CLIMB AND DESCENT (CONT’D)
05 - TRAINEES’ ACTIONS
CLIMB
In the managed climb, the aircraft climbs with thrust levers set at the climb gate, producing
climb thrust, maintaining a speed/Mach number computed dependant on the cost index. The
higher the cost index, the higher the speed. Speed control is via elevator and will give
varying rates of climb to maintain a set speed.
A similar situation is true in OPEN CLB.
Selected speed may be used to increase/decrease climb rate, with thrust remaining at climb
power.
Be careful when leaving an altitude and selecting climb, that you allow the aircraft to begin
climbing with climb power before selecting a lower speed than target, or the aircraft may
reduce power initially to follow speed rather then beginning the climb. At all times, the aircraft
will try to maintain speed, thus if a lower speed is selected too quickly, thrust will be reduced
to achieve this. EXPEDITE (A320 only) is useful here, though take care not to remain in
EXPEDITE mode too long, as the target speed is green dot, and accelerating from green dot
to cruise speed at altitude takes a long time.
If a set rate of climb is required, V/S mode may be used. Be very careful to watch the speed
if high rates of climb are selected. Thrust will vary to maintain the speed and V/S. However, if
V/S is too great, speed will begin to decay, and care must be taken not to end up in a slow
speed, low energy situation.
If a low V/S is specified, thrust will vary to maintain both climb rate and the chosen speed.
On the ND, the top of climb point is displayed and can be monitored to comply with ATC or
other requirements. This point will be the level off point of the current selected altitude. The
FMGS however, will always give the top of climb point of the altitude specified in the F-PLAN
(shown on PROG page). Also useful is the PERF page, which will give predictions to the
selected altitude.
DESCENT
The descent may be in OPEN DES mode, managed DES mode or V/S.
In DES mode, the aircraft will calculate an ideal profile and will try to fly it. Its progress can be
monitored on the PROG and PERF pages. Speed varies to match the required descent path.
In OPEN DES, the thrust is at idle and a set speed is flown. Again, progress can be
monitored on both PROG and PERF pages.
In EXP DES (A320 only), the thrust is idle and the speed target is just short of Vmo/Mmo.
Very high rates of descent can be achieved and careful monitoring is vital.
Mentally checking that the aircraft will arrive at its descent windows is useful so that the
approach is not rushed, nor fuel burned needlessly.
