Q

IF SNOW OR CONTAMINATES ARE PRESENT WHAT SHOULD BE DONE ON TAXI IN?

A

FLAPS/SLATS should not be retracted as to prevent damage by crushing ice. A visual inspection shall be performed once on stand then if free of ice retraction can be done.

Q

IN LVO’S WHAT IF YOU HAVE AN A/C FAILURE PRIOR TO LANDING?

A

ABOVE 1000’ - resolve by 1000’ or go around. amend DH if appropriate

1000’ to AH (100’) - any failure leading to downgrade of FMA implies a go-around.

200’ RA & below - RED AUTOLAND requires immediate go-around

100’ (AH) - continue except RED autoland

QRH-SI-20

17
Q

DIFFERENCE BETWEEN FAIL-OPERATION AND FAIL-PASSIVE?

A

FAIL-OPERATIONAL failure below AH (100’), approach, flare & landing completed automatically.

FAIL-PASSIVE AP will disconnect with no significant out of trim but landing will not be automatic. Pilot MUST assume control and land if visual references allow and is safe to do so.

18
Q

WHAT IS THE APPROACH BAN?

A

An approach may be attempted as long as the required RVR is above minimums. If not then you must not continue past 1000’. If you are through 1000’ and then the RVR changes you can continue to land as long as it is safe to do so.

19
Q

WHAT TRIGGERS THE RED AUTOLAND WARNING LIGHT?

A

Activates when at least 1 RA reads below 200’ & 1 AP engaged

  • LOC exceeds 1/4 dot
  • GLIDE EXCEEDS 1 dot
  • LOSS LOC signal
  • LOSS of GLIDE above 100’
  • RA’s have a difference of 15’+
  • last AP disconnects
  • LONG FLARE detected by FMGS
  • UNTIMELY/LONG FLARE detected by FMGS

FCOM-DSC-22

20
Q

WHAT ARE THE APP CATEGORY MINIMAS AND VISUAL REFERENCES?

A

CAT 1 - 200AAL & 500M RVR. Elements of the APP light system, threshold, PAPI R/WAY edge lights.
(LTS -CAT 1 DA AND 400/450M RVR)

CAT 2 - 100’RA, 300M RVR. 3 consecutive lights and lateral element
(OTS CAT 2 - 100’RA, 350M RVR)

CAT 3 A - 50’ RA, 200M RVR. 3 consecutive lights.

CAT 3 B - 75M RVR. NONE (1 light with DH)

21
Q

WHAT IS THE DIFFERENCE BETWEEN LVO AND LVP?

A

LVP - Airport based procedures (=<200’ ceiling & RVR =<600M)

LVO - A/C based procedures

22
Q

WHAT IS THE CONTROLLING RVR?

A

TDZ

but if MID & STOP POINT reported then they are also controlling.

For CATIIIB without DH only 1 RVR required on the airport.

OMA 8.4.4

23
Q

ON A AUTOLAND WHAT HAPPENS BELOW 1000’ WITH REGARDS TO TASK SHARING AND A/C STATUS?

A
  • 1000’ fully configured and stable
  • 800’ LANDING INHIBIT (inhibits some warnings/cautions
  • 700’ FMGC data lock
  • 500’ STABLE
  • 400’ FCU lock
  • 350’ LAND FMA
  • 200’ AUTOLAND RED light active
  • 100’ CALL “ONE HUNDRED” reply “CONTINUE”
  • 40’ FLARE FMA
  • 30’ THR IDLE FMA
  • 10’ ROLLOUT
24
Q

IN TERMS OF ACTIONING A GO-AROUND ON A AUTO LAND TALK ABOUT MANAGEMENT OF A DOWNGRADE

A

ABOVE 1000’ - go-around unless problem rectified or amend DH

BELOW 1000’ - GO-AROUND

200’ or BELOW - GO-AROUND for red AUTO LAND

100’ OR BELOW continue unless red AUTOLAND

Q

TALK ABOUT THE R/WAY CENTRELINE LIGHTING IN THE LAST 900M

A

First 600m red/white

Final 300m red

26
Q

WHAT IS THE MINIMUM OIL TEMP FOR ENG START & T/OFF ON A NEO AND CEO?

A

NEO
-40c start
+19c t/off

CEO

  • 40c START
  • 10c T/OFF

28
Q

WHERE CAN YOU FIND THE HOLDOVER TIMES FOR DE-ICING?

A

Operational Quick Access
+
Cold Weather Quick Reference

29
Q

WHEN DOES THE HOLDOVER TIME START?

A

FROM THE BEGINNING OF THE FLUID APPLICATION

IF 2 step then from the beginning of the 2nd step

30
Q

WHERE CAN YOU FIND THE SNOWFALL INTENSITIES CHART?

A

A

TYPE 1 DILUTED

WINTER OPS MANUAL 2.7.11

32
Q

WHEN SHALL A PRE-T/OFF CONTAMINATION CHECK BE DONE AND WHY?

A

After HOT (Hold Over Time) has been exceeded and it shall be done pre-take off. NO contaminates shall be present.

WINTER INFO HANDBOOK 4.1

33
Q

WHAT HAPPENS IF YOU HEAR THE “CAVALRY CHARGE” AND THE AUTOLAND LIGHT ILLUMINATE?

A

AP has disconnected, MANUAL input needed for a go-around if visuals are not suitable for landing

34
Q

ON A CONTAMINATED R/WAY WHAT SELECTION OF THRUST SHOULD BE USED FOR LANDING?

A

The crew must select MAX REV THRUST

FCTM PR-NP-SOP-250

35
Q

WHAT SCENARIOS WOULD REQUIRE ENG IGN FOR TAKEOFF?

A
  • STANDING WATER
  • HEAVY RAINFALL
  • SEVER TURBULENCE

OMB 2.3.11

36
Q

WHAT IS CAT 3A MINIMA?

A

50-100 ft & 200 m

OMA 8.4.11

37
Q

WHAT IS THE LATEST AN AIRPORT WILL INITIATE LVP’s?

A

Ceiling =<200ft or =<600m

38
Q

WHAT IS MEANT BY THE AKWRT HEIGHT?

A

Above touchdown zone and Alert Height if activated a go around is required.
Below alert height, if failure occurs, flare touchdown & roll out may be accomplished using remaining automatic system (fail operational)
