This report presents the results of the FogEye UV Sensor/System Evaluation for Phase II, which examined trip-wire sensors for detecting aircraft and other vehicles on the airport surface. The test configurations were set up to evaluate the sensor as a runway incursion detection device. The dynamic response of the device was evaluated as well as its performance in fog.

The U.S. Congress asked the Federal Aviation Administration to investigate the feasibility of applying FogEye technology to aviation-related problems. This report presents results of the FogEye UV Sensor/System Evaluation for Phase I, which compared the measurements of a FogEye transmissometer to those of visible light transmissometers.

The purpose of this report is to document the remaining activities since August 1996 that were needed to: 1- determine the best fog calibration for the national deployment forward scattermeter, and 2- Verify that the production tolerances were good enough to meet the specified limit on unit-to-unit variation in the fog response.

This report addresses the wake-turbulence separation standards for close-spaced parallel runways. Ground-wind anemometer data collected at Kennedy (landing) and O-hare (takeoff) airports are analyzed to assess the lateral transport probability for wake vortices.
