Functional Analysis of Pilot Warning Instrument Characteristics.

摘要

The concept of a pilot warning instrument (PWI) is that a relatively simple and inexpensive device which could be used to aid aviators in the visual detection and evaluation of other aircraft in their vicinity,giving the aviator ample time to select and then make an appropriate collision avoidance maneuver if necessary. Until the present study research on collision avoidance through the use of a PWI has focused primarily on hardware development. The functional analysis of PWI systems that is presented in this report,is intended to disclose the role of the pilot in such systems and to describe the intricate relationships between the pilot,the PWI,and the operational aeronautical environment. Thirteen general functions are defined and illustrated;five performed by the PWI and eight by the pilot. The PWI functions are exemplified by references to hardware systems in use;the pilot functions are described through the use of mathematical models and empirical data. (Author)
