Phases Of Flight

Question 1

Preflight

Answer 1

There is no optimum speed. SRS mode engaged or ground speed >90 knots

Question 2

Takeoff

Answer 2

Speed profile for 2 engines =V2+10 1engine= V2 or AC SPD
At acceleration altitude or by engagement of another vertical mode

Question 3

Climb

Answer 3

Speed profile is ECON CLB SPD/MACH
Reaching programmed cruise altitude

Question 4

Cruise

Answer 4

commanded Speed profile is ECON CRZ - MACH/SPD

<200 NM from DEST and any descent is initiated, or

> 200 NM from DEST and any descent is initiated with one of the following
-T/D reached
-FCU ALT set at or below:
‘FL 200 or
‘First altitude constraint (or lower) on the arrival

Question 5

Descend

Answer 5

commanded Speed profile is ECON DES - MACH or SPD
-Overflying (DECEL) pseudo waypoint with NAV (or LOC*/LOC) mode engaged and altitude <9500 ft AGL or -manual activation of the approach

Question 6

Approach

Answer 6

Speed profile is GDOT, S, F (depending on flap position) VAPP (when in final flap setting).

-Go around: when trust levers at TOGA detect and FLAPS lever not zero(if not in takeoff phase) or
-done: 30 seconds after landing or
-climb: when inserting a new CRZ FL

Question 7

Go around

Answer 7

Speed profile is VAPP or current speed, whichever is greater. Green dot at acceleration altitude.
-Approach: Manual activation of the phase or
-when above the acceleration altitude, manually switch to climb/cruise phase by using one of the following methods:
/if diverting to the programmed alternate on INIT A
/if diverting to any other alternate
/if go around phase was inadvertent
(There is more)

Question 8

Done

Answer 8

No speed profile

To preflight when INIT or PERF key is pressed
