Er, make that CDI.

Thks is an idea I disagree with. The rotatable azimuth is there for a reason
and should be used. The problem comes when the instrument student tries to
adjust the bezel for every heading change. A better method is to estimate
how much heading change into the wind is necessary in order to offset wind
drift and set the bezel to that heading...maybe five to ten degrees away
from the published course...and then work at maintaining that estimated
heading until it is proven wrong by moving either further into the wind or
back toward the nose. Whatever. Change the bezel a couple of degrees in the
necessary direction and go back to work on maintaining the heading using the
DG. Shouldn't have to touch the rotatable azimuth more than a couple of
times during an approach, if you are any good at guessing crosswind
component.

Better yet, relegate ADF to the museum of 20th Century aviation
artifacts. ;-)

Even better, get an RMI either mechanical or electronic.
