Flight Procedures
Instrument Flight
45-Degree Method
You will find this procedure useful when intercepting an outbound radial of a VOR or TACAN station that is
some distance away. As with the other intercept procedures, you must first ensure that the station is
properly tuned and identified and then dial in the desired course (radial) in the HSI course select window.
To determine the intercept heading, look from the tail of the bearing pointer used to the desired course
and 45 degrees beyond. Now turn to and maintain the intercept heading until you reach the lead point
(Figure 21).
