Nothing
Which DUs are available during HMG operation?
1 and 4
How is the radar entered in the standby mode?
By selecting standby, or forcing standby via the WOW system.
How can the crew turn on the WX radar on the ground?
Press the STAB button 4 times within 3 seconds
Both pilots select the EMG button on the Audio Control Panel. Over which radio(s) will they transmit and receive?
Pilot and Copilot VHF #1, or VHF #3, depending on A/C serial number
What is indicated if both pilots had ADC 1 displayed in AMBER on the PFD?

DU Failure
What is the minimum recommended temperature in the cockpit, cabin and EER prior to cockpit systems powerup?
+65° F / +18° C
What are the correct indications when testing the EGPWS?
“TERRAIN TEST” display on the INAV, followed by a change of the range ring to five miles, followed by a rebuild of the terrain display.
Where does the performance computer obtain inputs to calculate the correct VREF speed?
SAT and pressure altitude (ADM), aircraft weight (MCDU), and flap handle

If all 4 displays fail on approach, what is the primary backup?
HUD
Which Audio Control Panel(s) is/are active during E-BATT ONLY operations?
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.

MCDU 1
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?
MCDU 3
Under the TEST menu key, how is the radar altitude checked?
Three steps
- 100 ft will be displayed on the ADI portion of both PFDs
- An amber line 100’ below the lubber line on both altimeters
- Ground awareness symbology appears.
While established in an FMS holding patter, if the exit prompt is pressed, what will the FMS direct the aircraft to do?
Proceed directed to the holding fix, fly over the holding fix, then proceed on course.
On an FMS-coupled approach, when does the APPROACH light illuminate?
2NM prior the FAF/FAWP
If VNAV is engaged, when does the VNAV track change alert occur?
Approx 1 minute prior to the top of descent point
The altitude display tape on the PFDs will display dashes on the last two digits when….
The rate of climb or descent exceeds 1000 fpm
VOR and ILS course data displayed on the PFD in what color?
Green
FMS Course data is displayed on the PFD in what color?
Blue
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?
The glide slope will not be intercepted
How should a back course approach be set?
The inbound course is set, MDA set in display controller and GP; when cleared for the approach, select BC on the guidance panel
How should a RNAV (GPS) approach be set up to fly the approach to the DA?
Just like an ILS. Set DA in the display controller. Arm APP when prompted. Set missed app alt in ALT preselector
To fly the final segment of an RNAV (GPS) approach flown in BLUE DATA, is an approach annunciation required? Are there exceptions?
Yes, except for NDB or VOR based approaches flown in blue data if the NAVAID is being displayed as well.
Why won’t the FMS accept a HOLD directly over a waypoint?
The HOLD must be selected 1 minute prior to the holding to perform the math required for proper entry and speed.
Will the autopilot disconnect when selecting the Go-Around Mode?
No
How can the flashing of an amber message and its associated chime be canceled?
By pressing either the red “W” or the amber “C”
What message tones are inhibited when the WARN INHIBIT switch is selected?
Most amber and all blue messages
With WARN INHIBIT selected, are the messages inhibited?
No, on the tones
