Electronic Distribution of Airplane Software and the Impact of Information Security on Airplane Safety

The general trend towards ubiquitous networking has reached the realm of airplanes. E-enabled airplanes with wired and wireless network interfaces offer a wide spectrum of network applications, in particular electronic distribution of software (EDS), and onboard collection and off-board retrieval of airplane health reports. On the other hand, airplane safety may be heavily dependent on the secu...

The NASA Landing Gear Test Airplane

A tire and landing gear test facility has been developed and incorporated into a Convair 990 aircraft. The system can simulate tire vertical load profiles to 250,000 lb, sideslip angles to 15 degrees, and wheel braking on actual runways. Onboard computers control the preprogrammed test profiles through a feedback loop and also record three axis loads, tire slip angle, and tire condition. The ai...

Conceptual Blending and Airplane Navigation

Fauconnier and Turner’s conceptual blending theory (1998) has been used to analyze many types of cognitive phenomena, particularly the role blending plays in language comprehension. In this paper we illustrate how blending also has a role in mediating expert performance, such as understanding the meaning of a chart or a navigation display. Pilots use blends to assess flight situations, predict ...

Parallel Numerical Airplane Wing Design

A parallel numerical optimization method for the airplane wing design has been established The extension of traditional Evolution Strategies by new and alterna tive methods combined with a load management for parallel processes leads to the MEPO optimization system The concept of the system allows bene cial usage of parallel processing features for running the optimization algorithms as well as...
