DESCENT CONSTRAINTS
Applicable to: ALL
Descent constraints may be automatically included in the route as part of an arrival procedure or they
may be manually entered through the MCDU F-PLN page. The aircraft will attempt to meet these as
long as DES mode is being used.
The crew should be aware that an ATC "DIR TO" clearance automatically removes the requirement
to comply with the speed/altitude constraints assigned to the waypoints deleted from the F-PLN.
However, if intermediate waypoints are relevant, e.g. for terrain awareness, then "DIR TO" with
ABEAMS may be an appropriate selection as constraints can be re-entered into these waypoints if
required.
Following the selection of HDG, DES mode will switch automatically to V/S, and altitude constraints
will no longer be taken into account.

PREFACE
Applicable to: ALL
Whenever holding is anticipated, it is preferable to maintain cruise level and reduce speed to green
dot, with ATC clearance, to minimize the holding requirement. As a rule of thumb, a M 0.05 decrease
during one hour equates to 4 min hold. However, other operational constraints might make this
option inappropriate.
A holding pattern can be inserted at any point in the flight plan or may be included as part of the
STAR. In either case, the holding pattern can be modified by the crew.
HOLDING SPEED AND CONFIGURATION
Applicable to: ALL
If a hold is to be flown, provided NAV mode is engaged and the speed is managed, an automatic
speed reduction will occur to achieve the Maximum Endurance speed when entering the holding
pattern. The Maximum Endurance speed is approximatively equal to Green Dot (it can be between
Green Dot and Green Dot +10 kt, depending on aircraft weight and flight conditions) and provides the
lowest hourly fuel consumption.
If the Maximum Endurance speed is greater than the ICAO or state maximum holding speed, the
crew should select flap 1 below 20 000 ft and fly S speed. Fuel consumption will be increased when
holding in anything other than clean configuration and Maximum Endurance speed.
IN THE HOLDING PATTERN
Applicable to: ALL
The holding pattern is not included in the descent path computation since the FMGS does not know
how many patterns will be flown. When the holding fix is sequenced, the FMGS assumes that only
one holding pattern will be flown and updates predictions accordingly. Once in the holding pattern,
the VDEV indicates the vertical deviation between current aircraft altitude and the altitude at which
the aircraft should cross the exit fix in order to be on the descent profile.
The DES mode guides the aircraft down at –1000 fpm whilst in the holding pattern until reaching the
cleared altitude or altitude constraint.
When in the holding pattern, LAST EXIT UTC/FUEL information is displayed on the MCDU HOLD
page. These predictions are based upon the fuel policy requirements specified on the MCDU FUEL
PRED page with no extra fuel, assuming the aircraft will divert.
The crew should be aware that this information is computed with defined assumptions e.g.:
• Aircraft weight being equal to landing weight at primary destination
• Flight at FL 220 if distance to ALTN is less than 200 nm, otherwise FL 310 performed at maximum
range speed
• Constant wind (as entered in alternate field of the DES WIND page).

• Constant delta ISA (equal to delta ISA at primary destination)
• Airway distance for a company route, otherwise direct distance.
Alternate airport may be modified using the MCDU ALTN airport page which can be accessed by a
lateral revision at destination.
To exit the holding pattern, the crew should select either:
• IMM EXIT (The aircraft will return immediately to the hold fix, exit the holding pattern and resume
its navigation) or
• HDG if radar vectors or
• DIR TO if cleared to a waypoint.
