− A1E engine:
This is a medium thrust level, selectable through the Takeoff
Data Setting procedure, for all engines operating. For engine
durability and economy this mode should be selected if
conditions do not permit use of ALT T/O-1 but do not require
E T/O mode.
EXTENDED TAKEOFF (E T/O)
− A1E engine:
This mode is the highest level, all engines operating, takeoff
mode. For engine durability and economy of operation, this
mode should only be selected when T/O mode is not
authorized. In case of engine failure the ATTCS triggers the
E T/O RSV mode. The E T/O is automatically selected at
FADEC power-up and also at initiation of the Takeoff Data
Setting procedure. E T/O is also automatically selected in flight,
at or below 15000 ft, when the landing gear down and locked is
received by the FADECs on both engines. This mode is also
selected when the T/O button is pushed and the pressure
altitude is greater than 1700 ft above takeoff altitude. The
FADECs will select E T/O mode if the T/O switch is pressed
after takeoff phase, if the T/O switch is pressed and the current
mode is T/O-1 or if the thrust lever is moved beyond THRUST
SET position in flight or after takeoff phase.
TAKEOFF RESERVE (T/O RSV)
− A1P and A1/3 engines:
This mode is the corresponding OEI mode for all engines
operating in T/O mode. The engine will produce the maximum
rated thrust for the existing ambient conditions in this mode.
T/O RSV is automatically selected when ATTCS is triggered
during operation in T/O mode. T/O RSV is also selected if both
engines do not agree on the thrust mode or when the thrust
mode of the remote engine cannot be determined. This mode
will also be selected from the T/O mode, at or below 1700 ft
a
bove takeoff altitude, when the T/O thrust-rating button is
pushed.
NOTE: T/O RSV is manually selected by advancing one or both
TLA above THRUST SET position, regardless of any
mode previously selected.
