TACAN and VOR Procedures
T-45C TS, ADV, & IUT RIFP-02
(1) Degrees to turn outbound are equal to 90
minus the number of lead radials
determined by formula
(2) Degrees to turn inbound are equal to 90
plus the number of lead radials determined
by formula
(3) As a rule of thumb, reduce or increase the
lead radials determined by formula by one-
third
2.
Radial to arc intercept
a.
When intercepting an arc from a heading
significantly more or less than 90 degrees from
the arc, an adjustment should be made to the
result of the formula for arc intercepts
(1) Use 1% for a turn of approximately 90
degrees
(2) For a turn of approximately 45 degrees, use
1/3 of that required for 90 degrees
(3) For a turn of approximately 60 degrees, use
2/3 of that required for 90 degrees
(4) For turns of less than 30 degrees, very little
lead is required
b.
When intercepting an arc from a radial closer
than approximately 12 DME, an adjustment
should be made to compensate for outbound
turns greater than, and inbound turns less than
90 degrees
(1) Outbound radial to arc, add approximately
1/2 DME to 1% ground speed
(2) Inbound radial to arc, subtract
approximately 1/2 DME to 1% ground
speed
