Patent ID: 8682561

Claim:
A computer network for calculating and distributing a true aircraft braking friction coefficient for an aircraft runway or taxiway comprising: (A) An aircraft having a flight data management system for recording one or more sets of data points thereon, wherein the one or more sets of data points pertain to one or more of the following aircraft properties measured at various times for the aircraft: aircraft ground speed, aircraft brake pressure, aircraft longitudinal acceleration, aircraft engine thrust setting, aircraft reverse thrust setting, aircraft engine revolutions per minute, aircraft air speed, aircraft vertical acceleration, aircraft spoiler setting, aircraft airbrake setting, aircraft aileron setting, aircraft flap configuration, aircraft pitch, and aircraft autobrake setting; (B) A computer which obtains the one or more sets of data points pertaining to the one or more aircraft properties; and (C) Wherein the computer calculates the true aircraft braking friction coefficient of the aircraft runway or taxiway using at least one of the one or more sets of the data points pertaining to the one or more aircraft properties obtained by the computer.
