The Advantages of Three-Shaft Turbofan Engines for Civil Transport Operation
Published online by Cambridge University Press: 04 July 2016
Extract
The engine parameters which most obviously must improve to contribute to the continued lowering of aircraft Direct Operating Costs are those of prices, weight, volume and fuel consumption. These affect the base-line performance characteristics of the aircraft and in any formula for estimating Direct Operating Costs they will appear in the general cost of flying a load of passengers or freight from A to B.
Engines also unfortunately generate other costs in their own right. These include:
Maintenance labour while mounted on the aircraft.
Repair and overhaul shop labour (including time to remove and re-install the engine).
Replacement parts cost.
Spare engine holding.
Spare parts holding.
Overhaul shop overheads.
