Overall effective efficiency of jet-propelled flight may be defined as net useful work that is done in accelerating vehicle, raising it to height and combating its drag, divided by calorific value of propellants used; performance figures based solely on cruise performance, such as conventional thrust-work efficiency, are less reliable as guides to overall suitability of particular propulsion system; simple compromise performance figure, which makes allowance for climb and acceleration phase, is recommended.
