Bearings: Fixing Position
Trainee pilots have to to learn to cope when the unexpected
happens. If their navigation equipment fails they can quickly find
their position by calling controllers at two different airfields for
a bearing. The two bearings will tell the pilot where he is. The
initial call on the controllers radio frequency will trigger a line on
the radar screen showing the bearing of the calling aircraft.
