Abstract

The embodiments described herein relate to dynamically detecting landing gear deployment of an aerial vehicle. A set of flight measurements is dynamically generated and stored. The set of measurements may include altitude, distance to a destination, and airspeed. Each of these measurements is compared to a respective threshold value to produce a landing scenario indication. The comparison includes ascertaining that the vehicle is within a defined above ground level based on the altitude measurement, ascertaining that the vehicle is within a defined distance to a destination based on the distance to a destination measurement, and ascertaining that the airspeed measurement is below a maximum gear extension speed. The produced indication is converted into a landing gear protocol.

Claims (43)

1. A method comprising:

dynamically generating a set of flight measurements of an aerial vehicle, including dynamically obtaining an altitude measurement, a distance to a destination measurement, and an airspeed measurement;

storing the generated set of flight measurements;

comparing each flight measurement to a respective threshold value to produce a landing scenario indication, wherein the comparison comprises:

ascertaining that the vehicle is within a defined above ground level based on the altitude measurement;

ascertaining that the vehicle is within a defined distance to a destination based on the distance to a destination measurement; and

ascertaining that the airspeed measurement is below a maximum gear extension speed; and

converting the produced indication into a landing gear protocol.

2. The method of claim 1 , further comprising implementing the landing gear protocol, including determining that landing gear of the vehicle is in an unsafe position.

3. The method of claim 2 , further comprising activating a warning signal.

4. The method of claim 2 , further comprising automatically deploying the landing gear.

5. The method of claim 1 , further comprising constructing an altitude pattern based on a plurality of generated altitude measurements.

6. The method of claim 5 , wherein the comparison further comprises ascertaining that the vehicle is descending from a cruising altitude based on the altitude pattern.

7. The method of claim 1 , further comprising constructing an airspeed pattern based on a plurality of generated airspeed measurements, and deriving a historical airspeed trend based on the airspeed pattern, wherein the comparison further comprises ascertaining that the derived trend is indicative of an approach to land.

8. A system comprising:

a processing device in communication with memory; and

one or more tools in communication with the processing device, the tools to:

dynamically generate a set of flight measurements, including the functional unit to dynamically obtain an altitude measurement, a distance to a destination measurement, and an airspeed measurement of an aerial vehicle;

store the generated flight measurements in memory;

compare each flight measurement to a respective threshold value to produce a landing scenario indication, wherein the comparison comprises the functional unit to:

ascertain that the vehicle is within a defined above ground level based on the altitude measurement;

ascertain that the vehicle is within a defined distance to a destination based on the distance to a destination measurement; and

ascertain that the airspeed measurement is below a maximum gear extension speed; and

convert the produced indicated into a landing gear protocol.

9. The system of claim 8 , wherein the tools comprise a microcontroller, the microcontroller to integrate the dynamically generated set, wherein the comparison is performed by the microcontroller.

10. The system of claim 9 , further comprising the tools to construct an airspeed pattern based on a plurality of generated airspeed measurements, and derive a historical airspeed trend based on the airspeed pattern, wherein the comparison further comprises the tools to ascertain that the derived trend is indicative of an approach to land.

11. The system of claim 8 , wherein the tools comprise a global positioning satellite (GPS) system, the GPS system to dynamically obtain the altitude measurement and the distance to destination measurement.

12. The system of claim 11 , further comprising the GPS system to integrate the dynamically generated set, wherein the comparison is performed by the GPS system.

13. The system of claim 8 , further comprising the tools to implement the landing gear protocol, including the tools to determine that landing gear of the vehicle is in an unsafe position.

14. The system of claim 13 , further comprising the tools to activate a warning signal.

15. The system of claim 13 , further comprising the tools to automatically deploy the landing gear.

16. The system of claim 8 , further comprising the tools to construct an altitude pattern based on a plurality of generated altitude measurements, and ascertaining that the vehicle is descending from a cruising altitude based on the altitude pattern.

17. A computer program product comprising a computer-readable storage device having computer-readable program code embodied therewith, the program code executable by a processor to:

dynamically generate a set of flight measurements, including the functional unit to dynamically obtain an altitude measurement, a distance to a destination measurement, and an airspeed measurement of an aerial vehicle;

store the generated flight measurements in the memory;

compare each flight measurement to a respective threshold value to produce a landing scenario indication, wherein the comparison comprises program code to:

ascertain that the vehicle is within a defined above ground level based on the altitude measurement;

ascertain that the vehicle is within a defined distance to a destination based on the distance to a destination measurement; and

ascertain that the airspeed measurement is below a maximum gear extension speed; and

convert the produced indicated into a landing gear protocol.

18. The computer program product of claim 17 , further comprising program code to implement the landing gear protocol, including program code to determine that landing gear of the vehicle is in an unsafe position.

19. The computer program product of claim 18 , further comprising program code to activate a warning signal.

20. The computer program product of claim 18 , further comprising program code to automatically deploy the landing gear.
