The approximate geometric center of all usable runway surfaces.
Industry:Aviation
An on/off filter that allows the conflict notification function to be inhibited for arrival streams into single or multiple airports to prevent nuisance alerts.
Industry:Aviation
Surveillance equipment specifically designed to detect aircraft, vehicular traffic, and other objects, on the surface of an airport, and to present the image on a tower display. Used to augment visual observation by tower personnel of aircraft and/or vehicular movements on runways and taxiways. There are three ASDE systems deployed in the NAS:
: a. ASDE-3-a Surface Movement Radar.
: b. ASDE-X-a system that uses a X-band Surface Movement Radar and multilateration. Data from these two sources are fused and presented on a digital display.
: c. ASDE-3X-an ASDE-X system that uses the ASDE-3 Surface Movement Radar.
Industry:Aviation
AFP is a Traffic Management (TM) process administered by the Air Traffic Control System Command Center (ATCSCC) where aircraft are assigned an Expect Departure Clearance Time (EDCT) in order to manage capacity and demand for a specific area of the National Airspace System (NAS). The purpose of the program is to mitigate the effects of en route constraints. It is a flexible program and may be implemented in various forms depending upon the needs of the air traffic system.
Industry:Aviation
The distance measured from a point-in-space by systems using area navigation reference capabilities that are not subject to slant range errors.
Industry:Aviation
A method of navigation which permits aircraft operation on any desired flight path within the coverage of ground-or space-based navigation aids or within the limits of the capability of self-contained aids, or a combination of these. Note: Area navigation includes performance-based navigation as well as other operations that do not meet the definition of performance-based navigation.
Industry:Aviation
An internally generated program in hundredths of minutes based upon the AAR. AAI is the desired optimum interval between successive arrival aircraft over the vertex.
Industry:Aviation
An Automation Processing capability that compares trajectories in order to predict conflicts.
Industry:Aviation
The adapted distance beyond a facilities boundary defining the airspace within which URET performs conflict detection.
Industry:Aviation
Airspace surrounding a terminal area within which APD is inhibited for all flights within that airspace.
