Runway Traction Estimation and Reporting System

A method for runway traction estimation and reporting comprising:

• receiving, by a runway traction estimation and reporting processor, a first sensor input indicating a first triggering event;
• starting, by the runway traction estimation and reporting processor and in response to the receiving of the first sensor input, a polling timer;
• receiving, by the runway traction estimation and reporting processor, a second sensor input in response to the polling timer indicating that a first period comprising one of 1/20 to 3/20 of a second and 1/800 to 3/800 of a second has elapsed, wherein the second sensor input is received in response to each indicated passage of the first period of the polling timer;
• causing, by the runway traction estimation and reporting processor, the polling timer to run until a third sensor input indicating an ending event is received;
• and
• processing, by the runway traction estimation and reporting processor, the second sensor input comprising a brake pressure and a wheel speed measurement;
• and
• calculating, in response to the processing, a runway friction estimate comprising a runway map comprising runway friction data comprising the second sensor input and corresponding location data corresponding to the location of the aircraft at each indicated passage of the first period of the polling timer,
• whereby wheel slip at each location datum is determined;
• and
• sending, by the runway traction estimation and reporting processor, a message to an output device in response to the determining the wheel slip at each location datum wherein the message comprises the runway traction estimate.
