Use cases and requirements

Benefit The timely and real-time availability of an asset location in relation to space and time.
The tracking of an aircraft:
• Improves determining the estimated time of arrival (ETA) of an aircraft.
• Improves re-scheduling of aircraft if in-flight delays occur.
• Makes it easier to locate an aircraft in case of an emergency.
• Increases accurate search and rescue response that would significantly reduce the search
and rescue efforts and costs in determining the location of an accident site.
• Allows passengers to know in-flight and in real time their location in space and time.
• May allow passengers awaiting their flight at an airfield to know of an aircraft's real-time
location in space and time.
• May allow airport ground personnel to know where their particular aircraft for service is in
space and time so as to allow for adequate and efficient arrival and departure preparations
and resource allocation.
• May allow maintenance personnel to know where a particular aircraft is in space and time
so as to allow for adequate and efficient preparations for aircraft servicing, resource alloca-
tion and aircraft scheduling and distribution.
• Will allow governmental organizations to automatically track their contracted service pro-
vider's assets in real time allowing for efficient distribution of aerial resources.
• Improves instrument flight rules (IFR) separation, especially in non-radar airspace.
• Improves and increases the visual flight rules (VFR) following coverage.
• Monitors ATC final approach and runway occupancy, reducing runway incursions on the ground.
• Provides information to cockpit with regards to own ship position and that of other aircraft
cockpit display of traffic information (CDTI) in real time.
• Allows ATC to potentially guide aircraft into and out of crowded airspace/airports with
smaller separation standards. This in turn reduces the amount of time the aircraft must
spend waiting for clearances or in holding patterns. Furthermore, this could lead to bene-
fits of reducing pollution and fuel consumption.
Would benefit automatic devices such as:
• airport lighting control automation and operation;
• airport emergency vehicle situational attention provider;
• aircraft spotter alerts;
• noise abatement measurement devices.

Required data Minimum: Aircraft registration, aircraft hardware unit serial identification, time, position (lati-
tude/longitude), altitude.
The cockpit voice data can also be used in determining the last position in case of an accident.

Data sources • ADS-B (traditional and via satellite) or Mode-S transceiver.
• ADS-C.
• FMC messages.
• High-integrity global positioning system (GPS) navigation source or from alternative aircraft
navigational devices (e.g. GLONASS, Galileo, GNSS, IRNSS, QZSS, BeiDou-2, DORIS, etc.).
• Inertial navigation system (INS) – via automated dead reckoning.
• Routine radio position reports.
• Automated celestial navigational systems (ANSs).
(Additional source, but not from A/C data: primary radar.)
