Proposal and justification:
(1) PRESENT METHOD:
Currently, when military aircraft come in for arrival at their home base they are vectored for an approach. This vectoring to final takes approximately 15 minutes. The aircraft is descended to a low vectoring altitude and the power setting for the aircraft is set at a higher power setting to maintain a proposed vectoring speed recommended by the aircrafts T.O.
(2) PROPOSED METHOD:
I’m proposing that we implement a high altitude idle descent approach, which would allow an aircraft to stay at idle from the high altitude environment all the way until landing. This idle descent profile would be aircraft specific and base specific.
(3) EXPECTED BENEFITS:
Based on FY05 data the Air Force spent $4.2 billion on petroleum. Using these numbers the Air Force alone could save approximately $87.36 million by using an idle descent profile. This is already being implemented in civilian aviation and saving billions. Why not the U.S. Military?
