This appears to be an inconsistency with the frequent citation of too low and too loud aircraft, the principal sources of Lmax noise levels that cause these disruptions. 8-1 119 C H A P T E R 8 Noise Abatement (Airside)

The recently published document "Aircraft Noise Effects" (145) describes in some detail the volume of literature and current understanding associated with the disruption of several different types of activity associated with aircraft noise events.

On approach or departure, use of specific departure headings, waypoints, and FMS/GPS procedures can be very helpful in keeping aircraft over the designated flight path. Flight track modification has been used to define preferred departure routes and approach courses, to separate large and small aircraft for noise abatement and to increase operational efficiency, and to specify courses for general aviation propeller aircraft and helicopters to assure that they do not conflict with faster jet aircraft.

Take Off Thrust and Flap Management Procedures Purpose: This strategy utilizes specifically designed departure climb procedures to minimize noise impacts over communities. The FAA has issued Advisory Circular 91-53A, Noise Abatement Departure Profile, which specifically outlines power setting and flap management techniques for aircraft to minimize noise for communities located either "close-in" to, or "distant" from, the airport.

Displaced Threshold - Landings Purpose: A landing threshold may be located farther from the overflight end of the runway than the normal touchdown zone to seek noise abatement. This action may be implemented 8-7 126 Aircraft Noise: A Toolkit for Managing Community Expectations

Arriving aircraft would land at or after passing the displaced landing threshold. Displaced thresholds are more often used for obstacle clearance than noise abatement because their effectiveness in reducing noise is so small.

Best Practices Based upon the effectiveness and ease of implementation associated with the various noise abatement measures, as well as the results of surveys and interviews conducted for this analysis, several techniques may be identified as best practices for achieving the greatest reduction of noise for the least cost and effort. These are: Flight Track Modification In areas of varied land use, the development of preferred flight paths over areas of compatibly used (generally non-residential)
