What is typically restricted during designated hours under Noise Abatement procedures?

During designated hours under Noise Abatement procedures, training flights are typically restricted. This is primarily because training flights often involve maneuvers that can generate higher noise levels, such as takeoffs, landings, and circuits. These movements can be more frequent and less predictable compared to other types of operations, leading to increased noise impact on surrounding communities.

By limiting training flights during specific hours, airports aim to minimize disturbances in residential areas and maintain good relations with the community. Other categories of flights, such as cargo flights, general aviation, and private jets, may not be subjected to the same level of restrictions during these sensitive periods, depending on the specific noise abatement policies of the airport. This targeted approach helps focus efforts where noise reduction is most critical, ensuring that operations can continue while still respecting the needs of nearby residents.
