| Coast | action done by the RDPS on a track when radar reports are no longer correlated to the track | ||||||||||||||||||||
| Latitude | a number that indicates the latitude of the current track position with a precision of 1/10,000 of a degree of latitude. i.e., four decimal places. [Units: degrees of latitude, Range: -90.0000 <= latitude <= 90.0000] | ||||||||||||||||||||

| MDC status | an enumerated type with two values: ¡§true¡¨ and ¡§false¡¨ | ||||||||||||||||||||
| Mode A SSR | a four digit octal number transponded by an aircraft | ||||||||||||||||||||
| Mode A SSR code | same as the corresponding data element of a radar report | ||||||||||||||||||||
| Mode A SSR code status | same as the corresponding data element of a radar report | ||||||||||||||||||||
| Mode C Altitude | altitude information transponded by an aircraft derived from the air pressure sensed by the aircraft | ||||||||||||||||||||
| Mode C altitude (pressure corrected) | same as the corresponding data element of a radar report, except that the pressure is corrected using the altimeter setting for a radar source. | ||||||||||||||||||||
| Mode C altitude status | same as the corresponding data element of a radar report | ||||||||||||||||||||
| MSAW status | an enumerated type with two values: ¡§true¡¨ and ¡§false" | ||||||||||||||||||||

| Track quality | an enumerated type with three values: ¡§active,¡¨ ¡§coasting¡¨ and ¡§coasted out¡¨ | ||||||||||||||||||||
| Unique track identifier | a number that uniquely identifies the subject of the update, i.e., the track from which the ¡§track update¡¨ has been derived. [Range: 0 <= unique track identifier < 1000] | ||||||||||||||||||||
