What does ACTIVATE/CONFIRM APPR phase do for the pilot?

Back 8

• Allows thrust and speed target to follow a predetermined schedule, based on flap selection: o F0 = green dot

o F1 = S speed

o F2 = F speed

o F3 = F speed or VAPP (depending on landing flap selection)

o F4 = VAPP

• If using managed speed, GSMINI is available. If using selected speed, GSMINI is not available.

Front 9

Back 13

Dual mode, with one FMGS as master and the other FMGS as slave

Front 14

How does autopilot selection influence master FMGS logic?

Back 14

• If one autopilot is engaged, the respective FMGS is master

• If both autopilots are engaged, FMGS 1 will be the master

• If no autopilot is engaged FMGS 1 is the master

Front 15

If an amber OFF SIDE FM CONTROL message is displayed on the ND what action should the crew take?

Back 15

An FMGS has failed and both NDs must be set to the same mode and range. The full procedure can be found in the COM.

Front 16

In cruise flight with AP1 engaged, what would happen if AP2 was selected?

Back 24

Immediate go-around

Front 25

Explain the side stick operation and the associated glare shield SIDE STICK PRIORITY light.

Back 25

• Normally only one side stick should be operated at any given time.

• Should there be dual inputs, an aural "DUAL INPUT" will be annunciated over the speaker and the SIDE STICK PRIORITY green CAPT and F/O lights will flash. Side stick inputs are algebraically summed.

• Any time a pilot monitoring has to assume control, it MUST be verbally annunciated ("I HAVE CONTROL"). If necessary, the pilot taking over may need to press and hold the takeover pushbutton.

• If the pilot previously flying does not relinquish control (or if there is a malfunction present), the side stick can be rendered inoperative by holding the takeover push button for 40 seconds. An aural alert "PRIORITY LEFT (RIGHT)" will be annunciated over the speaker and the SIDE STICK PRIORITY red arrow light will illuminate in front of the pilot losing authority.

• The pilot having lost side stick authority can regain it by momentarily pressing the takeover pushbutton.

Front 26

• Appears when the aircraft is in the clean configuration

• Corresponds to the best lift-to-drag ratio

Front 41

What is Ground Speed Mini (GSMINI)?

Back 41

• Based on a calculated groundspeed at the runway

• Protects against actual groundspeed dropping below this calculated groundspeed

Front 42

What does it mean if the magenta target airspeed triangle is above VAPP on the approach?

Back 42

GSMINI has increased speed due to a higher headwind component at the present location.

Front 43

What are the 3 key factors in the GSMINI Calculations?

Back 43

• TWR wind = the MAG WIND entered in the PERF approach page (no gusts)

• TWR headwind component = the component of the MAG WIND projected on the runway axis (landing runway entered in the flight plan).

• Current Headwind Component = the actual wind measured by ADIRS is projected on the aircraft axis to define the current headwind component. The current headwind component is used to compute the variable speed target during final (IAS target).
