Q

Where does the performance computer obtain inputs to calculate the correct VREF speed?

A

SAT and pressure altitude (ADM), aircraft weight (MCDU), and flap handle

20
Q

The heading sources for each EBDI are:
HDG1 ______
HDG2______
STBY______

A
#1 IRS
#2 IRS
Magnetometer
21
Q

If all 4 displays fail on approach, what is the primary backup?

A

HUD

22
Q

Which Audio Control Panel(s) is/are active during E-BATT ONLY operations?

A

Pilot’s and co-pilot’s audio control panels, using the emergency selection for COMM 1. Co-pilot’s panel will not illuminate but is operative.

23
Q

What will happen if the pilot’s primary flight display goes blank?

A

DU2 will go to PFD

24
Q

In the event of a dual generator failure, which MCDU will automatically standby engine instruments and can be powered down to E-BATTS?

A

MCDU 1

25
Q

In the event of a dual generator failure, which MCDU will automatically display back up radio tuning and can be powered down to E-BATTS?

A

MCDU 3

26
Q

Under the TEST menu key, how is the radar altitude checked?

A

Three steps

  1. 100 ft will be displayed on the ADI portion of both PFDs
  2. An amber line 100’ below the lubber line on both altimeters
  3. Ground awareness symbology appears.
27
Q

While established in an FMS holding patter, if the exit prompt is pressed, what will the FMS direct the aircraft to do?

A

Proceed directed to the holding fix, fly over the holding fix, then proceed on course.

28
Q

On an FMS-coupled approach, when does the APPROACH light illuminate?

A

2NM prior the FAF/FAWP

29
Q

If VNAV is engaged, when does the VNAV track change alert occur?

A

Approx 1 minute prior to the top of descent point

30
Q

The altitude display tape on the PFDs will display dashes on the last two digits when….

A

The rate of climb or descent exceeds 1000 fpm

31
Q

VOR and ILS course data displayed on the PFD in what color?

A

Green

32
Q

FMS Course data is displayed on the PFD in what color?

A

Blue

33
Q

While being vectored for an ILS approach, if the glide slope is intercepted before the localizer, and approach is selected, what will be the effect?

A

The glide slope will not be intercepted

34
Q

How should a back course approach be set?

A

The inbound course is set, MDA set in display controller and GP; when cleared for the approach, select BC on the guidance panel

35
Q

How should a RNAV (GPS) approach be set up to fly the approach to the DA?

A

Just like an ILS. Set DA in the display controller. Arm APP when prompted. Set missed app alt in ALT preselector

36
Q

To fly the final segment of an RNAV (GPS) approach flown in BLUE DATA, is an approach annunciation required? Are there exceptions?

A

Yes, except for NDB or VOR based approaches flown in blue data if the NAVAID is being displayed as well.

37
Q

Why won’t the FMS accept a HOLD directly over a waypoint?

A

The HOLD must be selected 1 minute prior to the holding to perform the math required for proper entry and speed.

38
Q

Will the autopilot disconnect when selecting the Go-Around Mode?

A

No

39
Q

How can the flashing of an amber message and its associated chime be canceled?

A

By pressing either the red “W” or the amber “C”
