TACAN and VOR Procedures
T-45C TS, ADV, & IUT RIFP-02
7.
Fly straight short legs allowing head of the bearing
pointer to reposition between 5 and 10 degrees
behind wingtip position
8.
Turn aircraft to reposition the head of the bearing
pointer from behind to between 5 and 10 degrees
ahead of wingtip position
NOTE: Crosswind can make holding the DME
difficult. You may need to increase or decrease the
number of degrees the bearing pointer is placed
relative to the wingtip position to affect a wind
correction that will hold the aircraft on DME as the
aircraft moves around the arc. Refer to the ground
track marker for winddrift.
C.
Angle-of-bank method
NOTE: The angle-of-bank method is usually used when
the aircraft is within 12 miles DME of the station.
Although each method has been identified according to
DME limits, you can use either at any time.
1.
Tune and identify station
2.
Determine direction to turn
3.
Determine desired lead point (refer to LPC)
4.
Initiate turn when DME equals radius of arc plus or
minus desired lead
5.
When established on the arc, adjust angle of bank
(AOB) to maintain proper distance and keep the
pointer on HSI 90-degree benchmark (wingtip)
NOTE: Adjustments to the position of the head of
the bearing pointer will have to be made relative to
the 90-degree benchmark to compensate for the
position of the wind relative to the position of the
aircraft on the arc. Refer to the ground track marker
for wind drift.
