Answer 9

You are in Direct Law

Question 10

What are the pitch and roll angle limits indicated by the green = signs?

Answer 10

• Pitch: +30° up/-15° down

* Roll: +/- 67°

Question 11

How can you determine you are in Alternate Law?

Answer 11

• Amber x’s at the pitch (30° UP/15° DN) and bank (67°) limits
• Only Vls and Vsw is displayed on the airspeed scale

Question 12

When would the sideslip index change from yellow to blue?

Answer 12

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

Question 13

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

Answer 13

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

Question 14

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

Answer 14

• Magenta – Managed speed computed by the FMGC

* Blue – Selected speed on the FCU

Question 15

What is VLS and how is it displayed?

Answer 15

• 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 16

What speed does VMAX represent and how is it displayed?

Answer 16

• 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 17

What is Green Dot speed?

Answer 17

• 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 18

What is Ground Speed Mini?

Answer 18

• Based on a calculated groundspeed at the runway

* Protects against actual groundspeed dropping below this calculated groundspeed

Question 19

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

Answer 19

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

Question 20

Is this protection available in selected speed?

Answer 20

No – Managed speed only

Question 21

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

Answer 21

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

Question 22

When is altitude alerting automatically inhibited in flight?

Answer 22

• When slats are extended with the landing gear down

* On approach after glide slope capture

Question 23

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

Answer 23

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

Question 24

When is Radio Height displayed on the PFD?

Answer 24

Below 2,500 feet

Question 25

Information from ILS receiver 1 is displayed where?

Answer 25

* Captain’s PFD | * F/O’s ND

Question 26

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

Answer 26

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