d- all above a, b and c
D
What is reservoir fluid level if both upper and lower sight glasses show dark (A, B1, B2)

What is condition of airplane when we carry out hydraulic system fluid level check (B1)
a- all spoilers down, flap and slat up
b- all spoilers down, thrust reversers stowed, brake surge accumulator precharged correctly and pressurized
c- all spoilers down, all cargo doors closed, all landing gear doors closed
B
When one tire pressure is less than the correct value by more than 20% (B1)
a- we inflate this wheel by nitrogen
b- we replace this wheel assembly
c- we replace this wheel and also the wheel on opposite side of that axle if airplane has moved with this low pressure wheel
C
For tire service we can use (A, B1, B2)
a- nitrogen only
b- nitrogen and air
c- nitrogen or air only if nitrogen not available but we make sure that oxygen content in tire is not more than 5% by volume
A
To check precharge pressure of parking brake accumulator we make sure that (B1)
a- parking brake engaged, center hydraulic system depressurized
b- parking brake released, center hydraulic system and reservoir depressurized
c- right and center hydraulic system depressurized, parking brake released and parking brake accumulator bleed of hydraulic fluid by pushing brake pedals at least 12 times.
B
To check precharge pressure of system hydraulic system accumulators we make sure (B1)
a- all three systems depressurized
b- all three reservoirs depressurized
c- a and b
C
For IDG oil service we need (B1)
a- open l/h fan cowl
b- open access panel on l/h thrust reverser cowl
c- open center thrust reverser latch panel
A
In what conditions can we remove overflow drain hose when we fill IDG oil (B1)
a- when oil just comes out of overflow drain hose
b- when we stop operate filling pump
c- we disconnect pressure line and wait until oil overflow slows to few drops a minute
A
What is correct for IDG oil service (B1)
a- pressure line connected first and overflow disconnected first
b- overflow line connected first and disconnected last ???
c- pressure line connected first and disconnected first
B
For BUG oil service we need (B1)
a- open l/h fan cowl
b- open access panel on l/h thrust reverser cowl
c- open center thrust reverser latch panel
In what conditions can we remove overflow drain hose when we fill BUG oil (B1)
a- when oil just comes out of overflow drain hose
b- when we stop operate filling pump
c- we disconnect pressure line and wait until oil overflow slows to few drops a minute
What is correct for BUG oil service (B1)
a- pressure line connected first and overflow disconnected first
b- overflow line connected first and disconnected last
c- pressure line connected first and disconnected first
Where are brake surge accumulators located (B1)
a- in l/h main gear wheel well
b- in both main gear wheel well
c- rear spar to l/h and r/h landing gear support beams
Where is located parking brake accumulator (B1)
a- forward of right wheel well
b- aft of right wheel well and next to center hydraulic reservoir
c- left wheel well
Where are located hydraulic system accumulators (B1)
a- in both main wheel wells
b- in engine strut bays and l/h main wheel well
c- in aft of stabilizer compartment of airplane
Accumulators can be serviced by (A, B1, B2)
a- air
b- nitrogen only
c- hydraulic fluid
What is correct to check fluid level inside shock strut (B1)
a- measure shock strut pressure and extension twice, at different shock strut extensions
b- deflate shock strut fully
c- check with airplane weight on wheels only
After we did complete oil and nitrogen shock strut servicing (B1)
a- we need check shock strut pressure every week when airplane landed
b- we check shock strut pressure every day for one month
c- we check shock strut pressure between 5-10 landing and do servicing as necessary
