Autoflight

Question 1

What is Alpha floor protection?

Answer 1

FCOM auto flight flight augmentation
Automatically sets TOGA thrust if the aircraft reaches a very high angle of attack.
Generated by the FAC and active from take off to 100ft RA on approach.
Alpha floor is lost in alternate or direct law and one engine out with slats/flaps extended.

Question 2

What is the Low-Energy aural alert?

Answer 2

FCOM autoflight flight augmentation
SPEED SPEED SPEED every 5s when aircraft energy level is going below a FAC calculated threshold.
Available Conf 2-full

Question 3

What is the Windshear detection function?

Answer 3

FCOM autoflight flight augmentation.
Provided by the FAC in take off and landing phases from 3s after take off to 1300ft and 1300ft to 50ft RA and at least Conf 1 selected. Lasts minimum of 15 secs.

Question 4

FAC functions

Answer 4

Yaw function - yaw damping, rudder trim and limitation
Flight envelope function - speed scale management, min/max speed computation, maneuvering speeds, Alpha floor protection
Low energy alert function
Windshear detection function

Question 5

What is he difference between climb and open climb?

Answer 5

Both control the pitch to manage the speed target with max climb thrust engaged. Open climb will ignore altitude constraints whereas climb will meet them.

Question 6

When can NAV be used in the terminal area?

Answer 6

NAV mode may be used in the terminal area, provided:
GPS PRIMARY is available, or
HIGH accuracy is displayed, and the appropriate RNP is checked or entered on the MCDU, or
FMS navigation is cross-checked with navaid raw data.
