PC Briefing Questions Flashcards
(31 cards)
What level of Autopilot redundancy is provided with LAND 3 annunciated?
FAIL OPERATIONAL. A single fault cannot prevent the Autopilot system from making an automatic landing.
What level of Autopilot redundancy is provided with LAND 2 annunciated?
FAIL PASSIVE. A single fault cannot cause a significant deviation from the flight path.
During an asymmetric go-around from LAND 2 or LAND 3 approach, will automatic engagement of LNAV cause the autopilot relinquish control of the rudder?
Yes, at the first change of a lateral or vertical mode, whether manually or automatically selected, I.e. LNAV, TRK SEL or ALT capture.
With AUTOTHROTTLE L unserviceable is it possible to do a CATlllB approach?
NO. Both autothrottles must be serviceable.
With one TO/GA switch inoperative, can you conduct a CATlllA approach?
YES. Downgrade autoland to “LAND 2” capability.
The autoland system is not fail-operational. The NO LAND 3 advisory message may be displayed.
With both TO/GA switches inoperative, can you conduct an LVO approach?
NO.
Autopilot and flight director are not to be used below 500ft AGL or MDA, whichever is higher.
With one Flight Director System unserviceable is it possible to do a CATlllB Approach?
NO.
Downgrade to LAND 2.
What is the Alert Height of the B777?
200ft RA
If the F/O’s Autopilot disconnect switch is inoperative, can you conduct a CAT ll approach?
NO.
One may be inoperative provided:
a) . Autopilot is not used below 1,500ft AGL
b) . Approach minimums do not require the use of Autopilot
What is the significance of the PFD Localizer or Glideslope deviation indicator turning Amber or flashing?
Excessive deviation from the required flight path at low RA
What pilot action is required in the event of flashing LOC or GP deviation during approach ABOVE alert height?
If the aircraft is correcting, the approach may be continued.
What pilot action is required in the event of flashing LOC or GP deviation during approach BELOW alert height?
A go-around must be commenced or, if visual conditions permit, the autopilot may be disconnected and a manual landing made.
What is the significance of a Master caution light and aural signal below alert height?
Below alert height all unrelated Caution Alerts are inhibited. A master caution light and/or aural signal below alert height requires a go-around, or a manual landing if visibility permits.
Note: The EICAS messages will still appear, only the master caution and beeper are inhibited.
What AFDS category is available during an engine inoperative approach with LAND 3 in the AFDS?
CATlllB
If correct FMA mode changes do not occur the F/O will call?
“NO FLARE”
“RETARD”
“NO ROLLOUT”
What indication would you expect during Short Term Interference (ie vehicle or preceding aircraft)?
Erratic ILS Raw Data indications. A/P disregards ILS signal and continues in altitude stabilised mode based on ADIRU data.
What indication would you expect during Long Term Interference or Failure?
A/P remains in attitude stabilised mode.
Crew indications invalid mode(s)；
Amber line through affected mode(s)
EICAS Caution message
Master Caution lights and beeper
Flight Director command bar(s) disappear
What are the maximum wind components for non contaminated landing in LVP?
Headwind 25 kts
Tailwind 15 kts
Crosswind 25 kts
What are the maximum crosswind components for landing on a contaminated runway?
Standing water/Slush/Loose snow
20 kts
Ice/Compacted Snow
15 kts
Which EICAS messages can affect LVO capability without causing a change on the AFDS status annunciation or a note in the checklist?
SINGLE SOURCE DISPLAYS (LVO not permitted)
AUTOTHROTTLE (CATlllB not permitted)
What is the minimum autopilot disconnect height on an ILS approach if LAND 3 or LAND 2 is not annunciated?
200ft AGL
For takeoff in low visibility conditions when is a take off alternate required?
Whenever the departure airport conditions are below the published ILS landing minima or for the approach in use.
The destination alternate has CATlllB capability, is it permissible to file this airport as an alternate if the weather is below CAT1?
No.
At the planning stage you cannot use LVO minima as a basis for calculating minima for filing as an alternate.
After dispatch the destination weather forecast indicates LVP will be required. Your alternate also indicates LVP will be required, is this allowed?
Your destination alternate should permit CAT 1
