Navigation

Question 1

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

Answer 1

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

Question 2

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:

Answer 2

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

Question 3

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

Answer 3

all pitot and static probes.

Question 4

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

Answer 4

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

Question 5

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

Answer 5

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

Question 6

In normal operation, GPS receiver 1 supplies

Answer 6

ADIRU1 and ADIRU3, the GPS receiver 2 supplies ADIRU 2

Question 7

RMP 3 located on the overhead panel is

Answer 7

Not used for NAVAIDS tuning

Question 8

ILS 1 information is displayed on

Answer 8

PFD 1 and ND2

Question 9

Aircraft has 2 DME. The frequency set automatically on

Answer 9

The DME corresponds to that set on the VOR or ILS

Question 10

Pressing the NAV key engages

Answer 10

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

Question 11

The attitude sphere of the PFD displays the

Answer 11

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

Question 12

If time between two consecutive predetermined callouts exceeds

Answer 12

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

Question 13

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

Answer 13

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

Question 14

The loudspeaker announces RETARD at

Answer 14

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

Question 15

If time between two consecutive predetermined callouts exceeds

Answer 15

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

Question 16

The aircraft has two ATC transponders which are controlled by

Answer 16

A dual control box on the center pedestal

Question 17

TCAS STBY appears in green when

Answer 17

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

Question 18

ATCs or both RAs fail; the crew turns OFF

Answer 18

the ALT RPTH switch

Question 19

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

Answer 19

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

Question 20

At landing the predictive windshear warning alerts are inhibited below

Answer 20

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

Question 21

The predictive windshear system aural alerts have priority over

Answer 21

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

Question 22

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

Answer 22

10ft and 2,450ft

Question 23

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

Answer 23

30ft and 2,450ft RA

Question 24

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

Answer 24

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

Question 25

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

Answer 25

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

Question 26

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

Answer 26

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

Question 27

TCAS detection capability is limited to intruders flying within

Answer 27

A max range of 100 NM

Question 28

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

Answer 28

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

Question 29

PFDs difference at ground check + - 25ft

Answer 29

Std by alt + - 300ft HDG NDs = 4º
