Abstract

This invention relates to method and apparatus of the calculation of aircraft braking friction and other relating landing parameters including but not limited to aircraft braking action, aircraft takeoff distance, aircraft landing distance, runway surface conditions and runway surface friction based on 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) to provide every involved 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 on the true aircraft landing performance parameters to help better and more accurate safety and economical decision making.

Claims

1. A method of a calculation to determine real-time or by post processing the true aircraft braking friction coefficient based on the data collected by and available in the aircraft flight data management systems such as the Flight Data Recorder (FDR).

2. A method of a calculation to determine real-time or by post processing, based upon the method in claim 1, other relating parameters including but not limited to aircraft braking action, aircraft cornering friction coefficient, aircraft takeoff distance, aircraft landing distance, runway surface conditions and runway surface friction.

3. An apparatus onboard of the aircraft to give a real-time low braking action warning to help pilots to make critical decisions during landings and takeoffs based on the method in claim 1

4. An apparatus for calculating all the parameters in claim 1 and 2 onboard of the aircraft to help pilots to make critical decisions during landings and takeoffs based on the method in claim 1.
