Double Angle Off The Bow Method
As with the 30-degree method, begin this intercept by tuning the station and setting the desired inbound
course in the course select window. Now look from the desired course on the compass card to the head
of the bearing pointer used and an equal number of degrees beyond . The heading located an equal
number of degrees beyond the head of the bearing pointer is the heading you will fly to the intercept (max
45 degrees). Turn the aircraft to this heading and maintain it until you reach the lead point and then
complete the intercept (Figure 19). You look from the desired course to the head of the bearing pointer.

Outbound Intercepts
You can intercept a radial outbound from a station either when you fly directly to a station and then pick up
an outbound radial immediately after passing the station or when you intercept an outbound radial at some
distance from the station. The two outbound intercept procedures discussed here will address each of
these situations.
