An engine thrust management system comprising an engine control device, an aircraft
flight manual, a flight management device and a cockpit instrument device. The
engine control device is operable to calculate a percent maximum available thrust
parameter and a percent indicated thrust parameter. The aircraft flight manual
is operable to calculate a required thrust parameter. The flight management device
is operable to calculate a percent thrust setting target parameter and a percent
commanded thrust parameter. The percent commanded thrust is the amount of thrust
requested by an aircraft operator. The percent commanded thrust is varied by the
operator according to the value of the percent thrust setting target parameter
and the value of the percent indicated thrust parameter in order to produce optimal
thrust. The engine thrust management system promotes operating efficiency by eliminating
redundant processes found in conventional thrust management systems and is applicable
to a wide variety of engines and aircraft, thus promoting common cockpit display architecture.
