Method of presenting flight data of an aircraft and a graphical user interface for use with the same

A method of manipulating flight data of a plurality of aircraft, comprising the steps of:

• a. receiving dataset associated with the aircraft from a data management system, wherein the data management system is arranged to store binary flight data associated with different airlines or different aircraft models in different formats, wherein the binary flight data is associated with flight parameters over a phase of flight;
• wherein step a includes step 1a of converting the binary flight data recorded by a local recording means of each of the plurality of aircrafts or different data sources into engineering flight data of a standard format or protocol;
• b. applying an analysis process to compare at least two portions of the received dataset associated with flight parameters over the phase of flight;
• and
• c. presenting the analyzed data portions to a user in a visualized manner;
• wherein step b includes using a clustering method to identify flights following predefined standard operating procedures and at least one anomalous flight represented by non-clustered data patterns identified by the analysis process.
