The flight crew cannot enter altitude and speed constraints at the hold exit‐ fix (this is only
allowed at the hold entry fix).
The vertical guidance in the HM during the descent phase calls for a constant‐
-1 000 ft/min, but the computer considers altitude constraints that will take effect farther
down the flight path as it calculates vertical guidance and predictions. The system will not
allow the aircraft to descend below the next altitude constraint. If the aircraft reaches the
next altitude constraint, it will level off, and the altitude constraint mode will engage.
With RESUME HOLD pressed
If the flight crew presses the key next to “RESUME HOLD”, the aircraft remains in the holding
pattern, and the display again shows “IMM EXIT”.
After that, each time the aircraft flies over the holding fix, the system updates the predictions
for one more holding circuit.
HOLDING PATTERN ENTRIES
The FMGS offers three types of entry into holding patterns :
1. Direct entry
2. Teardrop entry
3. Parallel entry

Note: If the leg the aircraft is flying toward the holding fix is on a “limit” between a teardrop
entry and a parallel entry, the FMGC may compute and display either of the two
entries. The pilot should keep this in mind and not assume that the FMGC is
malfunctioning.
If the flight plan leg toward the hold entry fix is on a course that is the reciprocal of
the inbound course of the holding pattern, the aircraft will fly a parallel entry.
Applicable to: ,
PROCEDURE TO INSERT A HOLD
The HOLD prompt enables the crew to enter a holding pattern, with manual termination (HM), at
the revised waypoint or at the present position.
The flight crew accesses the HOLD page from a lateral revision at the present position (PPOS) or
at a waypoint.
SELECT lateral revision at present position (PPOS), or at an applicable waypoint.
PRESS the HOLD prompt [3L].
CHECK and (if necessary) MODIFY the HOLD data

Applicable to: ,
PROCEDURE TO DELETE A HOLD (HOLD WITH MANUAL TERMINATION)
CLEAR the HOLD directly in the flight plan as can be done for a normal waypoint.
OFFSET
Applicable to: ,
GENERAL
The OFFSET prompt enables the crew to define a lateral offset to the left or right of the active
flight plan. Once inserted, the offset applies from the present position (PPOS) all along the flight
plan to the first waypoint (WPT) at which a holding pattern is defined, or to the last waypoint before
the runway. In most cases, the crew will use it en-route, because of an ATC clearance, or to avoid
bad weather expected along the flight plan route.
Accessed from lateral revision (LAT REV) at the present position page, an offset may be defined
between 1 and 50 nm in one-nautical-mile steps.
After inserting the offset in the flight plan, the flight plan page shows OFST in its title, and the
navigation display shows the offset flight plan in a solid green line and the original flight plan in a
dashed green line.
The offset is cleared :
Automatically (holding pattern, approach), or‐
Manually with the clear (CLR) key.‐
Note: If the crew enters an OFFSET when the aircraft is too close to the ending offset
waypoint, the FMGS may refuse to accept it, in which case the MCDU displays the
“ENTRY OUT OF RANGE” message.

INSERTING AN OFFSET
SELECT LAT REV at the present position (PPOS)
WRITE the required offset value and direction (for example, L5 or 5L).
PRESS [2L] to enter the offset into the OFFSET field.
PRESS [6R] to activate the OFFSET.
