Flight Position Response Element

Flight Position elements are returned in responses for the following request type:

Flight Position
Element Cardinality Description
<flightPosition> 0..n Holder element for identification and reported positions for a single airframe.
<flightId>264915620</flightId> 0..1 The unique identifier for the flight (String). If available, this can be used to retrieve detailed status or complete position tracks of the flight.
<callsign>QXE543</callsign> 0..1 The callsign of the flight (String).
<tailNumber>917F</tailNumber> 0..1 The tail number of the equipment for the flight (String).
<heading>133.39037483310972</heading> 0..1 The current heading of the plane in decimal degrees from magnetic north (Double). This is only available if there is more than one position in the track.
<source>ASDI</source> 1..1 The source of the reported positions.
<positions> 1..1 The recent track of positions reported for the flight.
<position> 1..n A recent position reported for the flight.
<lon>-122.27999877929688</lon> 1..1 The reported longitude of the position in decimal degrees (Double).
<lat>47.66999816894531</lat> 1..1 The reported latitude of the position in decimal degrees (Double).
<speedMph>237</speedMph> 0..1 The reported speed of the aircraft at the time of the reading in whole miles per hour (Integer).
<altitudeFt>4000</altitudeFt> 0..1 The reported altitude of the aircraft in whole feet above ground (Integer).
<date>2012-06-05T22:10:00.000Z</date> 1..1 The UTC date and time in ISO-8601 format (yyyy-MM-dd'T'HH:mm:ss.SSSZ).
<course>15</course> 0..1 NEW The direction of travel in degrees relative to geographic north, clockwise (Integer). The range for this data field is -179 to 180.
<vrateMps>6</vrateMps> 0..1 NEW The velocity of ascent or descent (if negative) in meters per second (Integer).
<phase>cruising</phase> 0..1 NEW Description used to indicate the most likely activity of the plane at a given time. Phases include: taxiing, takeoff, landed, landing, climbing, descending, level, cruising, approach, ground, departure.
Not all positions will include a phase.
<stationID>KDEN</stationID> 0..1 NEW The station identifier used by the FAA for ASDI data. Examples: KZLA, KZAB, KZDV.
The ASDI stream consists of a collection of observations from different regional and national tracking systems. Each of these has a separate stationId. A single aircraft may be observed by multiple stations at once, each of which may report a slightly different position due to the inherent inaccuracy of radar. Because of this, trackers showing ASDI streams should either show all signals separately, maintain an affinity between a callsign and single stationId as long as possible, or integrate the different signals.
