john_tullamarine, Then I would suggest certain parts of the study be impressive for the greens. If the software does what J. Purry indicates, it could be used to demonstrate how derate takeoffs and aircraft not maintained as well as others offend the airport communities noise wise much more often. If one can corelate noise monitor data with a specific takeoff you could demonstrate why airlines that choose to operate using derate or not maintain their airplanes as well should/could pay more noise related fees.
Noise certification for takeoff is done with AC off, mid cg and MAX thrust. It also uses a cutback procedure that would unsettle most passengers. How many airlines you know of operate in this configuration? Thats right, zero for the most part. I guess that means that the QC system is based on bogus noise numbers that are not achievable in normal operations.
Kinda off topic, but the first post grabbed my attention along these lines.
