VERTICAL PERFORMANCE PREDICTIONS
Applicable to: ALL
The MCDU PROG page provides the crew with the MAX REC ALT and with the OPT ALT information (See cruise section). This information is to be used to rapidly answer to ATC: "CAN YOU CLIMB TO FL XXX?"
The MCDU PERF CLB page provides predictions to a given FL in terms of time and distance assuming CLB mode. This FL is defaulted to the FCU target altitude or it may be manually inserted. The level arrow on the ND assumes the current AP engaged mode. This information is to be used to rapidly answer to ATC: "CAN YOU MAKE FL XXX by ZZZ waypoint?". The crew will use a PD (Place/ Distance), i.e. ZZZ,-10 waypoint if the question is "CAN YOU MAKE FL XXX , 10 nm before ZZZ point?"
LATERAL NAVIGATION
Applicable to: ALL
If the aircraft is following the programmed SID, the AP/FD should be in NAV. If ATC vectors the aircraft, HDG will be used until a time when clearance is given to either resume the SID or track direct to a specific waypoint. In either case, the crew must ensure that the waypoints are properly sequenced.
The crew should keep in mind that the use of HDG mode e.g. following ATC radar vectors, will revert CLB to OP CLB and any altitude constraints in the MCDU F-PLN page will not be observed unless they are selected on the FCU.

Once the cruise flight level displayed on the MCDU PROG page is reached, the cruise Mach number is targeted and cruise fuel consumption is optimized.

2 Applicable to: MSN 0344, 0486-4078
Once the cruise flight level is reached, "ALT CRZ" is displayed on the FMA. The cruise Mach number is targeted and cruise fuel consumption is optimized.
FMS USE
Criteria: SA

CRUISE FL
If the aircraft is cleared to a lower cruise flight level than the pre-planned cruise flight level displayed
on MCDU PROG page, the cruise Mach number will not be targeted. The crew will update the MCDU PROG page accordingly.
When at cruise FL, the AP altitude control is soft. This means that the AP will allow small altitude variation around the cruise altitude (typically ± 50 ft) to keep cruise Mach before a readjustment of thrust occurs. This optimizes the fuel consumption in cruise.
WIND AND TEMPERATURE
When reaching cruise FL, the crew will ensure that the wind and temperatures are correctly entered and the lateral and vertical F-PLN reflect the CFP. Wind entries should be made at waypoints when there is a difference of either 30 ° or 30 kt for the wind data and 5 °C for temperature deviation. This will ensure that the FMS fuel and time predictions are as accurate as possible.
