Abstract

A system and a method include at least one control unit that determines a de-icing time for an aircraft within a de-icing area of an airport, predicts a de-icing time for an aircraft within a de-icing area of an airport, schedules de-icing times for a plurality of aircraft within a de-icing area of an airport, and/or predicts demand for future de-icing operations of aircraft within a de-icing area of an airport.

First claim

What is claimed is:

1. A system comprising:
a historic de-icing datastore configured to store de-icing data including de-icing times for a plurality of aircraft over a predetermined time period, historical weather data including historical weather conditions during the de-icing times, and historical aircraft data comprising a type and size of the plurality of aircraft;
at least one hardware processor;
at least one first control unit executed by the at least one hardware processor to:
(a) determine, based on tracked aircraft position data, a de-icing time for a first aircraft within a de-icing area of an airport, wherein a real time position, altitude, heading, acceleration, and velocity of the first aircraft are detected by an automatic dependent surveillance-broadcast (ADS-B) tracking sub-system and a global positioning sensor of the first aircraft,
(b) receive from a doppler radar of a weather determination sub-system, current weather data indicative of current weather conditions including current temperature, wind speed and direction of precipitation, at an airport and in proximity of the airport,
(c) correlate the current weather conditions with a current time of the de-icing;

an airport mapping sub-system in communication with the at least one first control unit, wherein the at least one first control unit is executed by the at least one hardware processor to receive airport map data including a location of the de-icing area from the airport mapping sub-system, wherein the de-icing area is locatable through global positioning system data;
at least one second control unit executed by the at least one hardware processor to initiate a schedule for de-icing the first aircraft based on a determination that the first aircraft is scheduled to takeoff from the airport, wherein the at least one second control unit is configured to correlate the position of the first aircraft scheduled to takeoff with the airport map data; and
a user interface including a display and an input device, wherein the user interface is communicatively coupled with the at least one first control unit and the at least one second control unit;
wherein the at least one first control unit is further configured to determine a de-icing time for the first aircraft heading to the de-icing area of the airport based on the detected position of the first aircraft and a matching of the first aircraft to the historical aircraft data corresponding to a same or similar aircraft within threshold weather percentage of temperature, wind speed, and precipitation among the historical weather data;
wherein the at least one first control unit is further configured to determine delay by tracking historical de-icing data with the de-icing time for the first aircraft currently within the de-icing area;
wherein the at least one second control unit is further configured to determine a schedule for de-icing one or both of the first aircraft or a second aircraft based on the de-icing time;
wherein the first control unit is further configured to output a first signal including de-icing data regarding the de-icing times, types and sizes of the first aircraft and the second aircraft to the user interface;
wherein the user interface is configured to show the de-icing times, types and sizes of the first and second aircrafts on the display;
wherein the at least one second control unit is further configured to output a second signal including the schedule for de-icing the first and second aircrafts data to the user interface.

2. The system of claim 1 , further comprising the ADS-B tracking sub-system in communication with the at least one first control unit, wherein the ADS-B tracking sub-system is executed by the at least one hardware processor to track the position of the first aircraft at the airport, and wherein the at least one first control unit is executed by the at least one hardware processor to determine the de-icing time for the first aircraft based on the position of the aircraft in relation to the de-icing area.

3. The system of claim 1 , wherein the at least one first control unit is executed by the at least one hardware processor to determine the de-icing time by comparing an entry time of the first aircraft into the de-icing location and an exit time of the first aircraft from the de-icing location.

4. The system of claim 1 , further comprising the weather determination sub-system in communication with the at least one first control unit, wherein the weather determination sub-system is executed by the at least one hardware processor to provide the current weather data.

5. The system of claim 1 , wherein the at least one first control unit is executed by the at least one hardware processor to store the historical de-icing data within the historic de-icing datastore.

6. The system of claim 1 , wherein the at least one first control unit is executed by the at least one hardware processor to further predict a de-icing time for at least one other aircraft within the de-icing area of the airport.

7. The system of claim 6 , wherein the at least one first control unit comprises a de-icing prediction control unit.

8. The system of claim 6 , wherein the at least one first control unit is executed by the at least one hardware processor to predict the de-icing time for the at least one other aircraft based on the historical de-icing data.

9. The system of claim 1 , wherein the at least one first control unit is executed by the at least one hardware processor to further predict demand for future de-icing operations based on the de-icing data.

10. A method comprising:
storing, in a historic de-icing datastore, historical de-icing data comprising: de-icing times for a plurality of aircraft over a predetermined time period, historical weather data including historical weather conditions during the de-icing times, and historical aircraft data comprising a type and size of the plurality of aircraft;
