A student who's actually sat in an aircraft and carried out the pre-flight
should have little doubt as to what moving the trim wheel actually does.

In the Warrior I fly, we're taught to put in full back elevator, then wind
the trim through the limits of its travel, watching the trim tab to ensure
it moves as it should.

Similarly, in the 'Aircraft General and Principles of Flight' exam we have
to sit in the UK, the operation of trim is expected to be understood.

That's interesting. How do you see the trim tab fromm the cockpit?

I've been in Tomahawk and DA-20. I did preflight on DA-20, but didn't
test trim.

Umm...you move your head?

On a PA28, the trim tab runs most of the length of the moving tailplane.
Pull the yoke back with your left hand, look over your left shoulder and
move the trim wheel through the extent of its travel with you right hand and
watch what happens.

Then you didn't do the pre-flight correctly.
