A performance advisory system for use in optimizing aircraft performance comprising: (a) a display unit for displaying to the pilot recommended flight parameters; (b) a control unit including means for selecting a mode of aircraft operation for which recommended flight parameters are required; (c) means for converting and multiplexing inputs from aircraft sources indicating actual operating parameters, which inputs comprise a plurality of inputs in analog form, another plurality in analog synchro form and further plurality in digital form comprising: (i) an analog multiplexer having a plurality of data inputs and a single data output and an address input, said analog parameters being coupled to the data inputs of said analog multiplexer; (ii) an analog to digital converter having its input coupled to the data output of said analog multiplexer; (iii) a random access memory having a data input, a data output and an address input the data input of said random access memory coupled to the output of said digital to analog converter and the data output of said memory coupled to said computing means; and (iv) a cyclic address generator for cyclically addressing each of the inputs to said analog multiplexer having an output coupled to both said analog multiplexer address input and said random access memory address input, whereby the data present at the data inputs to said analog multiplexer will be successively loaded into locations of said random access memory; and (d) computing means including at least a central processing unit and a fixed program memory having as inputs the outputs from said control unit indicating the mode of operation and said digital information, for solving the flight equations for the aircraft on which said system is installed, said computing means providing recommended flight parameters as outputs which are coupled to said display unit.
