Ground Power and Air Conditioning Systems 15 regularly supply ground power to the aircraft, run time increases and maintenance schedules must be accelerated, often leading to an increase in overall maintenance costs. In addition, as the run time of the unit increases, it shortens the product life and requires accelerated component replacement and associated costs.

Ground Power and Air Conditioning Systems 19 A considerable number of ground support equipment vehicles are often operating simultaneously on the ramp to serve aircraft needs at the gate, particularly at commercial service airports. In addition to mobile GPUs and PCA units, there may also be baggage tugs, catering vehicles, fueling trucks, lavatory servicing equipment, deicing equipment, and water cabinets in service on the ramp.

20 Optimizing the Use of Electric Preconditioned Air (PCA) and Ground Power Systems at Airports 2.3.2 Monitoring Equipment Functionality Gate electrification equipment owners and maintainers -- whether they are employed by an airline or the airport -- must be able to determine if the equipment is functioning properly and being put into service.

22 Optimizing the Use of Electric Preconditioned Air (PCA) and Ground Power Systems at Airports If a remote monitoring system is not a component of the gate electrification system's configuration, usage may be monitored by installing a meter at the point where the GPU and PCA units are connected to the terminal.

Interactions between the ground personnel, pilots, and onboard crews remain within the same company, which may improve consistency of communication and use of the gate electrification system, since company policies and procedures apply to all parties.

24 Optimizing the Use of Electric Preconditioned Air (PCA) and Ground Power Systems at Airports 2.5.3 Local Air Quality and Noise Improvements As discussed in Chapter 1, running the APU emits pollutants from the APU exhaust at the back of the aircraft, while increasing associated noise on the ramp.
