Over the Station Intercept

CHAPTER SIX

T-34C INSTRUMENTS

TACAN Due to the increased cone of confusion associated with TACAN stations,

station passage is noted when DME stops decreasing. When flying directly over the TACAN

station, the range indicator will stop decreasing when it indicates the approximate aircraft altitude

above the station in nautical miles (NM). For example, an aircraft flying at 30,000 feet over a

TACAN station at sea level will indicate station passage at 5 DME (6000 feet per 1 NM).

NOTE

Your instrument indications will fluctuate when close to the station;

this does not necessarily mean your aircraft is off course. Do not

chase either the VOR or TACAN needle when close to the station.

Limit your heading corrections to within 10 of drift corrected

heading when in close to avoid overshooting.

OVERTHESTATION INTERCEPT

Reference: NIFM Part V, "Station Passage."

Amplification An overthestation intercept is a procedure used to intercept and fly

outbound on a specific radial after station passage. In Radio Instrument Stage, the overthe

station intercept will be practiced as a distinct maneuver. In the "real world" the overthestation

intercept is normally performed as part of an overall maneuver such as an instrument approach or

Missed Approach, or while flying the airways.

Procedure Upon station passage, perform the following procedures: (6 Ts as appropriate).

TIME Note time of station passage; write it down.

TURN

Turn in the shortest direction toward the outbound course.

ii.

Roll out on a heading the same as the outbound course (parallel the new

course).

TIME As required.

TRANSITION As required.

TWIST Set the new course in the IND350.

Wait for the VOR or TACAN needle to settle down.

ii.

Note the number of degrees between the intended course and the tail of the

needle.
