This project has three main objectives. The first objective isto model noise from complete aerobatic routines for a range of aircraft. The second isto compare modeledand previously measured aircraft noise from complete aerobatic routines for a range of aircraft. The third isto model the noise from up to 50 daily aerobatic routines for a range of aircraft. The end result ofthis analysis isa matrix of modeled noise results for a range of aircraft performing a variety of aerobatic routines. The FAA can now utilize these results to help set the technical threshold for approving NEPA analyses for aircraft performing aerobatic routine represented within the matrix.
