Cost Efficient on Board Power for Airline Operation,
LUFTHANSA GERMAN AIRLINES HAMBURG (GERMANY F R)
This report provides a brief technical review of airline experience with Auxiliary Power Units APU as influenced by the fuel crisis. Typical APU design features and performance outputs, supplying bleed air andor electrical power on board the airplane are described. The economic impact on APU operation due to fuel cost increase and high level of APU maintenance cost is discussed together with such airline remedies as fuel saving modification programs and reduction of APU operating time. Technical consequences and effects on operating procedures of using alternative power sources are examined with respect to system compatibility with on board power requirements and availability and necessary cost investments. Plans and practical approaches, aiming for optimized, cost efficient onboard power, as seen from an airlines point of view, are provided.
