GROUND OPS

Question 1

Set CABIN PRESS CONTR SYS

Answer 1

System will calculate a press schedule

Question 2

Setting intermediate FLT ALT?

Answer 2

workload
higher CABIN ALT
RIsk of driving CABIN to MAX DIFF

Question 3

Intermediate FLT ALT SETTING = higher cabin ALT, why?

Answer 3

Press schedule for lower ALT use lower differential pressure limits.

Question 4

TO Briefing done when?

Answer 4

ASAP

Question 5

Idle Revere during taxi?

Answer 5

slippery surfaces may be needed for control

Question 6

Carbon Brake Life?

Answer 6

One firm application causes less wear than several light applications.

Question 7

Pilot seat position?

Answer 7

1.6m front Nose gear
17.1/18.9 m front Main gear

Question 8

90 deg turn or more?

Answer 8

turn - exit point - centre of nr 3 window. - full nose wheel steering displacement - adjust steering - keep NW outside of taxiway centreline - near outside radius of turn. near turn complete - main gear clear of inside radius - gradually release steering wheel input -

Question 9

Sharp Turns TO a Narrow Taxiway?

Answer 9

Place AC far side / edge surface area.
more room for inbound gear

Question 10

Turn 180deg?

Answer 10

Might need observers - monitor wheel path.
Be aware of surroundings -
More thrust needed - jet blast
Keep gear close to edge, but Engine Nacelles over prepared surfaces
painted RW marking - slippery when wet.
Stop AC with thrust IDLE.
NWS MAX STEERING ANGLE
release brakes
add thrust outboard engine.
5-10kts in turn
Light intermittent brake - inside gear
passing 90deg - place main gear pm CL.
gradual reduce NWS input

Question 11

Turn - nose gear skids?

Answer 11

inside wheel brake briefly + ass thrust

Question 12

180 with larger area?

Answer 12

no need to stop

Question 13

TAxi - adverse weather?

Answer 13

more awareness of surface condition.
strong CW - reduce speeds
Use Diff thrust - keep momentum in turn
near turn complete - engines idle - reduce nose gear skidding.
Diff braking maybe more effective than NWS on slippery surface
Engine exhaust - form ice no ramp etc. or blow snow/slush which can freeze on AC surface.
Taxi route slush/standing water low temps, or if prec falling temps below freezing - taxi flaps up.

Question 14

Slippery surface?

Answer 14

any surface braking capability less than that of DRY.
WET or contaminated with ice, standing water, slush, snow etc
