Trim doesn't do anything to the nose-right/left of the airplane (yaw).

Trim is used to keep the airplane in level flight (pitch). However, you don't FLY the airplane with the trim wheel.

Rather, you use the trim to just keep the nose level.

Check out the lessons in 2k2, you could learn gobs! Wink

*cough*
ever heard of the aileron and rudder trim functions of an airplane Wink

What you talk about is the stabilizer trim (more known as just 'trim'...dont ask me why, I'm not english, lol)).

In case of an engine loss, you should use rudder trim to get proper roll controll of the airplane, for example

On Boeings, the aileron and rudder trim tabs/knob are located on the center piedestal, on the far back.

Now let's see. If you are drifting to the right you have a wind from the left. So to get the plane to fly in a straight line you need to trim in left rudder bringing the nose of the aircraft more towards the direction the wind is coming from.

When you do this it may affect your level wing attitude and you will need to apply elevator trim as well.

Remember to put everything back where it was or in an appropriate position for landing!!

It's good fun learning how to get it just right

Cheers

Yes, rudder trim is a legitimate point, however when most people refer to trim, they are in fact referring to elevator trim, and not rudder trim.

If a pilot is talking about trimming the aircraft, 9 times out of 10 it's elevator trim.

When they're talking about rudder trim, they'll specifically say so. Wink

Just so but the subject was a right hand drift off course. The other thing to remember is that if you are using autopilot the thing will correct itself anyway to a certain degree.
In the past I have had to do constant regular corrections after downloading winds aloft.
And always remember nothing is perfect in flying(although the day I went up in a R22 was near it!)
