The appendix presents perceived noise level contours for the takeoff and landing operations of the following types of civil aircraft: (a) two and three engine, short and medium range turbojet and turbofan transports (b) multi-engine small business turbojet and turbofan aircraft (c) two-engine piston and turboprop aircraft, both transport and business. These contours permit the determination of the noise level in PNdB over a wide area beneath and off to the side of a flight path. The appendix also includes a runup noise contour for estimating the noise from ground runups of civil and military turbofan engines.
