 HOLD to a fix (HF)
This type of hold can only be found in
arrival/approach procedures.
It cannot be created by pilot; it is
automatically loaded with associated
procedure based on NAVdb
parameters.
Regardless of the hold entry, the A/C
overflies the hold entry fix twice:
− The first time when entering the
hold,
− The second time when leaving the
hold to begin the approach.
Guidance:
− If speed is managed, speed is
maintained as computed by the
FMGC.
− If NAV mode is engaged, A/C flies
the track as entered in the ACTIVE
F-PLN.
− If DES mode is engaged, A/C flies
profile as computed by the FMGC.
MCDU F-PLN page reflects computed
predictions.
The hold is automatically exited.
In the following example, RNAV
arrival at KMEM, a HOLD at BONTE
has been automatically selected.
A pseudo waypoint HOLD L BONTE is
displayed [line 4].
Reaching BONTE, A/C will enter in holding pattern to fly a 4 NM
outbound leg and then fly again BONTE.
Caution
If the pilot modifies any of the parameters of the holding pattern
(INB CRS, TURN, TIME/DIST), the hold becomes a hold with manual
termination and the automatic exit is no longer available.
