Wind Drift Correction
Techniques
You may have to
Abeam
compensate for two
different wind effects while
flying a correct holding
pattern--head/tail winds and
crosswinds. Head/tail
winds will only be a factor
on non-DME patterns, for
which you will have to
adjust the outbound leg for
a correct inbound time.
WIND
Compensate for crosswinds
Increase crab outbound for appropriate radial
in order to arrive at an
offset
outbound position from
which a turn inbound will
place the aircraft on the
holding course. This is
normally accomplished by
Abeam
WIND
utilizing a larger
(approximately two to three
times) drift correction on the
outbound leg.
See Figure 31.
Lost Communication
If communication is lost,
and the pilot has received
EFC time and the holding fix
Abeam
and initial approach fix (IAF)
0+45 sec
are the same, then leave
the fix at EFC time. If,
however, the holding fix and
1+00 min (1+30>14,000 MSL)
IAF are not the same, leave
the holding fix at EFC time
and proceed to initial
VOR: Adjust outbound leg for
approach fix. When EFC
WIND
proper inbound timing
has not been received,
continue on assigned route
and do not hold.
