Abstract

A method and system for handling a missed approach of an aircraft. A group of signals that indicates a go-around maneuver occurring during an approach of the aircraft to land at an airport is detected on a data bus in the aircraft. An alert to an air traffic control system for the airport when the signal is detected. The alert indicates an occurrence of the go-around maneuver, enabling rerouting of air traffic in a manner that enhances safety.

First claim

1 . A system for reporting a missed approach by an aircraft, the system comprising:
a communications interface to a data bus in the aircraft; and a computer system in communication with the communications interface, wherein the computer system operates to detect a group of signals on the data bus that indicates a go-around maneuver occurring during an approach of the aircraft to land at an airport, and sends an alert to an air traffic control system for the airport when the group of signals is detected, wherein the alert indicates an occurrence of the go-around maneuver, enabling rerouting of air traffic in a manner that enhances safety.

2 . The system of claim 1 , wherein the group of signals on the data bus indicates at least one of an initiation of the go-around maneuver, a change in altitude indicating the go-around maneuver, a command to increase engine power for the go-around maneuver, or an increase in engine power indicative of the go-around maneuver.

3 . The system of claim 1 , wherein the group of signals on the data bus indicates at least one of an initiation of a retraction of a landing gear during the approach, a depression of a takeoff-go-around button, advancing of a throttle that is more than expected for landing, an increase in a speed that is more than expected for landing, or taking flaps up during the approach.

4 . The system of claim 1 , wherein the alert comprises:
information selected from at least one of a depression of a takeoff-go-around button, an emergency procedure performed, a warning message, a route discrepancy, an altitude discrepancy, a location of the aircraft, a change in a direction of travel of the aircraft, a change in a thrust, an airspeed beyond a predetermined threshold speed, a landing gear configuration, or a flap configuration.

5 . The system of claim 1 further comprising:
a communications transmitter, wherein the computer system sends the alert to the air traffic control system using the communications transmitter.

6 . The system of claim 5 , wherein the communications transmitter is selected from one of a controller-pilot data link communications transmitter and a satellite communications transmitter.

7 . The system of claim 1 , wherein the computer system is selected from at least one of a computer, a flight management system, an electronic flight bag, a tablet computer, a mobile phone, or a laptop computer.

8 . The system of claim 1 , wherein the air traffic control system is selected from at least one of a computer, a desktop computer, a workstation, a laptop computer, a tablet computer, or a mobile phone.

9 . An apparatus comprising:
a computer system for an aircraft, wherein the computer system detects a group of signals in the aircraft indicating an abnormal flight procedure occurring during flight of the aircraft within a terminal area of an airport and sends an alert to an air traffic control system for the airport indicating an occurrence of the abnormal flight procedure, enabling an action that enhances safety.

10 . The apparatus of claim 9 , wherein the group of signals indicating the abnormal flight procedure indicates at least one of an initiation of a go-around maneuver, a retraction of landing gear during an approach, a change in altitude indicating the go-around maneuver, a command to increase engine power for the go-around maneuver, a deviation from a landing pattern, a deviation from a takeoff pattern, or a depression of a takeoff-go-around button.

11 . The apparatus of claim 9 , wherein the alert comprises:
information selected from at least one of a depression of a takeoff-go-around button, an emergency procedure performed, a route discrepancy, an altitude discrepancy, a location of the aircraft, a change in a direction of travel of the aircraft, a change in a thrust, an airspeed beyond a predetermined threshold speed, a landing gear configuration, or a flap configuration.

12 . The apparatus of claim 9 , wherein the group of signals is detected during one of a landing of the aircraft and a takeoff of the aircraft.

13 . The apparatus of claim 9 further comprising:
a communications transmitter, wherein the computer system sends the alert to the air traffic control system using the communications transmitter.

14 . The apparatus of claim 13 , wherein the communications transmitter is selected from one of a controller-pilot data link communications transmitter and a satellite communications transmitter.

15 . The apparatus of claim 9 , wherein the computer system is selected from at least one of a computer, a flight management system, an electronic flight bag, a tablet computer, a mobile phone, or a laptop computer.

16 . The apparatus of claim 9 , wherein the air traffic control system is selected from at least one of a computer, a desktop computer, a workstation, a laptop computer, a tablet computer, or a mobile phone.

17 . A method for handling a missed approach of an aircraft, the method comprising:
detecting a group of signals on a data bus in the aircraft that indicates a go-around maneuver occurring during an approach of the aircraft to land at an airport; and sending an alert to an air traffic control system for the airport when the group of signals is detected, wherein the alert indicates an occurrence of the go-around maneuver, enabling rerouting of air traffic in a manner that enhances safety.

18 . The method of claim 17 , wherein the group of signals on the data bus indicates at least one of an initiation of the go-around maneuver, a change in altitude indicating the go-around maneuver, a command to increase engine power for the go-around maneuver, or an increase in engine power indicative of the go-around maneuver.

19 . The method of claim 17 , wherein the group of signals on the data bus indicates at least one of an initiation of a retraction of a landing gear during the approach or a depression of a takeoff-go-around button.

20 . The method of claim 17 , wherein the alert comprises:
information selected from at least one of an indication of a depression of a takeoff-go-around button, an emergency procedure performed, a route discrepancy, an altitude discrepancy, a location of the aircraft, a change in a direction of travel of the aircraft, a change in a thrust, an airspeed beyond a predetermined threshold speed, a landing gear configuration, or a flap configuration.

21 . The method of claim 17 further comprising:
rerouting the air traffic in the manner that enhances the safety.

22 . The method of claim 17 further comprising:
changing a takeoff clearance for another aircraft on a runway at the airport based on the alert.

23 . The method of claim 17 , wherein detecting a group of signals and sending an alert are performed by a computer system selected from at least one of a flight management system, an electronic flight bag, a tablet computer, a mobile phone, or a laptop computer.
