Estimation of the Atmospheric Structure Constants from Airplane Data

Meteorological measurements in the upper troposphere and lower stratosphere were carried out in the past by several high-flying airplanes. It is a common practice to use the temperature spectrum of the time series obtained from these measurements to compute an averaged value (over the flight path) of the temperature structure constant . In this paper time–frequency techniques are used to obtain...

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...

Analysis of Airplane Boarding Times

We model and analyze the process of passengers boarding an airplane. We show how the model yields closed-form estimates for the expected boarding time in many cases of interest. Comparison of our computations with previous work, based on discrete event simulations, shows a high degree of agreement. Analysis of the model reveals a clear link between the efficiency of various airline boarding pol...
