Boeing 787-9 in-flight exhaust emission analysis for the selected flight

Measurements of emissions of harmful compounds in the exhaust gas of jet engines are carried out using stationary engine tests. These tests only determine the emission of harmful compounds in the near-airport operations. This creates the need to develop methods and tools that would allow to estimate the emission values of harmful compounds during all operations carried out by the aircraft, including when flying at a given flight level. In order to develop such a method, data from the on-board flight data recorder were associated with the emission factors determined during the LTO test, which is the basic certification test of aircraft engines. The following article presents the methodology necessary to estimate the real emission of harmful compounds during the flight of a Boeing 787-9 Dreamliner, equipped with Rolls-Royce Trent 1000-G engines.
