54
How long must you wait after setting the APU MASTER SW pb-sw to ON, before setting the APU START pb to ON?
And why?
5 seconds
These 5 s correspond to the time the ECB needs to power up when the APU MASTER SW pb-sw is set to ON.
55
In the case of an aborted APU start, how long must you wait before a new start attempt?
Why?
60 s
This 60 s period is due to the ECB inhibition logic after an aborted APU start.
56
After three consecutive APU start attempts, how long must the flight crew wait before a new start attempt?
Why?
60 mins
This 60 min period is to allow the APU starter to cool down.

5 min:
Two consecutive cycles of 2 min duration maximum, plus one additional cycle of 1 min, with a run down to zero N3 between each cycle, or
One 5 min cycle.
71
Engine starter. How long Must you wait after the last cycle to allow the starter to cool?
30 mins.
No running engagement of the starter when the N3 is above 10 %on ground, or 30 % in flight.
Note:
High tailwinds (higher than 15 kt) may have an adverse effect on start. It may be necessary to reposition the airplane into the wind.
72
What are the limits of Reverse thrust?
Selection of the reverse thrust is prohibited in flight
Backing the aircraft with reverse thrust is not permitted
Maximum reverse should not be used below 70 kt (or when the indication starts to fluctuate). Idle reverse is allowed down to aircraft stop.
