Direct Altitude and Identity Readout (DAIR) System

Figure 3-6.—Typical shipboard Mark XII transponder section. program, the Navy, Air Force, and FAA further agreed on specifications for a ground/shore-based configuration called the DAIR system. DIRECT ALTITUDE AND IDENTITY READOUT (DAIR) SYSTEM The DAIR air traffic control system provides several different types of configurations for different user requirements. They are as follows: Type 5, DAIR Type 10, Radar Air Traffic Control Facility (RATCF) DAIR Type 8, Carrier Air Traffic Control Center (CATCC) DAIR Type 12, Amphibious Air Traffic Control (AATC) DAIR Type 13, Shipboard DAIR. The Navy Training Plan (NTP) for the Type 13 system is currently being reviewed for approval. This shipboard DAIR system is scheduled to replace all Type 8 and Type 12 systems in the fleet; however, there is currently no confirmed time for the conversions. We will include the specifics of this system in the first revision of this volume after the NTP is approved and an installation schedule is set. In the meantime, if you would like to find out more about the Type 13 system, contact the instructors who teach the DAIR systems at the Naval Air Technical Training Center, NAS Memphis, Millington, TN. All the types of DAIR systems use an operator (or a team of operators) to control air traffic via display devices. Each operator gathers and assembles information by monitoring and operating display devices. The operators use this information to control air traffic within a given area. DAIR (AN/TPX-42A(V)5) AN/TPX-42A(V)5 gives the air traffic controller rapid, positive identification and altitude data on transponder-equipped aircraft. It is used for ground-controlled approach at shore installations, such as Naval and Marine Corps air stations (NAS, MCAS), radar operational facilities (ROF), and radar air traftlc control facilities (RATCF). At expeditory airfields, the AN/TPX-42(V)5, in a transportable shelter with ASR, is used by Marine Air Traffic Control Squadrons (MATCS). This system operates with a primary radar. The radar supplies synchronizing triggers and azimuth data to the system. The DAIR information is superimposed on the primary radar video. 3-7
