TACAN/VOR Navigation Procedures, TACAN/VOR Holding
e. Connect two fixes with an imaginary line
f. Move line to center of compass card parallel to
original line and read course to the new fix off
compass card
g. Turn to new course (plus wind correction if known);
top of imaginary line where it crosses compass card
h. Update course and make corrections periodically to
point-to-point heading
C. Wind correction (crabbing) 2.7.5.1.8.2
NOTE: Tail winds and head winds affect ground speed
only.
1. Used to maintain radial/bearing via tracking into wind
(maintaining a constant track over the ground)
2. Crab angle (heading differential)
a. Correct: aircraft maintains desired course
b. Insufficient: aircraft continues to drift with wind
c. Too large: aircraft crosses radial
3. Procedure
a. Confirm drift due to crosswind by referencing CDI
b. Compensate by turning aircraft back to reintercept
your inbound radial
c. Maintain crab angle to keep CDI centered
COMMON ERROR: Making too small a correction
to return to the radial.
