Instrument Flight
30-Degree Method
Once you have tuned the station and selected the desired course in the HSI course select window, look
from the desired course on the compass card to the head of the bearing pointer used and 30 degrees
beyond. The heading located 30 degrees beyond the bearing pointer is the heading you will fly to the
intercept. Turn the aircraft to this heading and maintain it until you reach the lead point and then complete
the intercept (Figure 18). You look from the desired course to the bearing pointer.
