Instruments/Navigation/Communication
1. If a TERR pb FAULT light illuminated, would that affect the basic GPWS modes?
This amber light illuminates, along with an ECAM caution, if the terrain detection function fails. The terrain is not
shown on the ND. The basic EGPWS modes 1 to 5 are still operative.
2. With the RDCR GND CTL pushbutton in AUTO when does the CVR and Digital Flight Data Recorder
(DFDR) energize?
At the first engine start.
3. If ACP #1 (Captain's) should fail, how would the pilot restore communications?
Select CAPT 3 on the Audio Switching panel. The captain uses his acoustic equipment and the third occupant’s ACP.
4. Is the radar display available in all modes of the ND selector on the EFIS Control Panel?
Any ND mode except PLAN.
5. Does the EGPWS use radar signals to "ground map" terrain?
The enhanced function is based on a worldwide terrain database. It provides Terrain Awareness Display (TAD)
which predicts terrain conflict and displays the terrain on the ND, and Terrain Clearance Floor which triggers a
warning. The TAD function computes a caution and warning envelope ahead of the aircraft and when the
boundaries of this envelope conflict with the database terrain information, it generates alerts.
6. Why is it very important to maintain a 'lights out' condition on the ECAM control panel during flight?
To ensure any current cautions or warnings are displayed immediately on the ECAM.
7. If the upper ECAM screen fails, will the crew still be able to see E/WD data?
E/WD has priority over the SD. If the upper ECAM screen fails (or is selected off), E/WD data is automatically
transferred to the lower screen.
8. If all systems were working normally, and a crewmember wanted to remotely tune a VOR through
the RMP, would that have any effect on the FMGC NAV functions?
The RMP NAV key engages the radio navigation backup mode. It takes control of the VOR, ILS, (MLS, and ADF not
installed) receivers away from the FMGC and gives it to the RMP.
9. How do we know the ILS has been properly tuned and identified?
ILS identification is decoded by the ILS receiver, and displayed in magenta on the lower left of the ND.
10. What does the amber "=" sign mean on the airspeed tape?
This symbol shows the VFE corresponding to the next flap lever position.
11. Where is the information normally displayed by DMC #1? DMC #2?
DMC 1: PFD 1, ND 1, upper ECAM DU
DMC 2: PFD 2, ND 2, lower ECAM DU
DMC 3: Spare which can replace DMC 1 or DMC 2

12. Which RMP is functional in the emergency electrical configuration?
Only RMP 1 is operational in EMER ELEC CONFIG.
13. What would a steady FAULT light in the #1 IR indicate?
Non-Enhanced:
FAULT
Steady: The respective IR is lost.
Flashing: Attitude and heading information may be recovered in ATT mode.
ALIGN
Steady: Respective IR is operating normally in align mode.
Flashing
Enhanced:
IR pb:
OFF: Inertial data output disconnected.
FAULT Light: Illuminates amber ECAM caution triggered when a fault affects the respective IR.
Steady: The respective IR is lost.
Flashing: Attitude/heading information may be recovered in ATT mode.
IR 1 (2) (3) Mode Rotary Selector
OFF: The MSU is not energized. ADR and IR data are not available.
NAV: Normal mode of operation Supplies full inertial data to aircraft systems.
ATT: IR mode supplying only attitude and heading information when the system loses its ability to
navigate. The heading must be entered through the MCDU and must be reset frequently (approximately
every 10 minutes).
14. What would a flashing IR FAULT light indicate?
Non-enhanced: Attitude and heading information may be recovered in ATT mode.
Enhanced: Illuminates amber ECAM caution triggered when a fault affects the respective IR.
15. What is green dot speed?
Engine-out operating speed in clean configuration. This green dot appears when the aircraft is flying in the clean
configuration, showing the speed corresponding to the best lift-to-drag ratio.
16. The Inertial Reference (IR) provides what information to the PFD?
Attitude
Heading
Track
Flight Path Vector
