Hugh Pickens writes writes: "The WSJ reports that US airlines are facing their most serious pilot shortage since the 1960s, with federal mandates taking effect that will require all newly hired pilots to have at least 1,500 hours of prior flight experience—six times the current minimum—raising the cost and time to train new fliers in an era when pay cuts and more-demanding schedules already have made the profession less attractive. Meanwhile, thousands of senior pilots at major airlines soon will start hitting the mandatory retirement age of 65. "We are about four years from a solution, but we are only about six months away from a problem.,” says Bob Reding, recently retired executive vice president of operations at AMR Corp. A study by the University of North Dakota's aviation department indicates major airlines will need to hire 60,000 pilots by 2025 to replace departures and cover expansion over the next eight years. Meanwhile only 36,000 pilots have passed the Air Transport Pilot exam in the past eight years, which all pilots would have to pass under the congressionally imposed rules and there are limits to the ability of airlines, especially the regional carriers, to attract more pilots by raising wages. While the industry's health has improved in recent years, many carriers still operate on thin profit margins, with the airlines sandwiched between rising costs for fuel and unsteady demand from price-sensitive consumers. "It certainly will result in challenges to maintain quality," says John Marshall, an independent aviation-safety consultant who spent 26 years in the Air Force before overseeing Delta's safety. "Regional carriers will be creative and have to take shortcuts" to fill their cockpits."
