T-45C TS INav-05

TACAN/VOR Navigation and Holding Procedures

REFRESHER

The T-45C HSI takes the place of the RMI, CDI, and RNAV

remote display indicators of the T-34C.

Because the T-45C cruises about three times as fast as the

T-34C, you have a third of the time to anticipate changes.

Lead point calculation (LPC) is the distance, in nautical miles

or radials, that you must start (lead) a turn in advance of

intercepting a new course, radial, or arc. Your lead point

calculation must recognize both the aircraft’s speed and

distance from the station. Distance between radials

decreases proportionally as you head towards the VOR/

TACAN station and increases proportionally as you head

away from the station.

The T-45C requires more distance to turn than does the

T-34C.

Holding is performed at max endurance airspeed.
