T-6A INSTRUMENT NAVIGATION
1. Determine the new course and set it in the CDI. Select the proper source for the CDI.
Your new course will be either:
The same as the new radial if intercepting outbound.
The reciprocal of the new radial if intercepting the new radial inbound.
2. Determine the present radial the aircraft is on by looking at the tail of the appropriate
3. Determine the location of the new radial relative to the tail of the bearing pointer (left or
Start a turn toward the new radial.
5. Stop the turn when the new course is under the first 45° benchmark in the top half of the
compass card. Note the heading.
1. The angle of intercept is the angular difference between the
heading of the aircraft (intercept heading) and the desired course.
The minimum acceptable angle of intercept for an inbound course
interception must be greater than the number of degrees the aircraft
is displaced from the desired course. The angle of intercept should
not exceed 90°.
2. To ensure you have the proper intercept established, ensure
the HEAD of the bearing pointer is in a position to FALL if flying
inbound, or the TAIL of the bearing pointer in a position to RISE
to the new course if flying outbound.
Maintain this intercept heading until the bearing pointer approaches the desired course.
7. Turn to intercept the course. Judge the rate of bearing pointer movement and plan your
turn so as to roll out on your new course.
Track on desired course.
Turning toward the new course vice radial.
Not doing steps 1-3 prior to beginning the turn.
