RESUME HOLD
HOLDING PATTERN SIZE
The FMS is designed to keep the aircraft within protected airspace
during holding patterns. When the aircraft approaches a holding pattern
at a ground speed resulting in the aircraft exceeding protected airspace,
the scratchpad message HIGH HOLDING GRD SPD (ground speed)
is displayed 30 seconds before the aircraft crosses the holding fix.
When this message is displayed, the ground speed must be reduced
and the aircraft position, relative to the holding pattern, must be
monitored. When the high ground speed is maintained, the aircraft can
overshoot the outbound leg and possibly exceed protected airspace.
HOLDING PATTERN COURSE REVERSALS
Holding patterns that are part of the approach transition are used to
reverse the aircraft course and align the aircraft near the final approach
course. These procedures are only available from approaches in the
navigation database.
The procedure is to exit after entering the holding pattern. For both
teardrop and parallel entries, the FMS automatically changes to exit
hold at the beginning of the entry. For direct entries, the FMS
automatically changes to exit hold at the turn inbound to the hold fix. In
both cases, the pilot resumes holding at any time before exiting the
holding pattern. When holding is resumed, exiting the holding pattern
requires pilot action.
