| 摘要 |
This invention relates to a computer network for calculating the true aircraft cornering friction coefficient of an aircraft runway or taxiway using the data collected by and available in the aircraft Flight Data Recorder (FDR) or other flight data management system, for example, the Quick Access Recorder (QAR). The invention may optionally distribute to personnel in the ground operations of an airport and airline operations, including but not limited to aircraft pilots, airline operation officers and airline managers as well as airport operators, managers and maintenance crews, the most accurate and most recent information concerning the true aircraft cornering friction coefficient to aid in making better and more accurate safety and economical decisions. |

1. A computer network for calculating and distributing a true aircraft cornering friction coefficient of an aircraft runway or aircraft taxiway, comprising:
(A) A computer for obtaining aircraft property data directly or indirectly from a flight data management system of an aircraft, wherein the aircraft property data comprises data pertaining to one or more of the following aircraft properties measured at various times for the aircraft and recorded on the aircraft's flight data management system: 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) Wherein the computer obtains at least some of the aircraft property data directly or indirectly from the aircraft's flight data management system; and (C) Wherein the computer calculates the true aircraft cornering friction coefficient of the aircraft runway or aircraft taxiway using at least some of the aircraft property data. |
