This evaluation was conducted to define the capabilities and limitations of the March AFB Air Traffic Control (ATC) Communications System in its installed environment at March AFB, California. This evaluation was accomplished in two phases; a ground phase and a flight phase. The ground phase consisted of extensive testing of a representative sample of the ATC communications equipment, commercial/backup power systems, and site surveys. All equipment found out of technical order (TO) specification was identified to local maintenance personnel for corrective action. The ground equipment checks are designed to eliminate equipment degradation as a factor which might adversely affect the data gathered during the flight phase. The flight phase consisted to taxiing on the airfield and flying radial and orbital tracks from the March AFB Tactical Air Navigation (TACAN) facility using a C-140A flight inspection aircraft. Received signal levels (RSLs) were recorded in the aircraft and on the ground to determine the outer limits of communications coverage and the areas of degraded communications coverage within those limits. Analysis of the data provides a composite three-dimensional picture of the communications coverage for the March AFB ATC Communications System.
