ABSTRACT:
An avionic system (102) in which engine thrust rating data is transmitted from electronic engine controllers (108a and 108b) to flight management computer/thrust management computers (120a and 120b) via digital data buses (110a, 110c, and 114) is disclosed. The flight management computer/thrust management computers (120a and 120b) select the proper data set for the specified engine thrust rating upon power-up. If the thrust rating changes, the flight management computer/thrust management computers (120a and 120b) select a new data set corresponding to the new thrust rating as received over the digital data bus (110a, 110c, and 114). This is accomplished without the need to change aircraft wiring. The flight management computer/thrust management computers (120a and 120b) store the thrust rating in nonvolatile memory (126), allowing the flight management computer/thrust management computers (120a and 120b) to use the stored value to initialize relevant settings according to current engine thrust rating.
