High-speed rejected takeoff detection

A method comprising:

• detecting, by a processing circuit, a high-speed rejected takeoff has occurred by determining an aircraft has accelerated to at least a first preset indicated airspeed value and then by determining the aircraft has decelerated below at least a second preset indicated airspeed value and the aircraft is on the ground;
• detecting, by the processing circuit, an event other than the high-speed rejected takeoff has occurred by determining the aircraft has not accelerated to at least the first preset indicated airspeed value, or by determining the aircraft has accelerated to at least the first preset indicated airspeed value and the aircraft has not decelerated below at least the second preset indicated airspeed value, or by determining the aircraft is airborne;
• receiving input data associated with the aircraft, wherein receiving the input data comprises receiving at least one of aircraft location data associated with the aircraft, wind speed and wind direction data at a location of the aircraft, or geospatial data for an airport where the aircraft is located;
• and
• detecting an initial condition using the input data, wherein the initial condition is employed to facilitate one of the detecting the high-speed rejected takeoff or the detecting the event,
• wherein the aircraft location data comprises a current geographic location, a current altitude, a current velocity, and a current position timestamp of the aircraft, and wherein the current velocity of the aircraft comprises a current ground speed and direction of travel of the aircraft, and wherein the method further comprises determining a current indicated airspeed of the aircraft from the current ground speed of the aircraft and the wind speed and wind direction data.

A method comprising:

• detecting, by a processing circuit, a high-speed rejected takeoff has occurred by determining an aircraft has accelerated to at least a first preset indicated airspeed value and then by determining the aircraft has decelerated below at least a second preset indicated airspeed value and the aircraft is on the ground;
• storing high-speed rejected takeoff data in response to detecting the high-speed rejected takeoff;
• detecting, by the processing circuit, an event other than the high-speed rejected takeoff has occurred by determining the aircraft has not accelerated to at least the first preset indicated airspeed value, or by determining the aircraft has accelerated to at least the first preset indicated airspeed value and the aircraft has not decelerated below at least the second preset indicated airspeed value, or by determining the aircraft is airborne;
• storing other than high-speed rejected takeoff data in response to detecting the event other than the high-speed rejected takeoff;
• and
• improving an initial condition trigger and high-speed rejected takeoff detection using at least one of machine learning or artificial intelligence to analyze the high-speed rejected takeoff data and the other than high-speed rejected takeoff data.

A system, comprising:

• a processing circuit;
• and
• a memory associated with the processing circuit, the memory comprising computer-readable program instructions that, when executed by the processing circuit causes the processing circuit to perform a set of functions comprising:
• receiving input data associated with the aircraft;
• detecting an initial condition using the input data, wherein detecting the initial condition comprises:
• detecting the aircraft is on a runway polygon on the ground and starting to move with takeoff acceleration;
• and
• determining the aircraft was on the ground a predetermined number of minutes prior to starting to move;
• detecting a high-speed rejected takeoff has occurred by determining an aircraft has accelerated to at least a first preset indicated airspeed value and then by determining the aircraft has decelerated below at least a second preset indicated airspeed value and the aircraft is on the ground;
• and
• detecting an event other than the high-speed rejected takeoff has occurred by determining the aircraft has not accelerated to at least the first preset indicated airspeed value, or by determining the aircraft has accelerated to at least the first preset indicated airspeed value and the aircraft has not decelerated below at least the second preset indicated airspeed value, or by determining the aircraft is airborne.
