When will the RAT light turn green?
If deployed and PSI is >1500 psi
Which air driven pump will operate if both are turned on?
C1 demand pump
Can two ADP’s operate at the same time?

What is the maximum degrees the nose wheel can turn?
70 degrees
What is the maximum degrees the rudder pedals can turn the aircraft?
7 degrees either side
How is the landing gear numbered?
When does main gear aft steering activate?
When steering angle exceeds 13 degrees
When will RTO braking activate? 3 items
- RTO selected
- Ground speed above 85kts
- Thrust levers retarded to idle
When the flaps & slats are in the normal mode, how are they powered and by what system?
Hydraulically, center system
When the flaps & slats are in the secondary or alternate mode, how are they powered and by what system?
Electrically by secondary electric drive motors
In secondary mode are the flaps & slats limited in range?
Yes, slats limited to the mid range and flaps extended to F20
Will secondary mode be automatically selected for the flaps and slats? What about alternate mode?
Yes. continue using the flap level
Alternate mode has to be manually selected
How does the autoslat operation work?
It is designed to improve stall characteristics by fully extending the slats if F1,5,15,20 are selected and there is a signal from the stall warning
When is WAI inhibited?
- When selected ON and TAT is above 10’c it is limited to 5 minutes after T/O
- If in AUTO, when T/O mode is selected and less than 10 minutes has elapsed
If SATCOM is not working will you be able to receive ACARS data in Japan airspace?
No because VHF data is blocked due to the prohibited cost. Normally this data is reformatted for SATCOM and it may be slower than normal.
From what height will the PWS give an alert on landing?
1200’ RA
