Finding The Balance Between Price And Protection: Establishing A Surface-To-Air Fire Risk-Reduction Training Policy For Air-Carrier Pilots, Earl W. Burress Jr.

Journal of Aviation/Aerospace Education & Research

Currently, U.S. air carriers do not provide equipment or training necessary to mitigate the risk posed by surface-to-air fire (SAFIRE) threats. These threats consist of self-guided weapons (infrared shoulder-fired surface-to-air missiles), manually-aimed threats (small arms, recoilless grenade launchers, rockets, and light anti-aircraft artillery), and hand-held lasers. Technological solutions to counter infrared shoulder-fired missiles have been explored, but were rejected due to prohibitive equipment and maintenance costs. A lower cost option, providing air-carrier pilots with SAFIRE risk-reduction training, has not been formally addressed by the air-carrier industry or the U.S. federal government. This effort will use a business concept, the Cost-Benefit …

Investigation Of Passengers’ Intentions To Use High-Speed Rail And Low-Cost Carriers In China, Jing Yu Pan

Doctoral Dissertations and Master's Theses

With a large population, China is an ideal market for high-speed rail (HSR) and low-cost carrier (LCC) services. While HSR has gained substantial market share in China over the past decade, LCCs have achieved only limited market penetration. The potential growth of LCCs in China, however, is promising given the growing travel demand and government policy support. As LCCs expand their service in the domestic market, they are likely to become a strong competitor of HSR. The potential competition between LCCs and HSR justifies the research of passengers’ behavioral intentions to use HSR and LCCs in China.
