FCTM Holding
IN.THE.HOLDING.PATTERN
As the number of holding patterns to be flown cannot be inserted in the FMGS, the hold distance is not included in the descent path computation. After the holding fix is sequenced, the FMGS assumes that only the current 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 to be on the descent path. In DES mode, the aircraft descends at 1000 ft/min whilst in the holding pattern until reaching either the cleared altitude or altitude constraint. To exit the holding pattern, select IMM EXIT. The aircraft will return directly to the holding fix and continue with the FLT PLN. On leaving the hold, the speed will revert to managed descent speed. Selected speed may be required to avoid an undesired acceleration.
In the holding pattern, LAST EXIT UTC/FUEL information is displayed on the HOLD page. These predictions are based on the fuel policy requirements specified on the FUEL PRED page with no allowance for extra fuel assuming the aircraft will divert following a missed approach. This information is computed with defined assumptions, e.g. diversion routeing, flight level, Mach number and wind. Deviation from these assumptions may affect the arrival fuel at the diversion airport.
ADVERSE.WEATHER
The most common adverse weather encountered whilst holding is icing. When holding in icing conditions, maintain clean configuration whenever possible. Use of.engine.anti-ice.and.total.anti-ice.increases.fuel.consumption.as.follows:
FCOM.3.05 Engine.anti-ice Total.anti-ice
A333 +.1.5% +.3.5%
A343 +.4% +.5.5%
A346 +.1% +.4%
Procedural
FCTM REV.1.(6.JUN.05)
PROCEDURE.TURNS
Procedure turns must be flown using selected modes. On some approaches the procedure turn must be completed within specified limits. The turn size is determined by the ground speed at which the fix is crossed. If the fix is crossed at an excessively high ground speed, the procedure turn protected airspace may be exceeded. Initiate the turn at Green Dot and time for 1 min 15 sec from the start of the turn. Select Flaps 1 when turning inbound. Monitor the track to ensure the aircraft remains within the protected airspace. The published procedure.turn.altitudes.are.minimum.altitudes.
PROCEDURAL.APPROACHES
The detailed requirements for procedural approaches are laid down in PANSOPs..AERAD.Guide.refers.
TRACK.ESTABLISHMENT
Outbound descent may be commenced immediately following station or fix passage. Conversely, inbound descent may only be commenced when established.within.5. of.the.published.track.

FCTM REV 1 (6 JUN 05)
PREFACE
This section covers general information applicable to all approach types. Techniques which apply to specific approach types are covered later in the chapter.
During the approach phase, the aircraft may be operating at or below MSA, often in adverse weather in a high workload environment. Although ATC may be providing radar vectors to the initial or final approach fix, maintaining good situational awareness during the approach is essential.
NAVIGATION ACCURACY
If GPS PRIMARY is not available, a navigation accuracy check is to be carried out prior to any approach. The navigation accuracy status determines:
.
Which AP/FD modes are to be used.
.
The non precision approach strategy (guidance modes).
