer, I read a lot of nonsense here.

If you're flying an airplane (me and a lot of the other people on this website), when you're flying in mid-air, center the rudder.

The aircraft is not aware of the movement of the air mass over the ground (wind). The aircraft has a vertical stabilizer (tail) that causes it to point in its relative wind, which is completely independent of the movement of the air mass over the ground. If it draws a banner, it also flows in line with the plane.

As you deflect the rudder pedals, the tail of the aircraft is pushed left or right, causing the relative wind to blow harder against one side of the aircraft. They don't do this to balance the wind above the ground (except during landing and take-off when you don't have a banner).

The rudder is used alternately to compensate for adverse aileron yaw, during takeoff to compensate for asymmetrical propeller thrust, and during landing to keep the nose aligned with the runway in crosswinds.

If you do anything with the rudder while driving, do not do so to compensate for air movement over the ground.

EDIT: Adding some tutorial videos:

Crosswind landing technique.

More than you wanted to know about banner towing.

Better late than never: suppose the air mass just isn't moving, but the ground below is moving (in relation to the air). The plane just flies in the still air, with the banner and everything, no matter what the ground is doing.

However, if there is a need to fly from Airport A to Airport B, as pointed out by User58220, then it is a Navigation problem and not a problem in aircraft operations. It is necessary to turn the aircraft in a direction that will arrive at the place where Airport B is located when both the aircraft and the airport arrive there. This is called Wind triangle problem and there is a simple tool to solve it called E6B is designated .

Further edit: I almost forgot that when I started using Microsoft Flight Simulator the plane wasn't going where I showed it, which made landing very difficult. It would always drift out of the middle. I later learned a fundamental difference between cars and airplanes. Cars go where they show. Planes go where they go be worn . There is always some kind of wind. So when you get where you want to go look at the Floor to to see where you are being carried. When you are to the right of where you want to go, adjust your heading to the left and vice versa. You do this No way by aiming the aircraft at your destination, except in the general sense. I only mention this because the lack of this understanding could have led to the question of the OP.


For the sake of clarity, the term "cross wind" only refers to an angle between the actual wind direction and the ground track and Not at an angle between the relative wind and the plane's axis?

@ User58220: You got it.

Keep these thoughts

@MikeDunlavey With your last analogy you seem to be entering somewhat difficult territory. The reason is that this is analogy also for the Acceleration of the Soil instead of the Speeding up the Air works. That would be tedious. (I'm having a little trouble phrasing this idea, but I hope you get my point. Please confirm.) But for constant velocity air / ground, it's fine (of course).

@aufkag: Generally you assume that the winds you get from a Get wind forecast . If your route is long enough to make changes, resolve it by breaking the route into shorter "sections". It's not a very precise science.

Keep these thoughts

@ MikeDunlavey That's not my point. The moving ground analogy will not physically work if the movement is not a constant speed. It can be the nonsense invite, that you found on this page. Because then suddenly the momentum is relevant.
