T-6A INSTRUMENT NAVIGATION
405. STATION PASSAGE
Station passage is defined as the moment the aircraft passes directly over or abeam the radio
VOR station passage occurs when the TO-FROM indicator makes the first positive change to
The head of the VOR bearing pointer may fall below the 90°
benchmark at the same time. If the CDI is unavailable, this may be
used as an indication of station passage.
406. OVER-THE-STATION INTERCEPT
An over-the-station intercept is a procedure used to intercept and fly outbound on a specific
radial after station passage. This procedure applies to over-the-station intercepts following
station passage. Over-the-station intercept is normally performed as part of an overall maneuver
such as an instrument approach or missed approach, or while flying the airways. The procedure
described here applies to the enroute phase of training where you are flying on airways or joining
airways after completing a direct leg of flight.
If you are joining an airway or remaining on an airway over a NAVAID, and the turn exceeds
30°, lead the turn by 1/2° of 1% of your GS in KIAS, plus minimum DME.
IAW the AIM and the FAA, the intent of leading the turn is to
remain within the airway structure. At the true airspeeds we fly in
the T-6A, you normally will not exceed this distance. This
formula helps ensure you remain within 4 NM of the airway
centerline when accomplishing large turns.
Upon station passage, perform the MOT actions:
Note and write down time of station passage.
2. Clear the turn and direct the IP to turn in the shortest direction toward the outbound course.
Roll out on a pre-calculated wind-corrected heading.
Report the time of station passage.
Report the aircraft position.
