T-6A INSTRUMENT NAVIGATION

CHAPTER FOUR

405. STATION PASSAGE

Station passage is defined as the moment the aircraft passes directly over or abeam the radio

facility.

VOR station passage occurs when the TO-FROM indicator makes the first positive change to

FROM.

NOTE

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.

PROCEDURE

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.

NOTE

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.
