1

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.
Slow speed ILS when selected.

3

In a managed descent, how is the ECON Speed Range represented: Above / Below a speed restriction?

ECON SPD +5 knots when constraints applies, otherwise, +20 knots limited to VMAX, VMO -3 knots or MMO -0.06.
ECON SPD -20 knots, limited to 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?

Negative values

6

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

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

10

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

Lateral track + vertical trajectory of the aircraft respect to the ground.

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?
