station

List

NOTE: The distance between radials at 60 nm from the

station is 1 nm and decreases/increases proportionally

to/from the station.

a. Chord method (usually used when greater than

12 miles DME from station)

(1) Tune and identify station

(2) Determine direction to turn

(3) Determine desired lead point

NOTE: Add lead when tracking to the station;

subtract lead when tracking from the station.

(4) Monitor bearing pointer and DME to determine roll-

out

COMMON ERROR: Not monitoring DME and

rolling out at the wrong time and on the wrong

DME arc.

(5) Fly a straight short leg, allowing head of bearing

pointer to reposition between 5 and 10 degrees

behind wingtip position

(6) Turn aircraft to reposition bearing pointer from

behind to between 5 and 10 degrees ahead of

wingtip position

(7) Continue sequence of alternating ahead/behind

wingtip until you turn inbound or outbound on

your new radial

b. AOB method (usually used when within 12 miles

DME of station)

(1) Tune and identify station
