The Bulletin also reports on non‐acoustical influencers that play into an individual ’ s perception of whether a noise is tolerable . For example after September 11th , it was reported in surveys by persons hearing military aircraft or emergency rescue helicopters that they felt safe and secure with hearing that noise . Conversely , persons reported being annoyed by civilian / commercial aircraft noise , especially if in the past the person had complained and there was no acknowledgement by the airport operator that there was an issue .
Ultimately , the Bulletin indicated that the data and modeling programs are not well developed for predicting annoyances associated with noise generated by military aircraft in low‐level flight corridors .
Findings
• Noise modeling data is not well developed for MTRs and special use airspaces between Seymour Johnson AFB and the DCR .
• There are no formal coordination procedures and limited communication with the communities impacted by the low‐level MTRs .
• The DOD undergoes a comprehensive environmental assessment to comply with NEPA requirements during any proposed new missions or mission changes ; however , the NEPA assessment does not evaluate noise generated by low‐level flight operations in the MTRs and Restricted Areas .
ISSUE NOI‐5
Compliance with Minimum Military Airspace Concern that aircraft fly belo in Military Training Routes an intensifies noise in communit
Compatibility Assessment There is a concern that operators of military air with the minimum floor altitudes in MTRs and R from 500 ft . AGL over sparsely settled areas and Areas .
These minimum flight altitudes and activation t are published by DOD and require pilot complia depending on the angle and trajectory of the ai any visual references , the public may not be ab actual altitude of an aircraft in flight .
