Abstract
An automatic throttle (A/T) controller (23) for controlling the thrust produced by the engines of an aircraft having a mixture of different types of engines (11a, 11b, . . . 11n) is disclosed. A code that denotes the type and rating is produced for each aircraft engine. If desired other codes, such as a common rating code, a maximum thrust limit code, etc. can be produced. The codes are read by the A/T controller (23) and used to look up engine type and rating data for a controller channel (25a, 25b, . . . 25n) associated with each engine (11a, 11b . . . 11n). In a conventional manner, each channel (25a, 25b, . . . 25n) uses the type and rating data, and common data, if any, to calculate rating limits, throttle control position and throttle limits, plus allocate gains for dynamic control. The calculated parameters control the production of A/T controller signals that, in turn, control the operation of servo motors (19a, 19b, . . . 19n), or some other engine controller, that separately control a position of each engine throttle (17a, 17b, . . . 17n) and associated thrust.
