Aircraft Systems Knowldge (Automatic Flight)

Question 1

On takeoff, what speed does SRS command with both engines operating?

(FMA)

Answer 1

SRS gives pitch guidance to maintain V2 + 10

Question 2

On takeoff, what speed does SRS command if an engine failure is detected?

(FMA)

Answer 2

SRS gives pitch guidance to maintain the greater of V2 or current speed, Limited to V2 +15

Question 3

When does the airplane exit SRS mode?

(FMA)

Answer 3

Automatically at the Acceleration Altitude or when another Vertical Mode is engaged

Question 4

With V/S active, waht would happen is you select a higher speed?

(PFD/FMA)

Answer 4

Thrust would be commanded to increase (up to CLB) until the selected speed os attained. Then thrust would reduce to maintain selected speed.

Question 5

During a normal Takeoff, when will the A/THR become engaged?

Answer 5

When the thrust levers are moved to the CLB detent.

Question 6

In a Managed Climb, what FMA changes will occur if you pull HDG?

(FMA/FCP)

Answer 6

NAV mode will change to HDG, and CLB mode will change to OP CLB.

Question 7

In Managed Descent, what FMA changes(s) will occur if you pull HDG?

(3 things)

(FMA/FCP)

Answer 7

NAV will change to HDG

DES mode will change to V/S

THR mode will change to SPEED

Question 8

During an ILS APP, at approx. what altitude will the LOC/GS indication change to LAND on the FMA and LAND what does it mean?

(2 things)

(FMA)

Answer 8

Below 400 RA

LAND indicates that the LOC and GS Modes are locked. No action on the FCU will disengage the LAND Modes, FLARE and ROLLOUT Modes will successively engage.

Question 9

During an autoland, when do you expect the FMA FLARE indication to appear?

(FMA)

Answer 9

40’ RA

Question 10

During an autoland, with the FMA FLARE indication displayed, what actions are occurring within the autopilot and autothrust?

(2 things)

Answer 10

Autopilot aligns yaw axis with runway centerline and flares in pitch

Autothrust reduces to idle if engaged

Question 11

During an autoland, what does ROLL OUT indicate?

(FMA)

Answer 11

The Autopilot is guiding the aircraft along the runway centerline and the yaw bar is displayed on the PFD

Question 12

What are the threee ways you can disconnect the Autothrust?

(3 things)

Answer 12

Push either AUTOTHRUST Instinctive Disconnect pb

Move both Thrust Levers to idle

Push A/THR pb on FCU (will cause THR lock)

Question 13

In level flight with the thrust levers in the CL detent, what will happen to the thrust if you press the instinctive disconnect pb’s?

Answer 13

Thrust will go to CL (matching actual current TL position)

Question 14

What does THR LK mean?

(FMA)

Answer 14

Thrust is fixed at the current setting (could be a fault or pressing the FCU A/THR button)

(Fix by moving thrust levers)

Question 15

How would you get out of THR LK?

Answer 15

Move the Thrust Levers.

Question 16

What triggers A.FLOOR protection to engage?

(2 things)

(FMA)

Answer 16

A. FLOOR is triggered by a predetermined AOA

A.FLOOR means A/THR will command TOGA thrust regardless of T/L position.

Question 17

When the A. FLOOR mode triggers, what does A/THR command?

(FMA)

Answer 17

A/THR will command TOGA

Question 18

What dies TOGA LK indicate?

(FMA)

Answer 18

TOGA LK means TOGA thrust is still being commanded (A.FLOOR triggering conditions are no longer met)

Question 19

How do you get out of TOGA LK?

Answer 19

The A/THR must be disconnected

Question 20

During a Go-Around, what FMA indications will confirm that the Aircraft has entered the GA Phase?

(2 things)

Answer 20

MAN TOGA

SRS

(confirms that aircraft is in the GA phase)

Question 21

The aircraft is in Normal Law and Autothrust is selected OFF. Is A. FLOOR available?

Answer 21

Yes

Question 22

When the aircraft leaves A. FLOOR what FMA change will occur.

Answer 22

A. FLOOR will change to TOGA LK
