1.A Primary Radar System. ASDE.X sys-tem coverage includes the airport surface and the airspace up to 200 feet above the surface. Typically located on the control tower or other strategic location on the airport, the Primary Radar antenna is able to detect and display aircraft that are not equipped with or have malfunctioning transponders. 2.Interfaces. ASDE.X contains an automa-tion interface for flight identification via all automation platforms and interfaces with the terminal radar for position information. 3.ASDE.X Automation. A Multi.sensor Data Processor (MSDP) combines all sensor reports into a single target which is displayed to the air traffic controller. 4.Air Traffic Control Tower Display. A high resolution, color monitor in the control tower cab provides controllers with a seamless picture of airport operations on the airport surface. b. The combination of data collected from the multiple sensors ensures that the most accurate information about aircraft location is received in the tower, thereby increasing surface safety and efficiency.

The installation of ASDE.X is projected to be completed by 2009. 4.5.6. Traffic Information Service (TIS)a. Introduction The Traffic Information Service (TIS) provides information to the cockpit via data link, that is similar to VFR radar traffic advisories normally received over voice radio. Among the first FAA.provided data services, TIS is intended to improve the safety and efficiency of “see and avoid” flight through an automatic display that informs the pilot of nearby traffic and potential conflict situations. This traffic display is intended to assist the pilot in visual acquisition of these aircraft. TIS employs an enhanced capability of the terminal Mode S radar system, which contains the surveillance data, as well as the data link required to “uplink” this information to suitably.equipped aircraft (known as a TIS “client”). TIS provides estimated position, altitude, altitude trend, and ground track information for up to 8 intruder aircraft within 7 NM horizontally, +3,500 and .3,000 feet vertically of the client aircraft (see FIG 4.5.4, TIS Proximity Coverage Volume). The range of a target reported at a distance greater than 7 NM only indicates that this target will be a threat within 34 seconds and does not display an precise distance. TIS will alert the pilot to aircraft (under surveillance of the Mode S radar) that are estimated to be within 34 seconds of potential collision, regardless of distance of altitude. TIS surveillance data is derived from the same radar used by ATC; this data is uplinked to the client aircraft on each radar scan (nominally every 5 seconds). b. Requirements 1. In order to use TIS, the client and any intruder aircraft must be equipped with the appropriate cockpit equipment and fly within the radar coverage of a Mode S radar capable of providing TIS. Typically, this will be within 55 NM of the sites depicted in FIG 4.5.5, Terminal Mode S Radar Sites. ATC communication is not a requirement to receive TIS, although it may be required by the particular airspace or flight operations in which TIS is being used. 4.5.8 Surveillance Systems FIG 4.5.4 TIS Proximity Coverage Volume FIG 4.5.5 Terminal Mode S Radar Sites Surveillance Systems 4.5.9 FIG 4.5.6 Traffic Information Service (TIS)Avionics Block Diagram 4.5.10 Surveillance Systems 2. The cockpit equipment functionality required by a TIS client aircraft to receive the service consists of the following (refer to FIG 4.5.6): (a)Mode S data link transponder with altitude encoder. (b)Data link applications processor with TIS software installed. (c) Control.display unit. (d)Optional equipment includes a digital heading source to correct display errors caused by “crab angle” and turning maneuvers. NOTE. Some of the above functions will likely be combined into single pieces of avionics, such as (a) and (b). |
