Systems and methods for dragging brake detection

1. A method comprising:

calculating, by a brake controller, a slip ratio based upon an aircraft speed and a speed of an aircraft wheel;

determining, by the brake controller, that the slip ratio is above a threshold value; and

sending, by the brake controller and in response to the slip ratio being above the threshold value, a dragging brake signal to an aircraft component,

wherein the calculating is in accordance with the equation

2. The method of claim 1 , wherein the aircraft component is a pilot notification system.

3. The method of claim 1 , wherein the calculating is performed by an antiskid module of the brake controller.

4. The method of claim 1 , wherein the aircraft speed is determined based upon a speed of a second aircraft wheel.

5. The method of claim 1 , wherein the determining occurs in response to the aircraft speed exceeding 40 knots.

6. The method of claim 1 , further comprising calculating an inaccuracy of the slip ratio.

7. The method of claim 6 , further comprising determining whether the inaccuracy is above an inaccuracy threshold value.

8. The method of claim 1 , further comprising calculating an amount of heat energy absorbed by a brake of the aircraft wheel.

9. The method of claim 8 , further comprising alerting a cockpit component to indicate a need for brake temperature determination.

10. A system comprising:

a brake controller in communication with an aircraft wheel speed sensor; the aircraft wheel speed sensor in communication with an aircraft wheel;

wherein the brake controller:

calculates a slip ratio based upon an aircraft speed and a speed of the aircraft wheel;

determines that the slip ratio is above a threshold value; and

sends, in response to the slip ratio being above the threshold value, a dragging brake signal to an aircraft component,

wherein the calculating is in accordance with the equation
