A flight performance data system comprises a control and display unit operably connected to a computer. The computer has input means responsive to real air mass parameters and real aircraft dynamic measurements. The computer is programmed to respond to the incoming signals and automatically generate various output signals representing flight profile data. A mode selector is operably connected to the computer to direct the computer in different modes to determine the different flight profile data for the climb, cruise, descent and other modes of the aircraft. For various modes, a different flight schedule can be determined corresponding to the most fuel efficient flight, a long-range cruise flight, or the most economical flight. In addition, the computer produces output signals corresponding to the maximum rate of climb and the maximum rate of descent in the climb and descent modes, respectively. A display screen selectively displays the desired flight profile data. In addition, given desired variables can be supplied by the pilot to the computer and the computer automatically generates an output signal corresponding to the flight profile data consistent with the desired variables.
