This article defines some limiting conditions of the specific energy consumption, which are especially important for the energy consumption of civil aircraft, and discusses their influence. Based on a definition of specific energy consumption as the quotient of the energy consumption for a given flight mission and the actual traffic volume, the various possible delimitations of the energy input (primary or end use energy) and its reference values are described. This is followed by an analysis of methods for determining the fuel consumption of aircraft and by a discussion of the influence of real flight conditions on the reference value “traffic volume” (flight route and loading conditions). In conclusion, their impact on the specific energy consumption of aircraft is illustrated by the example of flight from Cologne to Hanover and back with an Airbus A 300 B2. For this purpose a programme for calculating fuel consumption is employed, which takes into account the whole range of factors that have a significant effect on the specific energy consumption. A nomograph is used to represent the results as a function of the load.
