Section 8. Engines & Fire Protection
8.5.2 Throttles
Thrust is set through manual pilot control of the throttles or automatically by the
autothrottle system.
Takeoff thrust is set automatically by the FADEC when the pilot positions the throttles
to the full-forward position.
8.5.3 Autothrottle
When engaged, the autothrottle will control the position of the throttles to regulate
engine thrust consistent with autopilot directed flight attitude and conditions.
8.5.4 Automatic Power Reserve
The PW610F engines incorporate an Automatic Power Reserve (APR) feature that
automatically increases thrust on one engine when the other engine experiences a
loss of power when both throttles are at the takeoff power setting.
APR ARMING
APR arms automatically when both throttles are advanced to takeoff power with both
engines running. Arming of APR is indicated by white APR ARMED text that appears
above the N
allowed for five minutes. Should this five minute time be exceeded a L (R) ENG
EXCEEDANCE warning message appears prompting the pilot to reduce thrust to the
maximum continuous thrust (MCT) setting.
APR DISARMING
Once armed the APR system will remain armed until the throttles are reduced from
the takeoff power setting. APR is also disarmed manually using the 'Manual APR
Disarming/Deactivating' procedure.
MANUAL APR DISARMING/DEACTIVATING
The APR system can be disarmed on ground or in flight with a line select key on the
ENG synoptic page.
