The trick is that they have to learn new references for pitch, bank, and heading.

Have them start with one axis at a time...the Frasca should be able to selectively freeze them.

Freeze everything else, then let them practice bank with the TC. Repeat for pitch and heading.

Once they have that down, add a second axis, and then all three.

HOPEFULLY they already know VOR nav and are not GPS-babies.

For the mag compass, make sure they memorize the corrections...if they can't recite those cold they will not be able to use a mag compass for heading control.
