ABSTRACT:
The throttle fuel flow of an aircraft jet engine is controlled by measuring the actual value of an engine parameter demand and measuring the error between the actual value and a value of the parameter demand calculated from a number of engine operating data. The error is then used to drive an integrating fuel throttle value until the error is substantially zero. The engine parameter chosen is the high pressure compressor delivery mach number.
