DE HAVILLAND CANADA DASH 8-400 MEETS ICAO’S NOISE STANDARDS
De Havilland Canada Dash 8-400 Turboprop becomes first regional aircraft re-certified to meet ICAO’s most stringent Chapter 14 noise standards.
On 1 September, De Havilland Aircraft of Canada Limited announced that the Dash 8-400 turboprop aircraft has been re-certified to meet the latest noise emission standards set by ICAO Chapter 14. The Dash 8-400 aircraft is the first propeller-driven aircraft and also the first regional aircraft in the world, to achieve the certification. ICAO Chapter 14, which is equivalent to FAA Stage 5 and is the most recent in a series of stringent noise limits introduced by governing bodies to regulate aircraft noise emission, takes effect after 31 December 2020 for all new subsonic jet and propeller-driven aircraft.
Featuring quiet, swept, six-bladed Dowty propellers on Pratt & Whitney Canada PW150A engines, the Dash 8-400 aircraft has once again proved to be an environmentally advanced design. Not only is it quiet on the outside, it is also quiet inside the cabin. In order to further boost the comfort for passengers, the Dash 8-400 aircraft is engineered with a newly improved, proprietary Active Noise and Vibration Suppression (ANVS) system that effectively reduces the propeller noise level inside the aircraft to maximize cabin comfort. The Dash 8-400 aircraft has been acoustically engineered to mitigate the detrimental effects of noise on human health: inside and out, on the ground and in the sky.
With its acquisition of the Dash 8 aircraft programme,Longview Aviation Capital has proudly relaunched De Havilland Canada, one of Canada’s most iconic brands. De Havilland Canada’s portfolio includes support to the worldwide fleet of Dash 8-100/200/300/400 aircraft, as well as production and sales of the Dash 8-400 aircraft. With its low carbon footprint and operating costs, industry-leading passenger experience and jet-like performance, the Dash 8-400 aircraft, which seats up to 90 passengers, is the environmentally responsible choice for operators seeking optimal performance on regional routes.
