A

No.

Except maybe Australia

Omey 8.1.3.2.1

32
Q

ATC cancel LVP and revert to Cat one operations during the approach to increase traffic flow. Could this be a threat for your auto land?

A

Possibly
The ILS SENSITIVE AREA MAY NOT BE PROTECTED

AUTOLAND RECOMMENDED BELOW 1500 METERS cloud 300 feet below

Performing an auto land in
CAT 1 conditions, be sure to inform ATC.

A

Fail operational

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

42
Q

What level of auto pilot redundancy is provided with Land2 annunciated?

A

Fail passive

A single fault cannot cause a significant deviation from the flightpath

43
Q

During an asymmetric go round from Land2 or LAND3 approach will automatic engagement of LNAV cause the autopilot relinquish control of the rudder?

A

Yes, at the first change of LATERAL OR VERTICAL MODE, whether manually or automatically
LNAV
TRK SEL
ALT

Be ready with rudder
(Usually auto engagement if LNAV at 200’ Ap, 50’ manually)

44
Q

With One TOGA switch in operative can you conduct a CAT3A approach?

A

Yes.
The system is not fail operational.
Downgrade autoland to Land 2 capability.

No Land 3
advisory message may be displayed

45
Q

With both TOGA switches in operative can you conduct an LVO approach?

A

No

Auto pilot and flight Director are not to be used below 5 00 feet AGL or MDA whichever is higher.

Please find reference!

46
Q

With one flight Director system unserviceable is it possible to do a cat3B approach?

A

No.
With one autopilot flight director system out (2/3 autopilots working),
LAND 2 will show.

See MEL 22-11-01

47
Q

If 2 out of three of the auto pilots are unserviceable, can you do an LVO approach?

A

MEL 22-11-01B

No.

NO AUTOLAND will show.

Only one flight director available.

48
Q

A

No.

MEL 22-11-08

No auto pilot below 1500 feet AGL

Approach minimum do not require use of auto pilot (no LVO)

49
Q

What is the significance of PFD localiser or glide slope deviation turning Amber and flashing?

A

PRACTICAL ONE

EXCESSIVE DEVIATION FROM THE REQUIRED FLIGHTPATH AT LOW RA

ABOVE ALERT HEIGHT:
If the aircraft is correcting approach may be continued

BELOW ALERT HEIGHT:
Go around must be commenced
Or if visual disconnect and Land

50
Q

What is the significance of a master caution light and aural signal below? Alert height?

A

Below alert height all unrelated caution alerts are inhibited.
A master caution light and or aural signal below alert height requires a go round, or manual landing if visibility allows.

Note : EICAS MESSAGES will still appear. ONLY THE MASTER CAUTION AND BEEPER ARE INHIBITED.

Therefore, on Elvio approach always important to take note of 200 feet RA

51
Q

What auto land category is available during engine in operative approach with Land 3 in the AFDS?

A

CAT 3B

52
Q

If correct FMA mode changes do not occur the first officer will call

A

No flare (40’)
Retard (25’)
No rollout (2’-runway)

53
Q

What indication would you expect during short term interference?
(Vehicle or proceeding aircraft)

A

Erratic ILS raw data indications

(Auto pilot disregard ILS signal and continues in attitude stabilised mode based on ADIRU date)

Usually open interference less than 15 seconds (or four seconds blow alert height) = no EICAS messages

54
Q

What indication would you expect during long-term interference or failure of the localiser of glideslope signal?

A

Amberline through affected mode

EICAS caution message (AUTOPILOT)

Master caution, lights and beeper

Flight Director command bar disappear

(Basically if not visual go around, the signal has been disturbed for more than 15 seconds, or four seconds below alert height)

55
Q

What are the maximum wind components for noncontaminated landing in LVP?

A

25 head
25 cross
15 tail

(be sure to respect the contaminated runway effect on Crosswind)
Anything near 20 knot Crosswind should be considered
(Medium to poor makes it 17knots)

Note 2:
Remember to reduce Crosswind limits by 5 kn on wet or contaminated runways whenever asymmetric reverse thrust is used

56
Q

If performing an engine out landing on a runway with a crosswind of 20 kn in heavy rain, is there anything you should consider?

A

Yes, the FCOM L10.8
Has a note

Reduce crosswind limits by 5 kn on wet or contaminator runways whenever engine outthrust is used

57
Q

Which EICAS messages can affect the LVO capability without causing a change on the AFS status annunciation or note in the checklist?

A

Single source displays

(LVO not permitted)

58
Q

What is the minimum auto pilot disconnect height on an ILS approach if land three or land two is not annunciated?

A

200 feet AGL

Note if Land two or Land three is annunciated and manual landing as planned you can disconnect 100 feet RA )

59
Q

After deicing anti-icing, what precaution is to be taken part to takeoff?

A

A pretakeoff contamination inspection.
Good airmanship to do a visual inspection from the cabin of the wings for evidence of contamination or inappropriate hold overtime within five minutes prior to the takeoff

The first or second officer

60
Q

Where can the decode of SNOWTAM be found?

A

OMA

Or Jefferson Flight deck Pro
Publications
General airway manual

61
Q

After I coldweather start with outside air temperature of -20 a generator fault light has illuminated what may be the cause?

A

Cold oil in the CSD and the generator may be slow to produce steady power.
Usually one minute is enough to return to normal, but sometimes five minutes may be required

Inform ATC and hold position

62
Q

For takeoff in low visibility conditions when is it takeoff alternate required?

A

Wen takeoff weather conditions at the departure airport are at or below the published ILS landing minimum or the minimum for the approach and use
(LVO permitted)

63
Q

The destination alternate Airport has Cat 3B capability, is it permissible to file this Airport as an alternate if the weather is marginally below Cat one weather?

A

No.

LVO minimum shall not be used as basis to calculate minimum for filing as an alternate

64
Q

After Dispatch the destination weather forecast indicates LVP will be required. What should the crew consider with respect to the destination alternate?

A

Crew should ensure that the destination ultimate permits Cat one Operations

65
Q

Contaminated runway for landing, what should you considerations be?

A

Use of Max reverse
Effect on crosswind limit
Planned runway exit provides a benchmark for monitoring break effectiveness



66
Q

Given that wind and breaking action is acceptable is autoland permitted on contaminated runways

A

Yes
But auto pilot should be disconnected on rollout if directional control becomes inadequate

67
Q

An eight figure group such as
8849 0594
Is appended to a metar which means what? How do you decode it? 

A

We can now use Air crew tools app
There is a SNOWTAM option
Or
In this case
“ Runway state” option
6 digit or 8 digit

68
Q

What adverse condition might occur during landing when touching down in the touchdown zone of a heavily used runway?

A

Viscous aquaplaning caused by rubber deposits in the touchdown zone significantly reducing runway friction

Reverted rubber

69
Q

ATC information states that 70% of the takeoff runway length has been cleared of contaminant. How does this affect your RTW calculation?

A

More than 25% of the runway is contaminated so the contaminant must be considered (more than 3mm)

Or the reduced runway length will be the accelerating stop distance available without contaminant
(Entered into NOTAM on OPT)

70
Q

If a runway is reported being snow covered with a friction coefficient
of .25 MU
What concerns might you have?

A

Referred to FCOM limitations

0.25 MU means braking action poor.

Not allowed
Or extreme caution must be exercise with regards to Crosswind

71
Q

What thrust options are available for takeoff on a contaminated runway?

A

No AST

TO
TO one
TO2

72
Q

Crossman Landing on a contaminated runway may cause drifted the down side of the runway. What technique should be used to counteract this?

A

Stow the reverse thrust to idle
use braking to regain centreline
once re-entered reengage reverse thrust

73
Q

Above what Crosswind value on a contaminated runway must FCOM be referred to for operational limitations

A

15 knots or greater
