Applicable to: ,
The pilot may define a new destination and insert it through the lateral revision page. The pilot may
then call up the new destination from any waypoint along the flight plan except the FROM waypoint,
the destination, and the missed-approach waypoint. When the new destination has been inserted,
a flight plan discontinuity appears between the revision waypoint and the new destination. All
waypoints beyond the revision waypoint (including the previous destination and associated missed
approach) are deleted.
SELECT the lateral revision function at an appropriate waypoint.
WRITE the new destination in the scratchpad.
Enter it in the brackets under NEW DEST
INSERT the temporary flight plan ([ 6R ] key), and complete the flight plan to the new destination.

HOLDING PATTERN
Applicable to: ,
GENERAL
Holding pattern description, associated guidance and flight crew procedures are put together in
this chapter.
The flight management and guidance computer (FMGC) has three types of holding pattern that the
pilot can use in a flight plan.
Applicable to: ,
HOLD TO FIX (HF)
The holding pattern is always part of an arrival or departure procedure. The aircraft flies it once
and then exits the holding pattern automatically at the fix. The predicted speed in the holding
pattern is the lowest of ICAO speed limit, max endurance speed, or any speed constraint.
Guidance to the fix in the holding pattern is similar to that on any leg of a flight plan. The HF
patterns are part of the navigation database and cannot be created by the crew.
Applicable to: ,
HOLD TO ALTITUDE (HA)
This type of holding pattern is also part of an arrival or departure procedure.
The aircraft flies the hold until it reaches the specified altitude. Then it exits the hold automatically
at the fix.
The predicted speed for the holding pattern is the lowest of the ICAO speed limits, the max
endurance speed or any speed constraint.
The size of the holding pattern is a function of the predicted speed.
Guidance in a hold to altitude (HA) is similar to that for any leg of a flight plan.
The HAs are in the navigation database as part of arrival or departure procedures and cannot be
created by the crew.

Applicable to:
HOLD WITH MANUAL TERMINATION (HM)
This type of holding pattern may be part of an arrival procedure, or the pilot may enter it at present
position or at any flight plan waypoint.
The pilot will use this type of holding pattern to comply with a defined procedure or a clearance
limit or to meet an operational need (such as losing altitude, holding for weather improvement, or
absorbing an ATC delay).
This type of holding pattern is exited under pilot decision and not automatically.
There are 3 types of HM, all are modifiable.

DATABASE HOLD
If the holding pattern is part of the database, it is named DATABASE HOLD and all its
associated data (inbound course, turn direction, time/distance) are defined in the data base.
Flight crew can modify this data.
COMPUTED HOLD AT ...
If the holding pattern is not in the database, the FMGC designs a holding pattern and proposes
it to the pilot. The associated data consists of default values that the pilot can modify.

HOLD AT ...
If the pilot inserts into the active flight plan a holding pattern that is manually corrected from a
hold defined by the FMGS, the screen displays a “HOLD AT ...” page. The field 2R displays
REVERT TO DATABASE or REVERT TO COMPUTED to restore the database data if
necessary.
PREDICTIONS AND GUIDANCE ASSOCIATED WITH AN HM HOLDING PATTERN (HOLD
WITH MANUAL TERMINATION)
Before deceleration
Although the hold is inserted into the flight plan, the FMGS does not take it into account for
predictions until the aircraft enters the hold.
However, if the hold is not deleted by the crew, the FMGS schedules a deceleration point and
