Autoflight

Question 1

What is the FPA?

Answer 1

Flight Path Angle is a pilot-selectable pitch attitude (in degrees) of climb or descent

FGCS adjusts thrust and pitch to maintain path angle and airspeed

Question 2

What does the TOGA button do?

Answer 2

On ground……activates takeoff guidance crossbars

In flight…..activates Go-Around guidance

Question 3

What do the takeoff guidance crossbars do?

Answer 3

Maintain extended runway centerline

Maintain pitch guidance according to slat/flap setting

Question 4

When is the TOGA mode deactivated?

Answer 4

Another vertical mode selected
Autopilot is activated
TCS button is pressed

Question 5

When will the FD automatically display?

Answer 5

TOGA button is pressed
Autopilot is activated
Windshear detection

Question 6

What is the function of the TCS button?

Answer 6

Allows manual override of the autopilot
When released, airplane maintains new altitude (provided ALT was the active vertical mode) but will return to previous lateral mode (except ILS, autopilot will recapture the LOC/GS)

Question 7

What will disengage the autopilot?

Answer 7

AP button on the GP is pushed
Any manual pitch trim is activated
Either AP/TRIM DISC button is pushed
Stick shaker activated
Flight controls in direct mode
Aileron or elevator controls disconnected
Overpowering the yoke
Internal system failures

Question 8

When will the FGCS automatically select half-bank? What is the bank angle?

Answer 8

FL250

17° bank angle

Question 9

Can the yaw damp be deactivated if the autopilot is on?

Answer 9

Yes, it is independent of the autopilot

Question 10

When will the auto-throttles engage on the ground? In flight?

Answer 10

On ground…..AT TO (GP) is armed and the TL are greater than 50°

In flight…..AT (GP) is armed and airplane is greater than 400 ft AGL

Question 11

Will the auto-throttles compensate for gusty wind conditional?

Answer 11

Yes, up to 5 kts

Question 12

What will disengage the auto-throttles?

Answer 12

AT (TL or GP) is pushed
TLA difference greater than 8°
TL at idle with weight-on-wheels or wheels spinning
Internal system failures

Question 13

What is SPDe? What mode uses SPDe?

Answer 13

Speed on elevator, thrust is fixed and pitch is adjusted to maintain airspeed (VS changes)

FLCH uses SPDe for climbs and descents

Question 14

What is SPDt? What modes use SPDt?

Answer 14

Speed on thrust, thrust is adjusted to maintain selected airspeed
FPA, VS, GS, ALT, ASEL

Question 15

What are the AT modes?

Answer 15

SPDe, SPDt, TO, GA, HOLD, RETARD (@30 ft RA)

Question 16

What does LIM and OVRD mean on the FMA?

Answer 16

LIM…..The selected vertical mode requires more or less engine thrust than is available

OVRD…..The TL are being manually moved (no AP disengagement)

Question 17

When is CRZ automatically selected?

Answer 17

When +100 ft of selected altitude for 90 seconds

Desired airspeed must be achieved or it will remain in CLB mode

Question 18

What does the SRC button do?

Answer 18

Selects pilot or co-pilot as the data source for the AFCS?

Question 19

What does the red AP/TRIM DISC button on the yoke do?

Answer 19

Disconnects the autopilot

Stops all trim actuation if button is pushed and held

Question 20

What does the PREV button do?

Answer 20

Allows the capture of ILS/BC course while still using the FMS as the basic NAV source provided the AUTO TUNE function is enabled on the MCDU and the approach is loaded in the FMS.
