What is signified by the IAS target being magenta or blue?

Magenta = managed speed mode
Blue = FCU selected speed mode

2

What is shown on the bottom left corner of the PFD? And when?

Mach number when greater than M.5 in green.
At slow speed, ILS info is displayed when selected.

3

In a managed descent, how is the Max ECON Speed Range represented?

In a managed descent, how is the Min ECON Speed Range represented?

Maximum:
The lowest of....
+20 kt
VMAX/VMO -3 knots
MMO -0.006.
or +5kt if a speed constraint applies.

Minimum:
The highest of....
-20 kt
Green dot, F, S or VLS.

4

How is the Speed Target Displayed if it is NOT in the Window? i.e. off scale.

Value is displayed as numbers below or above the speed scale

5

What would cause NEG to appear on Altitude strip?

1. Aircraft below mean sea level
2. Incorrect QNH setting

6

What is signified by F, S, and Green Dot speed?

F (minimum flap retraction speed), S (minimum slats retraction speed) and Green Dot (best lift/drag ratio speed).

7

If, on the PFD, the Altitude Bug is 5000’ (blue), where else will 5000’ be displayed?

FCU

8

How does the Target Altitude indication change if the Baro Set Knob on the EFIS Control Panel, is pushed / pulled?

Pushed for QNH (Alt.)
Pulled for STD (F.L.)

How is the Actual Track of the A/C represented?

Small green diamond on both PFD & ND.

10

What information is given by the F.P.V?

FPA in the vertical plane.
Track/Drift in the lateral plane.

11

What is always directly below the F.P.V?

Track diamond.

12

How is the ILS course represented?

Dagger-shaped symbol in magenta + course pointer.

13

The Wind Arrow / Digits indicate what?

Wind direction both in degrees True, arrow only appears > 2 knots.

14

What does M or R mean (next to a VOR or ADF indication)?

M = tuned manually by the pilot via MCDU.
R = from RMP.

15

What provides the ND with the Groundspeed and TAS info?

ADIRS

16

Where can VOR Beam (bearing pointer, CDI) Bars be displayed? Can you lock onto a VOR Radial?

Rose VOR, ND. Cannot lock on.

17

How is the PLAN Mode Orientated?

True North.

18

What does the speed trend arrow tell you?

It shows the speed the aircraft will reach in 10 seconds.
