PRESS [ 1L ].
SELECT the ABEAM prompt : The system computes the radial, time, distance to go, altitude and
predictions related to the waypoint abeam the reference fix.
SELECT [5L ] to insert the abeam intercept waypoint into the flight plan : The system automatically
assigns its identifier as AB, followed by the first five characters of the reference fix identifier
(Example ABXYZ).

INSERTING A NEW DESTINATION
Applicable to:
The pilot may define a new destination and insert it via 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
This section describes holding patterns, associated guidance and flight crew procedures.
The Flight Management and Guidance Computer (FMGC) has three types of holding patterns that
the pilot can use in a flight plan.
HOLD TO FIX (HF)
The holding pattern is always part of an arrival or departure procedure. The aircraft flies it once
and then automatically exits the holding pattern at the fix. The predicted speed in the holding
pattern is the lowest of the 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.
HOLD TO ALTITUDE (HA)
The aircraft flies the hold until it reaches the specified altitude. Then, it automatically exits the hold
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 the arrival or departure procedures, and cannot
be created by the crew.

HOLD WITH MANUAL TERMINATION (HM)
This type of holding pattern may be part of an arrival procedure, or the pilot may enter it at the
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 according to the pilot's decision, 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 database. The
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.
