Engine operating limits due to wind direction:
Any wind speed within 30° of nose OR >30° of nose with <5 knots windspeed
No Limitations - TOGA thrust may be applied before brakes released, but must be set by 60 KIAS
Engine operating limits due to wind direction:
> 30° in either direction of the nose, windspeed 5-30 knots
A maximum of 75% N1 may be applied before brake release, then set TOGA thrust by 60 KIAS
Engine operating limits due to wind direction:
> 30° of nose and >30 knot windspeed
Only idle/taxi thrust may be applied before brake release, then set TOGA thrust by 60 KIAS
Cranking limits on ground
Start 1: 90 seconds on, 10 seconds off
Start 2: 90 seconds on, 10 seconds off
Start 3 and subsequent: 90 seconds on, 5 minutes off.
After cold start, engine must remain at _______ until oil pressure returns to normal range
Idle
During landing, maximum reverse thrust is prohibited below ______ and reverse idle should be achieved by _______.
