PROJECTS:
Effects of Satellite Imposed Communications DelaysPrior to 1990, the FAA's ATR had a moratorium on the use of satellite communication systems for most air traffic control communications The moratorium was imposed due to the potential danger of lost (stepped-on) messages resulting from the satellite imposed delays. Volpe, with the support of the FAA's Technical Center and the FAA's Southern Region led a study to assess the risk associated with satellite induced delays. The study found a statistically significant increase in "stepons" only at the highest communication workload levels. ATR lifted the moratorium for most applications that did not include, TRACONs, high density center sectors, or sectors that abut major TRACONs. Eric Nadler, Ph.D., Project Manager |
