When should turns at low altitudes above villages be avoided to minimize noise?

  • A

    During descent.

  • B

    During climb.

  • C

    During approach.

  • D

    In horizontal flight.

Refer to figures.
According to ICAO Doc 8168, Appendix to Chapter 3, related to "NOISE ABATEMENT DEPARTURE CLIMB GUIDANCE", is prescribed that

1. General

1.1 Aeroplane operating procedures for the take-off climb shall ensure that the necessary safety of flight operations is maintained while minimizing exposure to noise on the ground. The following two examples of operating procedures for the climb have been developed as guidance and are considered safe when the criteria in 3.2 are satisfied.

  • The first procedure (NADP 1) is intended to provide noise reduction for noise-sensitive areas in close proximity to the departure end of the runway (see Figure I-7-3-App-1)
  • The second procedure (NADP 2) provides noise reduction to areas more distant from the runway end (see Figure I-7-3-App-2).

NOTE:

Further information on Noise Abatement Procedures can be found in the attached figures.
