• Only VLS and VSW is displayed on the airspeed scale

Question 11

When would the sideslip index change from yellow to blue?

Answer 11

In case of an engine failure during takeoff/go-around, it is now a blue beta target.

Question 12

What does the yellow speed trend line on the airspeed display indicate?

Answer 12

The speed the aircraft will reach in 10 seconds if acceleration/deceleration remains constant.

Question 13

What is the difference between the magenta and blue target airspeeds?

Answer 13

• Magenta – Managed speed computed by the FMGC

* Blue – Selected speed on the FCU

Question 14

What is VLS and how is it displayed?

Answer 14

• Represents lowest selectable speed providing an appropriate margin to the stall speed
• Defined by the top of the amber strip along the airspeed scale
• In approach mode is equivalent to VREF

Question 15

What speed does VMAX represent and how is it displayed?

Answer 15

• It is the lowest of VMO/MMO, VLE, or VFE

* Defined by the bottom of a red and black strip along the speed scale

Question 16

What is Green Dot speed?

Answer 16

• Engine out operating speed in clean configuration
• Appears when the aircraft is in the clean configuration
• Corresponds to the best lift-to-drag ratio

Question 17

What is Ground Speed Mini?

Answer 17

It’s a computed target speed during the approach that maintains the aircraft energy above a minimum level
ensuring standard aerodynamic margins versus stall, this ground speed mini is:
• Based on a calculated groundspeed at the runway
• It will protect against actual groundspeed dropping below this calculated groundspeed due to wind.

Question 18

What is SRS, When does it appear on the PFD? What speed does it maintain?

Answer 18

Speed reference system, in takeoff and go-around
[It maintains V2+10(2 ENG), V2- (V2+15) 1ENG, or speed that insures at least a vertical path of 120feet/
minute], it also provides pitch attitude protection during takeoff (18° max or 22° max in wind-shear)
!21
LS pb
Displayed in case of loss of L+R elevators.
PITCH by manually applying trim to the THS
LATERAL uses the rudder pedals.
Note: During takeoff the flight crew inadvertently sets an ALT on the FCU below the current altitude, the aircraft will remain in SRS mode until the flight crew takes some other action

Question 19

What are the SRS engagement conditions?

Answer 19

In ground for take off:
• thrust levers set to TOGA or FELX
• V2 set in the PERF page MCDU
• The slats extended
• A/C on ground for at least 30 seconds

Go-around:
• Flap lever is at least in position 1, and
• The A/C is in flight, or
• The A/C is on the ground for less than 30 seconds (rejected landing), AP disengages and can be reengaged
5 sec after lift off

Question 20

What are the disengagement conditions?

Answer 20

• Automatically at acceleration ALT(ACC ALT)(ALT)(ALT CST) above 400 feet
• If crew engages another vertical mode
• If crew selects a speed (clickclickclick ) is heard

Question 21

What are the 2 sub-modes of the runway mode (RWY) and what do they provide?

Answer 21

• RWY mode: lateral guidance during TO roll up to 30 feet RA if LOC signal is available
• RWY TRK mode: gives lateral guidance to same track during the engagement (at 30 feet)
Note: RWY TRK mode engages automatically at 30 ft (RA) if NAV mode does not engage (NAV not armed prior to takeoff).

Question 22

What are the (RWY) engagement conditions?

Answer 22

• thrust levers set to TOGA or FELX
• V2 set in the PERF page MCDU
• The slats extended
• A/C on ground for at least 30 seconds
• A/C receiving a LOC signal and LOC deviation is less than ½ dot
• A/C heading is within 20° of the ILS course
• The ILS course is identical to the runway heading.

Question 23

How can you disengage the LAND mode?

Answer 23

• When in go-around

* When both AP/FDs are disengaged

Question 24

Which of the speeds displayed on the PFD are an actual flap/slat position and which ones are flaps
lever position?

Answer 24

VLS, over speed warning are based on the actual flap/slat position (Outers)

VFE, VFE NEXT based on the flap lever position (Inners)

Question 25

What does it mean when you see the magenta target airspeed triangle above VAPP on approach?

Answer 25

Ground Speed Mini has increased speed due to a higher headwind component at your present location than
what was calculated at the runway.

Question 26

Is this protection available in selected speed?

Answer 26

No – Managed speed only

Question 27

What would be indicated if the altitude window changed from yellow to amber?

Answer 27

The aircraft has deviated from the FCU selected altitude or flight level.

Question 28

When is altitude alerting automatically inhibited in flight?

Answer 28

• When slats are extended with the landing gear down

* On approach after glide slope capture

Question 29

What does it mean when the altitude digits change from green to amber?

Answer 29

The aircraft has descended below the MDA/DH entered into the FMGC.

Question 30

When is Radio Height displayed on the PFD?

Answer 30

Below 2,500ft

Question 31

What is Soft Altitude (Cruise) mode?

Answer 31

Soft ALT mode corrects minor deviations from the Mach target by allowing a +/- 50ft variation from the CRZ FL. It imporves fuel efficiency, pax comfort, minimizes thrust variations.

Question 32

Information from ILS receiver 1 is displayed where?

Answer 32

• Captain’s PFD

* F/O’s ND

Question 33

What would a flashing amber ILS indicate on the bottom of the PFD?

Answer 33

Flashes amber when APPR mode is armed and the ILS display is not selected.
