What it does
ASSC improves surface surveillance and situational awareness in all kinds of weather. ASSC is similar to a prior system deployed in the U.S. called the Airport Surface Detection Equipment, Model X (ASDE-X), which is deployed at 35 airports. See http://www.faa.gov/air_traffic/technology/asde-x for more information about ASDE-X.
With ASSC/ASDE-X, controllers see aircraft and ground vehicles on the airport surface, and on approach and departure paths within a few miles of the airport.
- Helps prevent runway collisions
- Improves situational awareness
- Covers airport from arrival through departure paths within a few miles of the airport
- Correlates flight-plan information with position displays
- Provides surveillance data with an accuracy and update rate suitable for:
- Situational awareness in all weather conditions
- Departure queuing
- Conflict detection and alerts
- Taxi route conformance monitoring
How it works
The ASSC system receives input from:
- ASDE-3 surface movement radar
- ASSC multilateration remote units
- Airport Surveillance Radar/Mode-S
- Terminal automation for the flight plan data
ASSC fuses this data to produce a highly accurate display for controllers to show aircraft and ground vehicles on the surface movement area, and on arrival and departure routes. Pilots with TIS-B and cockpit displays can also receive data derived from ASSC.
ASSC data is also transmitted to other FAA systems, including SWIM, and Runway Status Lights.
ASSC is operational at San Francisco and Cleveland. Over the next few years, it will be implemented at:
- Kansas City (MCI)
- Cincinnati (CVG)
- Portland (PDX)
- New Orleans (MSY)
- Pittsburgh (PIT)
- Anchorage (ANC)
