APU fuel saving VS cost of availability of ground carts for cooling Essay

APU fuel saving VS appeal of availability of ground carts for cooling and electricity - Essay ExampleNevertheless, the APU requires a typical forethought plan that costs approximately $50 per hour (John, 2015 210).Considering an aircraft that flies 400 hours in a stratum, the cost of APU fuel would be $80, 000/year. The cost of maintenance would be $20,000. Therefore, the total annual cost of using the APU power generator would $100, 000. However, the cost might vary depending on changes on fuel price and also proletariat charges (Thom, 2014 120). According to Green (2015 216), there argon other expenses that are associated with the use of APU power generators. They have to undergo through a process of approval by the FAA and other governing bodies. This process is very expensive and adds cost to the specified operational costs. Therefore, it is evident that the cost of using APUs is higher than $100, 000 during the first year of use. These expenses are made high due to factors s uch as high expense of the JET-A fuel that is used by the APUs (Williams, 2015 514).On the other hand, the cost of using Ground carts is generally lower compared to that of APUs. The cost of using Ground Power Units varies according to the size of aircraft being serviced and also the overall services postulate (McCartney, 2014 22). The initial cost of a Ground cart ranges between $12,000 and $18,000. However, charges for 400 Hz electricity and pre-conditioned air are administered on hourly rates, and they depend on the group of the aircraft (Middel, 2015 418). Most airports classify aircrafts as size A, size B and size C. For the size A aircrafts, the charges for 400 Hz electricity and pre-conditioned air are $38 per hour and $80 per hour respectively. The charges for size B aircrafts are $66 per hour and $139 per hour for 400 Hz electricity and pre-conditioned air respectively. On the other hand, size C aircrafts are charged $93 per hour and $200 per hour for Hz electricity and pr e-conditioned air respectively (Nielsen, 2013 244). Therefore, considering
