TACAN/VOR Navigation Procedures, TACAN/VOR Holding
g. Complete intercept
5. 45-degree outbound radial intercept
a. Tune and identify station
b. Set desired course in course selection window
c. Look from tail of the bearing pointer used to desired
course and 45 degrees beyond to determine
intercept heading
d. Turn aircraft to the intercept heading
e. Maintain intercept heading until lead point is reached
f. Complete intercept
COMMON ERROR: Looking from the desired
course to the tail of the No. 1 bearing pointer and 45
degrees beyond to determine the intercept heading.
B. TACAN 2.7.7.3.3.1
1. Lead point calculations (LPC)
Fig 1: Lead Point
Identifier
a. Approximately 1percent of ground speed for a 90-
degree intercept
NOTE: When ground speed is not available,
approximate this value using KIAS adjusted for wind.
b. Use a reasonable distance lead point for intercepts
of less than 90 degrees
2. Intercepting and maintaining a TACAN arc around a

station
List
NOTE: The distance between radials at 60 nm from the
station is 1 nm and decreases/increases proportionally
to/from the station.
