THRUST RATINGS
The engine control system schedules the corrected fan speed as a
function of pressure altitude, Mach number, ambient temperature, anti-
ice system condition, thrust mode, and thrust lever angle to achieve
the rated thrust conditions.
Thrust ratings modes for AE 3007 engines are:

(**) For A1E engines, E T/O RSV and T/O RSV modes are not
intended for normal operation. Their use must be recorded in the
maintenance logbook or be tracked by use of engine health monitoring.
For the respective takeoff rating, altitude, and Mach-number condition,
fan speed is controlled to maintain constant thrust at any given
ambient temperature below the flat-rated ambient temperature.
