1. A system for determining a turnaround time for an aircraft at an airport, the system comprising:
one or more processors;
one or more geospatial databases storing geospatial data, wherein the geospatial data includes a plurality of spatial measurement sets corresponding to the airport where the aircraft is performing a turnaround, wherein each spatial measurement set indicates an area occupied by a unique parking stand of a plurality of unique parking stands at the airport, and wherein each spatial measurement set includes a plurality of points defining a polygon encompassing the area occupied by the unique parking stand;
and
a memory coupled to the one or more processors and the one or more geospatial databases, the memory storing data into a database and program code that, when executed by the one or more processors, causes the system to:
repeatedly transmit an interrogation signal to a transponder of the aircraft, wherein the interrogation signal causes the transponder of the aircraft to automatically transmit a reply signal configured to be utilized to determine aircraft location data of the aircraft;
receive and monitor a wireless data stream including the aircraft location data, wherein the aircraft location data includes at least a current position, a current altitude, a current velocity, and a current position timestamp of the aircraft;
determine the aircraft is commencing the turnaround in response to the current altitude and the current position indicating the aircraft is on a ground, the current velocity being less than a threshold velocity, and the current position and the geospatial data indicating the aircraft is approaching a respective unique parking stand of the plurality of unique parking stands at the airport, wherein the turnaround occurs at the respective unique parking stand;
determine the aircraft is idle based on the current position and the current velocity of the aircraft and determine the aircraft is located within the respective unique parking stand in response to the geospatial data and the aircraft location data indicating the aircraft is within the polygon encompassing the area occupied by the respective unique parking stand;
in response to determining the aircraft is idle and is located within the area the respective unique parking stand, establishing an on-block time of the turnaround as the current position timestamp;
after determining the on-block time, determine the aircraft is moving out of the respective unique parking stand based on the geospatial data and the aircraft location data;
in response to determining the aircraft is moving out of the respective unique parking stand, determine a position timestamp when the aircraft was last idle; and
set the position timestamp collected when the aircraft was last idle as an off-block time of the turnaround.
