1
Q

On the pedestal mounted switching panel, the ATT HDG and AIR DATA selectors in NORM mean:

A

ADIRU 1 supplies data to PFD 1, ND1 and ATC 1; ADIRU 2 supplies data to PFD 2, ND2, and ATC 2

2
Q

Normally the IR 1 (2 and / or 3) mode rotary selector is in the NAV position supplying full inertial data to aircraft systems. With the switch in the ATT position:

A

IR part supplies heading and attitude information if the system loses its ability to navigate. Heading must be entered through the MCDU, and reset frequently

3
Q

Air Data Modules ADMs convert pneumatic data for use by the ADIRUs from

A

all pitot and static probes.

4
Q

The MMR enters the ACQ mode after power up or during long periods of lost satellite signal. It remains in this mode until

A

It is able to track at least four satellites, then transfers into NAV mode. To enter in navigation mode more quickly, the MMR uses position, time and altitude from IRS

5
Q

If the number of satellites available drops to three, the altitude bias is frozen and the MMR

A

Enters ALTAID mode using the IR altitude corrected with the altitude bias

6
Q

In normal operation, GPS receiver 1 supplies

A

ADIRU1 and ADIRU3, the GPS receiver 2 supplies ADIRU 2

7
Q

RMP 3 located on the overhead panel is

A

Not used for NAVAIDS tuning

8
Q

ILS 1 information is displayed on

A

PFD 1 and ND2

9
Q

Aircraft has 2 DME. The frequency set automatically on

A

The DME corresponds to that set on the VOR or ILS

10
Q

Pressing the NAV key engages

A

The radio navigation backup mode; it takes control of the VOR, ILS, MSL, and ADF receivers. The receivers are now controlled by the RMP and no longer by FMGC

11
Q

The attitude sphere of the PFD displays the

A

RA height in digital format, when the aircraft is below 2,500 ft . RA indication changes for every 10 ft down to 50ft, then 5ft down to 10ft, and then every foot

12
Q

If time between two consecutive predetermined callouts exceeds

A

11 seconds above 50 ft or 4 seconds below 50ft, the present height is repeated at regular intervals of 4 seconds

13
Q

Normally the CAPT PFD displays the RA1 height and the F/O

A

PFD displays the RA2 height. If either RA fails, both PFDs display the height form the remaining one

14
Q

The loudspeaker announces RETARD at

A

20ft, or at 10ft if autothurst is active and one autopilot is in LAND mode

15
Q

If time between two consecutive predetermined callouts exceeds

A

11 seconds threshold above 50ft, the present height is repeated at every 4 seconds below 50ft

16
Q

The aircraft has two ATC transponders which are controlled by

A

A dual control box on the center pedestal

17
Q

TCAS STBY appears in green when

A

The crew selects TCAS STBY ON ATC/ TCAS panel; both

18
Q

ATCs or both RAs fail; the crew turns OFF

A

the ALT RPTH switch

19
Q

The weather radars have a predictive windshear capability. The Predictive Windshear System PWS operates when the PWS switch is in AUTO position and the aircraft is below

A

2,300ft AGL, and the ATC is switched to the ON or AUTO position, and either engine is running

20
Q

At landing the predictive windshear warning alerts are inhibited below

A

50ft, the visual and aural warning alerts are downgraded to caution alerts between 370ft AGL and 1,5NM

21
Q

The predictive windshear system aural alerts have priority over

A

TCAS, GPWS, and other FWC aural warnings, and are inhibited by WSH detection by FMGC and stall warning aural messages

22
Q

GPWS for modes 2,4,5 between 30ft and 2,450ft and for modes 1 and 3 between

A

10ft and 2,450ft

23
Q

The GPWS generates aural and visual warnings when certain conditions occur between

A

30ft and 2,450ft RA

24
Q

In addition to the basic GPWS functions, the GPWS has an enhanced function (EGPWS) which provides, based on a worldwide terrain database a

A

Terrain Awareness (TAD) which predicts the terrain conflict and displays the terrain on the ND; a Terrain Clearance Floor (TCF), which improves the low terrain warning during landing

25
Q

If the aircraft descends during the initial takeoff climb or during a go-around, GPWS lights come on and the aural alert

A

DON’T SINK sounds repeatedly the lower cutoff limit is 30ft RA

26
Q

TCAS detects any aircraft equipped with transponders flying in its vicinity, display

A

Potential and predicted collision targets, issues vertical orders to avoid conflict

27
Q

TCAS detection capability is limited to intruders flying within

A

A max range of 100 NM

28
Q

TCAS interrogates transponder of intruders form transponder reply, TCAS determines its relative

A

Bearing, its range and closure rate, its relative altitude if available (ATC mode )

29
Q

PFDs difference at ground check + - 25ft

A

Std by alt + - 300ft HDG NDs = 4º
