Development of an operational fitness test for the Royal Air Force

Since 2002, the Royal Air Force (RAF) has been working towards developing role-related physical tests for use as an operational fitness test (OFT). The purpose of this study was to establish reliability of the OFT (comprising four tests), investigate gym-based tests as predictors of performance and establish performance standards. Fifty-eight RAF personnel performed the OFT on three occasions. A separate cohort carried out fitness and anthropometric tests before performing the OFT, by way of establishing performance predictors. Documented evidence and views of an expert panel were used to determine OFT standards. Reliability ranged from moderate to good for three tests, with one test (Dig) showing poor reliability. The 95% limits of agreement for the prediction models ranged from good to poor (6.7-34.2%). The prediction models were not sufficiently accurate to estimate confidently OFT performance, but could be used as a guide to quantify likely outcome and training needs.

Unmanned Aircraft Flights and Research at the United States Air Force Academy

The United States Air Force Academy is actively involved in unmanned aircraft research across numerous departments involving many projects, aircraft, government agencies, and experimental programs. The importance of these research projects to the Academy, the faculty, the cadets, the Air Force, and to the defense of the nation cannot be understated. In an effort to be proactive in cooperating with recent concerns from the FAA about the growth and proliferation of UAS flights, the Air Force has implemented several new guidelines and requirements. Complying with these guidelines, directives, and regulations has been challenging to the researchers and research activities conducted at USAFA. Finding ways to incorporate these new guidelines effectively and efficiently is critical to research and participation in joint projects and exercises. This paper explores the nature of research at USAFA current restrictions imposed by the various regulations, the current process, short term solutions, and a long term vision for research into UAS at the Academy.

Local networking at the Royal Bank of Scotland

Data communications facilities are vital if essential banking operations are to be computerized; branches and head offices that are dependent upon terminals and corporate data to fulfil their functions must have access to such facilities. Back-up facilities are also essential if normal bank functions are not to be disrupted should a fault develop. Investigations that led to the installation of Hyperchannel at the Royal Bank of Scotland are described and the problems to which Hyperchannel provided the solutions are examined. The implementation of the system and plans for future development are discussed.
