pressure to keep the airplane moving straight ahead (keep its heading constant), as shown in Figure

evator, aileron and rudder trim, then you’ll trim the elevator first, rudder next, followed by aileron
trim last.
Leveling Off From a Climb
No doubt there’s a country western song with an aviation theme titled, I’m High Over You Because
I’ve Been Climbing Forever. In the real world, you can’t climb forever. Eventually, you climb to a
specific altitude and then level off.
Beginning the Level Off To do so, you use the same principle of A+P=P. Keeping
in mind that the airplane is a large piece of machinery

goal is a graceful transition for you and your
passengers, you need to start leveling off be-
fore you reach the final altitude. This is called

The general rule for leveling off is to take

a 50-foot lead for leveling off works just fine. That’s what I do in small airplanes. I wait until I’m
within 50 feet of the correct altitude, then apply slight forward pressure, timing this properly to stop
the altimeter needle at the target altitude. It really doesn’t take

forward pressure on the yoke. Since your

speed, you should leave the throttle set at full
