Abstract

A method provides alert information, regarding an aircraft wheel braking system, to an operator of an aircraft during an aircraft landing. An input of a target deceleration rate for the landing aircraft is received prior to the aircraft having landed on a ground surface. At least one sensor electronically collects information relevant to a real-time deceleration rate of the aircraft after the aircraft has landed on the ground surface, and the real-time deceleration rate of the aircraft is calculated. The target deceleration rate is compared to the calculated deceleration rate to determine an effectiveness of the aircraft wheel braking system. A visual, audible, or tactile alert is optionally provided to the operator of the aircraft, and data from this system could also be used as an input for various other aircraft safety systems. A system for performing the method is also provided.

Claims

1. A method of providing alert information, regarding an aircraft wheel braking system, to an operator of an aircraft during an aircraft landing, comprising:

receiving an input of a target deceleration rate for said landing aircraft, said input being received prior to said aircraft having landed on a ground surface;

electronically collecting, via at least one sensor, information relevant to a real-time deceleration rate of said aircraft after said aircraft has landed on said ground surface;

calculating the real-time deceleration rate of said aircraft;

comparing said target deceleration rate to the calculated deceleration rate to determine an effectiveness of said aircraft wheel braking system; and

providing a visual, audible, or tactile alert to the operator of the aircraft if the effectiveness of said aircraft wheel braking system is different than an anticipated amount.

2. The method of claim 1, wherein the real-time deceleration rate of said aircraft includes a composite value including the deceleration rates attributable to at least two of aerodynamic drag of the aircraft, thrust reversal of the aircraft, and wheel braking of the aircraft.

3. The method of claim 1, wherein the anticipated amount is one of a percentage and a range of the target deceleration rate.

4. The method of claim 1, further comprising the steps of:

determining when said aircraft has first landed on said ground surface; and

automatically inhibiting the step of electronically collecting information relevant to the real-time deceleration rate of said aircraft until it is determined that said aircraft has first landed on said ground surface.

5. The method of claim 1, further comprising the steps of:

determining when said aircraft has first landed on said ground surface;

monitoring an amount of time elapsed since said aircraft has first landed on said ground surface; and

automatically inhibiting the step of providing an alert to the operator for a predetermined amount of elapsed time.

6. The method of claim 1, further comprising the steps of:

determining when said aircraft has first landed on said ground surface;

monitoring a distance travelled by said aircraft along said ground surface since said aircraft has first landed on said ground surface; and

automatically inhibiting the step of providing an alert to the operator for a predetermined amount of distance.

7. The method of claim 1, further comprising the steps of:

determining when said aircraft has first landed on said ground surface;

monitoring a speed of said aircraft along the ground surface; and

inhibiting the step of providing an alert to the operator when said speed of said aircraft is below a predetermined value.

8. The method of claim 7, further comprising the steps of:

electronically recording, in a computer-readable memory, the target deceleration rate for said landing aircraft, at least one calculated real-time deceleration rate of said aircraft, and at least one alert provided to the operator of the aircraft,

wherein said electronic recording occurs after said speed of said aircraft is below a predetermined value.

9. The method of claim 1, wherein the step of receiving an input of a target deceleration rate comprises the steps of:

receiving an input of an automatic braking system (ABS) setting for said aircraft; and

determining the target deceleration rate for said aircraft by correlating said input automatic braking system (ABS) setting with a predetermined deceleration rate for said aircraft.

10. The method of claim 1, wherein the step of electronically collecting information relevant to the real-time deceleration rate of said aircraft is performed by an independent electronic device that is in physical connection with said aircraft but is not in electronic data communication with said aircraft.

11. The method of claim 10, wherein the independent electronic device comprises said at least one sensor, and wherein the information relevant to the real-time deceleration rate of said aircraft is collected in situ by said independent electronic device.

12. The method of claim 11, wherein said at least one sensor includes at least one of an accelerometer and geographical location sensor.

13. The method of claim 12, wherein said geographical location sensor comprises a Global Positioning System (GPS) receiver.

14. The method of claim 1, wherein the step of providing an alert to the operator of the aircraft includes an indication that the calculated the real-time deceleration rate of said aircraft is less than the target deceleration rate for said landing aircraft.

15. The method of claim 1, wherein the step of providing an alert to the operator of the aircraft includes an indication that a preselected automatic braking system (ABS) setting is insufficient to achieve the target deceleration rate for said landing aircraft.

16. The method of claim 1, wherein the step of providing an alert to the operator of the aircraft includes at least one of an indication to increase thrust reversers, an indication to increase aerodynamic drag, and an indication to increase wheel braking strength of the aircraft.

17. The method of claim 1, wherein said ground surface is a runway.

18. A system for providing alert information, regarding an aircraft wheel braking system, to an operator of an aircraft during an aircraft landing, comprising:

a data collection module configured to receive an input of a target deceleration rate for said landing aircraft prior to said aircraft having landed on a ground surface, and to electronically collect information relevant to a real-time deceleration rate of said aircraft after said aircraft has landed on said ground surface;

an analysis module in signal communication with the data collection module configured to calculate the real-time deceleration rate of said aircraft based upon said collected information, and to compare said target deceleration rate to the calculated deceleration rate to determine an effectiveness of said aircraft wheel braking system; and

a feedback module in signal communication with the analysis module that is configured to output a visual, audible, or tactile alert to the operator of the aircraft if the effectiveness of said aircraft wheel braking system is different than an anticipated amount.

19. The system of claim 18, further comprising an independent electronic device that is in physical connection with said aircraft but is not in electronic data communication with said aircraft, comprising said at least one sensor including at least one of an accelerometer and geographical location sensor,
