Use when you must compute the operating point of a reciprocating high-speed compression-ignition aircraft powerplant: the air-standard dual-cycle thermal efficiency from the compression ratio, the specific-heat ratio, the pressure ratio of the constant-volume heat-addition phase and the cutoff ratio of the constant-pressure phase, the isentropic compression temperature ratio and state temperatures, the four-stroke indicated and brake power from the indicated mean effective pressure, displacement, crankshaft speed and mechanical efficiency, and the brake specific fuel consumption on Jet-A.
