The "trim tab" trims the aircraft for level flight. Say you're flying a 182 and have to hold a bit of back pressure to keep the plane
from descending. You simply "dial in" a bit of NOSE UP with the trim "wheel" located to the right of your right leg about mid way
down. See the pic. One trims an aircraft in three dimensions, it's a balancing act but becomes second nature pretty quickly. The
trim wheel pictured is for the elevator. To the right is the one for the rudder. On some aircraft, the entire elevator gets trimmed
with the trim wheel.....no trim tab. On RC planes, we trim with the trim switches located adjacent to the corresponding stick.
