A unified analytical treatment of the cruise performance of subsonic transport aircraft is derived, valid for arbitrary gas turbine powerplant installations: turboprop, turbojet and turbofan powered aircraft. Different from the classical treatment the present report takes compressibility effects into account on the aerodynamic characteristics. Analytical criteria are derived for optimum cruise lift coefficient and Mach number, without and with constraints on the altitude and/or the engine rating. A simple alternative to the Breguet range equation is presented which applies to aircraft cruising at constant altitude and a high Mach number. A practical non-iterative procedure for calculating the mission and reserve fuel loads in the conceptual design stage is proposed as a conclusion of this report.
