procedure.
11. The PFD display advises the operator when to turn the aircraft, when to stop, and when to turn
again.
12. Upon instruction to turn, taxi the aircraft in a right turn. After approximately 25° to 30° of turn
from the last heading, the PFD display advises the operator to stop the aircraft.
Due to the difficulties in executing smooth, accurate turns the PFD may incorrectly
interpret a station and instruct to "HOLD POSITION" prior to full completion of a
30° turn. If this scenario is encountered, it is best for the operator to ignore the
"HOLD POSITION" command and instead use outside references to complete the
approximate 30° turn. Instead of using the PFD instruction to turn as a real-time
indication of when to turn, simply judge the 30° (±5°) turn increments of the aircraft
by using the compass rose radials. Dwelling at these 30° increments for the time
recommended by the PFD should result in successful calibration.
13. The PFD guides the operator to dwell at multiple headings around a complete circle.
