Precision timing and time interval (PTTI) capabilities are becoming more commonplace throughout the world. The increasing demand for and use of precise time comes with a potentially increasing risk of over-reliance on a single timing source. In addition, many precise time applications are considered critical, in that service disruption could result in severe consequences. The Global Positioning System (GPS) provides PTTI services that meet or exceed most user requirements, at increasingly lower...

Simulators used for total training and evaluation of airline pilots must satisfy stringent criteria in order to assure their adequacy for training and checking maneuvers. Air traffic control and company radio communications simulation, however, may still be left to role-play by the already taxed instructor/evaluators in spite of their central importance in every aspect of the flight environment. The underlying premise of this research is that providing a realistic radio communications...

A forward scattermeter, consisting of transmitter and receiver heads mounted on a fork, is used in the New Generation Runway Visual Range (NGRVR) System to assess the clarity of the atmosphere. The scatter meter is calibrated by comparison with reference transmissometers. The consistency of the calibration from one unit to the next is verified by measuring the fork geometry and using a performance model to predict the expected calibration variation for different forks. The model also assesses...

This report examines the influence of crosswind and other factors on the behavior of wake vortices. Data from acoustic remote sensors and in situ sensors were used to track the possible transport of wake vortices between parallel runways. The measurements used in the analysis came from landing (1976-7) and takeoff (1980) operations at O'Hare International Airport. As expected, wake vortices are observed to transport with the ambient wind; therefore, dangerous wake vortex encounters can be...

Color is probably the most effective, compelling, and attractive method available for coding visual information on a display. However, caution must be used in the application of color to displays for air traffic control (ATC), because it is easy to do more harm than good. The only thing that is truly obvious about the use of color on displays is that its benefits and drawbacks depend upon the task. This paper offers general guidelines on how color should, and should not, be used, but does not...
