AIR32
INTRODUCTION This report is intended to encourage more effort to be directed toWard improving the pilot's visibility from the cockpit of transport type aircraft wih the ultimate objective of improving safety. In the preparation of this Aeronautical Information Report, consideration Was given to pilot surveys made by the Civil Aeronautics Administration, studies made by manufacturers, and a review of the cockpit visibility provided in present day transport aircraf`t. It is recognized that a rigid specification is undesirable and may restrict development and utilization of initiative. For this reason the report is in general terms and offered as a guide.

It is the purpose of this aerospace Information report to provide a listing of existing and forthcoming metric standards for aerospace fluid systems. It is shown which ISO/TC 20 and ISO/TC 131 or other ISO Technical Committee documents have been approved by the United States Technical Advisory Group (U.S. TAG) to TC 20. This AIR also lists U.S. Aerospace accepted AECMA and international De-Facto standards, also the forthcoming standards being developed in ISO/TC 20/SC 10.

Helicopter External Noise Estimation

2012-08-16
CURRENT
AIR1989B
This method estimates noise for both single and tandem main rotor helicopters except for approach where it applies to single rotor designs only. It does not apply to coaxial rotor designs. Due to lack of available data, application of the method has not been evaluated for application to tiltrotor, or other VTOL configurations, when operating in the helicopter mode. Since there are substantial differences between helicopter rotors included in the data base, and tiltrotor rotors, application to VTOL configurations other than helicopters is not advised. Application is limited to helicopters powered by turboshaft engines and does not apply to helicopters powered by reciprocating engine, tip jets or other types of power plants. It provides noise information using basic operating and geometric information available in the open literature. To keep the method simple, it generates A-weighted sound levels, and Sound Exposure Levels precluding the necessity for spectral details.

This method estimates noise for both single and tandem main rotor helicopters except for approach where it applies to single rotor designs only. It does not apply to coaxial rotor designs. Application is limited to helicopters powered by turbo-shaft engines and does not apply to helicopters powered by reciprocating engine, tip jets or other types of power plants. It provides noise information using basic operating and geometric information available in the open literature. To keep the method simple, it generates A-weighted sound levels, precluding the necessity for spectral details. The method prescribes estimates for typical helicopter operations; certain maneuvers may produce noise levels different from those estimated. Estimates are given for the maximum sound levels at 4 ft (1.2 m) height above the ground. For aircraft in forward flight, the estimate is given for an aircraft at an altitude of 500 ft (152 m) on a path directly over the observer.
