___ seconds after touchdown, AP disconnects

A

AUTOLAND Sequence

Between 1500ft and 800ft RA when Flap is set to 5, AUTOLAND 1 engages. ALIGN and FLARE arm. Parallel rudder self test carried out.

At Approx 800ft RA, NOSE UP TRIM applied to prevent nose-down transient in event of autopilot disconnection

At 150ft RA, ALIGN engages, RLOUT and RETD arm

At 50ft RA, FLARE engages

19
Q

For LVO you need?

A

20
Q

FOs RVR TO limit?

A

600m or more

21
Q

What are the requirements for a TO alternate?

A

Required if unable to return to departure aerodrome

1 hour still air flight time OEI Cruise (250kts)

Based on AC capability

Conditions

  • Met report at / above applicable landing minima +/- 1 hour of ETA
  • if NPA / Circling, ceiling must be taken into account
  • OEI Capabilities taken into account
22
Q

What are the destination aerodrome requirements?

A

Weather reports and / or forecasts at / above applicable planning minima ETA +/- 1 hour

  • RVR / Visibility in accordance with aerodrome operating minima
  • For NPA / circling CEILING MUST BE AT/ above MDH
    OR
    Two destination alternate aerodromes required

if not met info two alternative required

23
Q

Destination alternate requirements?

A

At least one destination alternate required UNLESS:

  • Duration of planned flight from take-off and landing less than 6 hours
  • Two separate runways available/useable at the destination
  • Weather reports and/or forecasts for destination indicated for period of ETA +/- 1 hour will be at least 2000ft or circling height +500ft (whichever is greater) and ground vis > or equal to 5km

Alternate fuel replaced with 15 min holding at 1500ft above destination in ISA conditions (533kg)

23
Q

during LVO any malfunction below 1000ft will lead to?

A

Go Around

Unless auto throttle if you can maintain the speed manually

23

CAT III - 50FT RA, 200M

23
Q

Approach Ban, what is it?

A

Passing 1000ft Auto callout, RVR must be at or above required minima

TDZ RVR is always controlling

  • Midpoint / stop end RVR controlling if reported and relevant

Minimum RVR values

  • Midpoint = 125m or RVR for TDZ if less
  • Stop End = 75m
24
Q

Where part of a taxiway equipped with centreline lighting lies within the ILS sensitive Area or is sufficiently close to the runway that the aircraft on that part of the taxiway would present an obstruction to aircraft landing or taking-off, that part of the taxiway will be identified by alternate centreline lights, which are what colour?

A

Green and Yellow

25

A

Medium

26

A

Alternating Red and white centreline lights

29
Q

What is the minimum RVR for CAT II approach?

A

300m

30
Q
