Flight data monitoring and validation
First Claim
1. A computer-implemented flight data monitoring method comprising:
- receiving input flight data captured by an on-board recorder of an aircraft;
performing flight data validation on the input flight data to generate validated flight data; and
performing flight data analysis on the validated flight data to detect at least one predetermined type of flight event;
wherein the input flight data comprises a set of parameters sampled at time intervals providing a series of data values for each parameter; and
the flight data validation comprises a repeating pattern test for detecting occurrences of a repeating signal pattern in data values of a parameter of the input flight data based on a comparison of a first set of data values of said parameter of the input flight data with a subsequent set of data values of said parameter of the input flight data.

Abstract
A computer-implemented flight data monitoring method is provided for monitoring flight data, for example flight data obtained by a flight data recorder or quick access recorder on an aircraft. The method comprises receiving input flight data, performing flight data validation on the input flight data to generate validated flight data, and performing flight data analysis on the validated flight data to detect at least one predetermined type of flight event. The events may be useful for generating an aircraft safety report, for example. By validating the data before performing the analysis, the number of events which are falsely detected based on invalid or unreliable data can be reduced.
