CONFIGURATION
Normal Take-off Thrust
Normal take-off thrust is verified by the fan RPM (N
1 REF
) and is set with thrust levers fully
forward. Refer to Figures 5.05.1 and 5.05.2.
The target value of N
1
at 80 KIAS is N
1REF.
Due to wind strength and direction, altitude and
temperature, the value of N
1
achieved may vary, and up to 80 KIAS it is acceptable to have an
indicated N
1
which is less than N
1 REF
by up to 1%, or which exceeds N
1 REF.
At speeds above 80 KIAS, it is acceptable to have an indicated N
1
which is less than N
1 REF
by
up to 2%, or which exceeds N
1 REF.
Maximum (APR) Thrust
With the thrust levers fully forward, maximum (APR) thrust is obtained automatically when the
APR is armed and if the N
2
differential between engines exceeds 5%.
The APR allows maximum thrust and increases the N
1
up to 1.5%.
APR thrust can also be achieved by pushing the APR ARM and APR O/RIDE buttons with thrust
levers fully forward.
