Abstract : Knowing that the APU is the most expensive support device, the temptation is strong to entirely remove it from commercial transports. Adverse consequences of such action include: Loss of the APU puts the burden on the ground equipment, of which the maintenance at the line stations sometimes leaves much to be desired; For some stations the removal of the APU could require a sizeable investment of ground support equipment; Loss of ability to start engine during or after push-back; Increased engine operating time at the gate; Engines have to be kept running after arrival until ground equipment is hooked up; and The risk of deficient comfort for passengers at certain stations in hot or cold weather. The author concludes that KLM cannot permit the removal of the APU since this is the only device that provides prompt and reliable service, independent of other facilities.
