Investigating the desirability of navy aircraft service life ex / Keating, Edward G; Blickstein, Irv; Boito, Michael; Chandler, Jess   Journal Article

Publication 2014.
Summary/Abstract Building on prior work on optimal replacement of aging aircraft, this paper presents three methodologies to evaluate prospective aviation Service Life Extension Programs (SLEPs) and applies these methodologies to US Navy F/A-18E/F data. While considerable uncertainty remains as to the values of key parameters (e.g. the cost of F/A-18E/F SLEPs), the preponderance of the evidence available at this juncture favors undertaking SLEPs on F/A-18E/Fs rather than replacing them with new Joint Strike Fighters.

Operating Costs of Aging Air Force Aircraft: Adjusting for Aggregate Budget Effects / Trunkey, R Derek   Journal Article
Trunkey, R Derek Journal Article
0 Rating(s) & 0 Review(s)
Summary/Abstract The rate at which operating costs grow as aircraft age is important for setting operating budgets and for deciding when to replace aging systems. While studies using data from the 1990's typically found 1–3 percent real rates of growth in operating costs as aircraft age, studies using data from the 2000's found greater rates, for example in the 4–6 percent range. Growth in the total U.S. Air Force budget during the 2000s appears to explain much of the higher estimated annual growth rates in operating costs per flying hour beyond the growth rate intrinsic to the aging of the fleet.
