FCTM 2022 Flashcards
to further reduce potential odors in the Cabin, the APU Bleed may be selected
3 minutes after APU start. This APU warm-up time enables the seals to reach their optimum performance and eliminates oil traces in the APU airduct.
FMGS prep: The trip wind facility is available if
the wind profile has not already been entered
The PM performs this check via a check of the different FMGS pages, in the same order
as the FMGS preparation
The maximum brake temperature limitation for takeoff ensures that, in the case of a hydraulic leak,
any hydraulic fluid that touches the brake units does not ignite in the wheel well after the landing gear retraction.
If the ACCU PRESS drops below 1 500 PSI, the flight crew should be aware that the Parking Brake can, quite suddenly, become less efficient. If the flight crew encounters any braking problems during taxi, they should set
the A/SKID & N/W STRG sw to OFF. They should not apply pressure to the pedals while setting the A/SKID & N/W STRG sw to OFF. Then, the PF should refer to the triple brake indicator and modulate the pressure as necessary.
Brake fans should not be used during takeoff, in order to
avoid Foreign Object Damage to fans and brakes.
The flight crew should be aware that the main gear on the inside of a turn will always cut the corner and track inside of the nosewheel track. For this reason, the oversteering technique may be considered especially for A321 where main gear
is 20 m behind the pilot.
If the takeoff has to be achieved without air bleed fed from the engines for performance reasons, but air conditioning desired, the
APU bleed may be used with packs ON, thus maintaining engine performance level and passenger comfort.
In case of APU auto shut down during takeoff, the engine thrust is
frozen till the thrust is manually reduced. The packs revert to engine bleed which causes an increase of EGT to keep N1/EPR.
If the takeoff is performed with one pack unserviceable, the procedure states to set the failed pack to OFF. The takeoff may be performed with the other pack ON (if performances permit) with TOGA or FLEX thrust, the pack being supplied by
the onside bleed. In this asymmetric bleed configuration, the N1 takeoff value is limited to the value corresponding to the bleed ON configuration and takeoff performance must be computed accordingly.
Tail strikes most often occur in such adverse conditions as
crosswind, turbulence, windshear, etc.
When performance is limiting the takeoff weight, the flight crew uses TOGA thrust and selects
the configuration that provides the highest takeoff weight.
the flight crew selects the configuration that provides the maximum FLEX temperature This is done to
prolong engine life. The first degrees of flexible thrust have an impact on maintenance costs about 5 times higher than the last one.
the tail clearance at lift off depends on the configuration. The highest flap configuration gives the highest
tailstrike margin.
The main purpose of the pitch trim setting for take-off is
to provide consistent rotation characteristics.
Crosswind takeoff- direct effect of the reduction in lift due to the extension of the spoilers on one wing will be
a reduction in tail clearance and an increased risk of tailstrike.
Acceleration altitude: The speed target jumps: • Either to
the managed target speed e.g. speed constraint, speed limit or ECON climb speed • Or to the preselected climb speed (entered by the pilot on the MCDU PERF CLB page before takeoff).
THE ALPHA LOCK FUNCTION The slats alpha/speed lock function will prevent slat retraction at high AOA or low speed at the moment the flap lever is moved from Flaps 1 to Flaps 0. “A. LOCK” pulses above the E/WD Slat indication. The inhibition is removed and the slats retract when both
alpha and speed fall within normal values. This is a normal situation for take-off at heavy weight. If Alpha lock function is triggered, the crew will continue the scheduled acceleration, allowing further slats retraction.
during Slats/Flaps transition, the dynamic acceleration of the airplane may lead to a temporary OVERSPEED WARNING even if the current speed is
out of the red and black strip displayed on the PFD. In this situation, there are no operational consequences. The flight crew must report any type of overspeed event.
If the aircraft is required to level off below the acceleration altitude, ALT* engages and target speed goes to
initial climb speed
Noise abaitment 1 - less noise closer to airport- V2+10 to 20kt- maintain reduced
Power and slats and flaps in takeoff configuration
Noise abaitment 2 - far from airport- when flaps/slats are retracted (3 things):
Positive rate of climb, reduce power and climb at S speed + 10kt to 20kt
If the crew selects a high V/S, it may happen that the aircraft is unable to climb with this high V/S and to maintain the target speed with Max Climb thrust, for performance reasons. In that case, the AP/FD will guide to the target V/S, and the A/THR will command up to Max Climb thrust, in order to try to keep the target speed; but the aircraft will decelerate and its speed might reach
VLS. When VLS is reached the AP will pitch the aircraft down so as to fly a V/S, which allows maintaining VLS. A triple click is generated.
The managed climb speed, computed by the FMGS, provides the most economical climb profile as it takes into account
weight, actual and predicted winds, ISA deviation and Cost Index (CI). The managed climb speed also takes into account any speed constraints, e.g. the default speed limit which is 250 kt up to 10 000 ft.
The speed to achieve the maximum rate of climb, i.e. to reach a given altitude in the shortest time, lies between
ECON climb speed and green dot
The speed to achieve the maximum gradient of climb, i.e. to reach a given altitude in a shortest distance, is
green dot.
the FMS Go-Around phase may be unduly activated after takeoff if the aircraft is above the ACC ALT and the flight crew sets the thrust levers to TOGA detent with at least CONF 1. the flight crew should do either of the following in order to activate the CLIMB phase:
‐ Insert a NEW DEST (different from the current DEST), or ‐ Select the ALTN destination.
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.
it is recommended to insert the same wind at current FL as the one at
Step climb. This is due to wind propagation rules, which might affect the optimum FL computation.
The DATA/Stored Routes function in the MCDU can be used to store up to.
five possible diversion routes
If ATC requires a report on a given radial, the crew will use the
FIX INFO page or RADIAL FIX INFO page which can be accessed from a lateral revision on F-PLN page at PPOS.
The Cost Index (CI) is used to take into account the relationship between
fuel and time related costs in order to minimize the trip cost. CI=0 corresponds to maximum range whereas the CI=999 corresponds to minimum time.
