RFM Noise Levels
According to the FM, 175 noise levels have been determined under conditions prescribed in Chapter 8 and Appendix 4 of Annex 16 of ICAO, volume 1 etc etc
Understand using Chapter 8 methods but why Appendix 4?
Appendix 4 is for helicopters NOT EXCEEDING 3175 kg Max Certified TOW.
Or is it a case that they meant to refer to Appendix 2?
