The vulnerability of commercial aircraft avionics to carbon fibers

Avionics components commonly used in commercial aircraft were tested for vulnerability to failure when operated in an environment with a high density of graphite fibers. The components were subjected to a series of exposures to graphite fibers of different lengths. Lengths used for the tests were (in order) 1 mm, 3 mm, and 10 mm. The test procedure included subjecting the equipment to characteristic noise and shock environments. Most of the equipment was invulnerable or did not fail until extremely high average exposures were reached. The single exception was an air traffic control transponder produced in the early 1960's. It had the largest case open area through which fibers could enter and it had no coated boards.

Aircrew displays and avionics for application in a future national airspace system

A concept for increased pilot involvement in a future National Airspace System was evolved during the FAA New Initiatives in Engineering and Development Users responsibilities and ways in which they might interact. The technical feasibility of the system is indicated by the sophisticated level of presently manufactured digital computers and display avionics, and the application of that technology under design by the major airframe manufacturers. Data collected during simulations and flights with the Terminal Configured Vehicle Program B-737 airplane are shown to have direct application to the new system concept. The adoption of the operational changes envisioned, offers some potentially significant advantages to the user.

An evaluation of some display parameters for an advanced landing display

This paper discusses the results of a series of tests conducted to better understand some of the design parameters related to presenting an aircraft landing display on a cathode ray tube (CRT). The study was conducted on an aircraft simulator and the results were evaluated in terms of touchdown performance, pilot control activity, and scanning behavior, that is, how the pilot used the display. The results of the study indicate that magnification, presentation of symbols representing aircraft state, and whether the display is presented in a conventional CRT head-down configuration or a collimated head-up configuration, all play a role in the pilot's performance.

Avionics and displays in a future airspace system

The terminal configured vehicle (TCV) program was conceived to address the problems of (1) operation in the crowded terminal area airspace, and (2) integration of airborne avionics systems necessary to improve the efficiency of these operations. The program and its interaction with industry task groups are summarized, including elements of research and data collection. New technology is discussed which may be useful in implementing some defined avionics and display requirements.

Flight experiments to improve terminal area operations

A brief description is given of the objectives and activities of the terminal configured vehicle (TCV) program and of some of the airborne facilities. A short analysis of some particular problems of CTOL operations in the terminal area is also presented to show how the program's technical objectives are related to the defined problems. The test aircraft was flown both manually and automatically with manual monitoring over paths including 130 deg intercepts and 2.0 km (1.1. n. mi.) and 0.8 km (0.44 n. mi.) finals. Some statistical data are presented from these and other flight profiles designed to address specific terminal in the next biennium and their application to the terminal area. A description of work being undertaken to study the addition of adjacent traffic information to present map displays is also given.

Measuring internal dimensions of small transparent objects

Technique individually photographs first the orifice in the transparent object and then a microscopic scale immersed in a liquid having the same index of refraction as the transparent object. Using a scale photograph, the orifice photograph is measured.
