To test different types of noise abatement approach procedures the Institute of Flight Guidance and the Institute of Aerodynamics and Flow Technology performed flight tests on the 6th September 2010 with a Boeing 737-700. In total 13 approaches to the Research Airport in Brunswick were flown while the approach area of the airport was equipped with six noise measurement microphones. Brunswick airport is equipped with an experimental ground based augmentation system (GBAS) which allows the implementation of 48 ILS lookalike precision approach procedures with different approach angles simultaneously
