AOR

Question 1

V1 takeoff performance standard

Answer 1

Attain 35ft over end of runway after engine failure at V1. Also, stop without reverse thrust when an RTO is initiated at V1

Question 2

Why is wind correction to target speed required?

Answer 2

Wind speed is lower close to the ground so airspeed decreases possibly leading to a short touchdown

Question 3

Weather related indications of low level windshear?

Answer 3

TS in vicinity
Passing front with temp difference of 5deg+ moving at 30kts+
Virga

Question 4

Max increase in Vr in potential windshear?

Answer 4

20kts but not greater than the Vr for the performance limited TOW

Question 5

Company standard (critical operation) vs AFM Wet

Answer 5

TH speed: Vref+15 vs Vref
T/D point: 2000ft vs 950ft
Transition time: 3sec vs 0.3sec

Question 6

Wake turbulence info

Answer 6

Heavy, clean, slow is worst.
Max duration of vortex 2-3min
Sink at 400-500fpm to 900ft below flight path
Low vortexes move laterally at 3kts across the ground
Quartering tailwinds cause vortexes to linger near TD point

Question 7

Wake turbulence separation

Answer 7

Same rwy or parallel runways within 2500ft:
Heavy following A380: 6nm on same flight path or 1000ft below
2mins (3mins intersecting) on departure

Heavy following heavy: 4nm

Question 8

Cat 1 runway glidepath requirements

Answer 8

2.5 to 3.25deg

Question 9

Factors that affect holdover time

Answer 9

• Intensity of precipitation
• Configuration, slope, roughness of aircraft surfaces
• Ambient temp and humidity
• Direction, velocity of winds
• Solar radiation
• Aircraft surface temp
• Jet blast

Question 10

Upper wing marking

Answer 10

Only Pax aircraft
60cm x 120cm
Flourescent yellow surrounded by black
use to inspect, such as expiry of holdover time.

Ground crew may inspect upper surface.

Question 11

Hydroplaning

Answer 11

Dynamic: hydroplaning on a layer of water 2.6mm or more
Viscous: thin layer on markings and wheels cannot spin up
Reverted rubber: Bottom layer of rubber heats and melts off. Water vapour pressure caused by friction lifts tyre from runway.

Question 12

Indications of windshear in flight

Answer 12

Below 1000ft, deviations from steady flight in excess of the following:

• 15kts airspeed
• 500fpm v/s
• 5deg pitch
• 1 dot displacement from G/S

Question 13

Doppler RADAR and LIDAR

Answer 13

Radar: can perceive the air current or microburst around airport by measuring doppler shift between outgoing radio frequency and reflected radio frequency in addition to echo intensity. Needs precipitation.
Installed at: NRT, HND, KIX, HKG

LIDAR: Issues windshear alerts and does not require precipitation. NRT and HND

Question 14

Windshear alert

Answer 14

Gain of headwind of 20kts or greater

Loss of headwind of 20-30kts

Question 15

Microburst alert

Answer 15

Loss of headwind of 30kts+

Question 16

Ice crystal risk

Answer 16

• Areas of visible moisture above 22,000ft
• areas above heavy rain
• areas of light to moderate turbulence
• when rain appears above the freezing level due to melting on windows
• when TAT is significantly different than expected (around 0)

Question 17

Most icing occurs:

Answer 17

0deg to -14deg C

Question 18

Landing on slippery runways and taxiing in water or slush

Answer 18

• Shallow landing flaps to avoid damage
• Fly firmly onto runway
• crab landing in crosswind
• speedbrake immediately up
• fly nosewheel on without delay

After landing and taxiing through water or slush, a visual inspection should be completed before retracting flap beyond F20.

Question 19

No2 window lock?

Answer 19

• Lock lever in position and red paint on lock bracket not visible
• “window not closed” decal not visible
• link arm is 90deg to window and red mark is on red mark

can be closed in flight below Vref30+80
May not be possible to close above 250kts

Question 20

Communication block

Answer 20

RADIO TRANSMIT eicas message after 30sec, may auto-cut transmission
Set tx switch to other than radio
When leaving aircraft, regardless of comm block, select ASP to something other than a radio option

Question 21

Fuel freezing- how to prevent and gap between fuel freezing point and when fuel will freeze

Answer 21

• Increase speed
• Change alt to an alt with higher SAT
• Change route to higher SAT

usually 2-3deg beyond fuel freezing point

Question 22

Recommended wx radar tilt in cruise

Answer 22

4deg

Question 23

IRS NAV ONLY

Answer 23

12mins at 15,000ft or above

10mins at 15,000ft or below

Question 24

SNOWTAM

Answer 24

• Max validity 24 hours
• Notifies presence, removal, and hazardous conditions due to snow, slush, ice or water.
• significant changes are : 20mm for dry snow, 10mm forw wet snow, 3mm for slush.

Question 25

How is snow measured on a runway?

Answer 25

Runway divided into 3 segments. Depth measured more than 2 points 2-8m on both sides of the runway centerline. Average snow depth on each segment reported.

Question 26

Windshear avoidance

Answer 26

Delay takeoff or landing

Question 27

Windshear precaution

Answer 27

Takeoff: - high thrust - most extended takeoff flap - longest suitable runway - increase vr Landing: - stabilise ASAP - use shallow flap

Question 28

Actions in windshear?

Answer 28

Perform windshear escape for all conditions except 'go around windshear ahead' which is up to the pilots discretion.

Question 29

VNAV approach glide path

Answer 29

2.75 to 3.77
