Question 16

What is the alert height of the 777?

Answer 16

200’ RA

Question 17

What level of redundancy is provided with LAND 3 annunciated?

Answer 17

Fail Operational

A single fault cannot prevent the autopilot system from making an automatic landing

Question 18

What level of redundancy is provided with LAND 2 annunciated?

Answer 18

Fail Passive

A single fault cannot cause significant deviation from flight path

Question 19

Following a go around from an engine inoperative CAT 3B ILS with TAC inop at which point will the autopilot relinquish control of the rudder?

Answer 19

At the first change of a lateral or vertical mode, whether manually or automatically selected

Question 20

What is the significance of the PFD localizer or glideslope deviation indicator turning amber and flashing?

Answer 20

Excessive deviation from the required flight path at low RA

Question 21

What pilot action is required in the event of flashing LOC or GP deviation during aproach:
Above Alert Height?
Below Alert Height?

Answer 21

Above: If the aircraft is correcting, the approach may be continued
Below: A go around must be commenced unless visual conditions exist and a manual landing can be made

Question 22

What is the significance of a Master Caution light and Aural signal below Alert Height?

Answer 22

Below alert height, all unrelated cautions are inhibited. Master caution and/or aural signal requires a go around, unless visual conditions exist and a manual landing can be made

Question 23

Short term ILS interference will result in what?

Answer 23

A/P disregards ILS signal, continues in attitude stablised mode based on ADIRU data
Might get erratic ILS raw data indications

Question 24

Long term ILS interference will result in what?

Answer 24

A/P remains in attitude stabilised mode
Amber line through affected modes
EICAS caution message 
Master caution and bleeper
FD command bars disappear

Question 25

Approach ban?

Answer 25

If above 1000’: When RVR reduces to below minimum, can descend to 1000ft AAL, if not above minimum, commence go around

If below 1000’: When RVR reduces to below minimum, if visual reference not established by minima, commence go around

Question 26

What is the procedure for briefing reversion minima if the weather improves?

Answer 26

Do not reset the radio minimums selector
Brief the revised reversion capability
If above 1000’: continue approach to best capability of approach as briefed
If below 1000’: continue to minima
