display that presented NEXRAD mosaic images, graphic depiction of METARs, and text METARs. One treatment group used
a NEXRAD image looping feature and the second group used the National Convective Weather Forecast (NCWF) product
overlaid on the NEXRAD display. Both of the treatment displays provided a significant increase in situation awareness but,
they provided incomplete information required to deal with hazardous convective weather conditions, and would require
substantial pilot training to permit their safe and effective use.

In this project the development and deployment of systems measuring aircraft activity at airports is considered. This
includes determining the type of aircraft and the type of aircraft activity. The type of aircraft is basic such as helicopter, single
engine, multiengine, and jet aircraft. The different aircraft activities at airports include take-offs, landings, touch and go and
low approach. Accurate counts of aircraft operations are important because the number and types of aircraft operations are
related to airport planning and operation. The objective of this project was to investigate the feasibility of developing an
automatic aircraft operation monitoring system. This involved investigating candidate technologies and developing a
prototype system for monitoring aircraft operations. In large airports with control tower operations, one can readily determine
aircraft operations because the towers are always manned and logs are kept of all operations. This is not true at smaller and
rural airports that may be only manned during certain hours. Some of the issues involved in deploying technologies for
monitoring aircraft operations include: the system must be cost-effective, reliable portable, must operate self-contained in the
field for two weeks, and must be acceptable at airports.

Nondestructive Evaluation of Aircraft and Spacecraft Wiring

Spacecraft, and especially aircraft, often fry well past their original design lives and, therefore, the need to develop
nondestructive evaluation procedures for inspection of vital structures in these craft is extremely important. One of the more
recent problems is the degradation of wiring and wiring insulation. The present paper describes several nondestructive
characterization methods which afford the possibility to detect wiring and insulation degradation in-situ prior to major
problems with the safety of aircraft and spacecraft.

In this project on the first stage (2000-Ol), we continued to develop the previous joint research between the Fluid
Mechanics and Acoustics Laboratory (FM&AL) at Hampton University (HU) and the Jet Noise Team (JNT) at the NASA
Langley Research Center (NASA LaRC). At the second stage (2001-03), FM&AL team concentrated its efforts on solving of
problems of interest to Glenn Research Center (NASA GRC), especially in the field of propulsion system enhancement. The
NASA GRC R&D Directorate and LaRC Hyper-X Program specialists in a hypersonic technology jointly with the FM&AL
