Aircraft noise
Land located close to airports and flight paths may be subject to aircraft noise. This noise is classified in 3 ways:
- mechanical noise — rotation of the engine parts, most noticeable when fan blades reach supersonic speeds
- aerodynamic noise — from the airflow around the surfaces of the aircraft, especially when flying low at high speeds
- noise from aircraft systems — cockpit and cabin pressurization and conditioning systems, and Auxiliary Power units
The Aviation Policy Framework outlines planning considerations with regards to aircraft noise
