Navigation Flashcards
The FMGS tunes the navigation radios to determine the aircrafts:
Present position.
Manual tuning of the VOR and ILS radios is available by crew entry to the:
MCDU’s (multi purpose control and display units).
A backup tuning method of VOR and ILS is available on the:
RMP’s (Radio Management Panel).
If ADIRU 2 fails, the ATT HDG selector is selected to FO3 so that ADIRU 3 will be supplied with MMR —— data.
MMR (multi mode receiver) 2 data.
If one GPS receiver fails, the 3 ADIRU:
Automatically select the only operative GPS receiver.
The GPS acquisition mode continues until the MMR is able to track at least:
4 satellites.
The Nav GPS mode operates as long as —- satellite signals remain available.
4 satellites.
ILS 1 is controlled by MMR (multi mode receiver):
1

The NAV ROSE or ARC position.
The DME frequency is ————— selected for the VOR or ILS.
Automatically selected and automatically displayed when available.
The DME receiver can tune —— stations for navigational purposes but only the auto tuned or manually tuned DME is displayed.
Five DME stations.
The ILS information on the PFD is provided by the ————- ILS Radio.
Respective.
If one FMGC fails the remaining FMGC controls the navaid receivers:
On both sides.
A dim underlined M will appear after the identifier on the FMGC, indicating the navaid has been:
Manually tuned.
The predictive windshear system operates below:
2300ft AGL
No PWS (predictive windshear) advisories are provided to the crew above:
1500ft AGL or below 50ft AGL.
The PWS scans the airspace within a range of:
5nm in front of the aircraft.
