Common Errors - P-8710052

CHAPTER FOUR

T-6A INSTRUMENT NAVIGATION

Note and report the fuel remaining on board.

Set NAVAIDs(as required):

Tune the proper frequency.

Identify the station with Morse Code.

Monitor as required.

Confirm the correct source for the bearing pointer and CDI.

Twist the proper course into the CDI.

7. Update navigation: Update your navigation on the airway or direct to the next point, as

appropriate. Wait for the VOR bearing pointer to settle down. Note the number of degrees

between the intended course and the tail of the bearing pointer. Turn that many degrees away

from the desired radial, up to a maximum of 45 beyond the outbound course. Maintain this

heading while the tail of the bearing pointer rises to the outbound course. As the tail of the

bearing pointer approaches the outbound course, turn to the wind-corrected course to maintain

the desired course and track outbound.

COMMON ERRORS

1. Not giving the instruments enough time to settle down before establishing angle of

intercept.

2. Drifting off or changing the intercept heading while the tail of the bearing pointer rises to

the outbound course. Hold the intercept heading until you can make one continuous turn rolling

out on course.

3. Not applying the correct lead point for turns greater than 90, over a NAVAID, onto an

airway.

Proceeding direct to the next point when filed on an airway, or vice versa.

407. RADIAL INTERCEPTS

A radial intercept is a procedure used to position the aircraft on a different radial. Radial

intercepts are performed to allow you to practice orienting yourself around a navigational facility

and are generally encountered in a teardrop or procedure turn approach. You may be outbound

or inbound on your present radial and be required to intercept a new radial either inbound or

outbound. Regardless of the situation, the same procedures are used for all radial intercepts of

30 or less.
