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.
