Ground Operations Flashcards
With the seat adjusted, what is the distance of the closest point on the ground that you can see?
44 feet
What can you use as a reference for centerline when taxiing?
inboard screw of the HUD
What can you use as a reference for 25 ft wingtip clearance?
on the outboard engines, use the 5 o’clock (right) or 7 o’clock (left) positions for 10 ft
if looking cross cockpit use the other pilot’s HUD large knob to the cockpit window knob for 25 ft
What can you use as a reference for 10 ft wingtip clearance?
on the outboard engines use the 4 o’clock (right) or 8 o’clock (left) positions for 25 ft
What can you use as a reference for 97 ft from the main gear when taxiing forward?
start the turn when obstacle is at -10 deg down line on the HUD
using full tiller, symmetric engine thrust and no differential braking
What can you use as a reference for 81 ft from the main gear when taxiing forward?
start the turn when obstacle is just above the CDI dots on HUD
using full tiller, asymmetric engine thrust and differential braking
What can you use as a reference for the main gear?
the edges of the -5 down line on the HUD
the top corner of the kick window
the windshield wiper screw for the opposite side
What can you use as a reference for the main gear when positioning for a star turn?
the edges of the -5 down line on the HUD
What is the C-17 backing capability?
at 586,000 lbs, the aircraft can back up a 2% slope at sea level and 90 deg F
How much can the effective gross weight of the aircraft increase during backing?
89,000 lbs
What is the power technique when all engines are over identically prepared surfaces?
frowny face and ~50% N1
What is the power technique when the outboard engines are over unprepared surfaces with the inboards over prepared or debris-free surfaces?
smiley face and ~50% N1
What can be done to minimize compressor stalls?
avoid power settings greater than 65-70% N1 and turn on engine anti-ice
What is a safe backing speed?
3 to 5 knots
When can tire scrubbing occur?
20 deg to 25 deg of nosewheel deflection
at heavier weights it may not occur until 40 deg
What is the required taxiway/runway width to complete a 180 deg turn?
143 ft or 116 ft
What is the required taxiway/runway width to complete a star turn?
90 ft
What is the purpose of an ERO?
to reduce ground time
What should be considered in regards to an ERO location and position?
avoid tailwinds, limit personnel exposure to small arms threats, and plan for a possible immediate departure if attacked
What is the purpose of a combat offload?
expedite ground time or offload without ground support
What should be considered in regards to a combat offload location and position?
taxi surface of 1000’ min in front of the aircraft
1500’ is desired
What can be used to ensure 1000’ for the combat offload?
with TOGA engaged, the bottom of the flight director bank steering bar marks 1000’
