Microphones concealed throughout the cabin transmit noise information to a special on-board computer that also receives propeller speed. The computer continually analyzes this information and signals devices on the fuselage frames to produce out-of-phase vibrations to counter the original vibrations. Both the 70-seat “A” and 72 to 78-seat “B” versions feature a spacious, contemporary interior design. The pressurized cabin contains wide-body two-by-two seating, standup headroom and easy access to the ample overhead bins on both sides of the centre aisle.

Built with an ideal blend of advanced technology and low complexity, it is the new standard in terms of reliability, durability, and operating economics. The PW150A was certified on June 24,1998 just 36 months after the program was officially launched. The PW150A produces up to 5071shp for takeoff or nearly double what older technology engines produce and yet it has the fuel consumption values of turbo-prop engines nearly half its power. Operating economics are superior to similar-sized jet engines. The PW150A features advanced materials and cooling technology which leads to long engine life and lower maintenance costs. It has Full Authority Digital Electronic Control (FADEC) which provides ease of operation, precise control, and reduced maintenance costs. The engine also features an Engine Monitoring System or EMS which provides engine trend monitoring and data recording to simplify the task of fault detection and troubleshooting.

The 13.5 ft/4.11m diameter propellers are designed to turn slower than those on other Q Series aircraft, reducing community noise levels. The propellers feature a digital electronic control system which accurately sets propeller blade angle and RPM, as well as facilitating the “synchrophasing” of the propellers to reduce cabin noise levels. The shape of the propeller has also been refined to be much closer to the aerodynamic ideal with thinner blades and a considerable amount of sweep introduced towards the tips.

The HGS projects terrain and flight display information in the pilot field of vision. This facilitates flying the aircraft in low visibility conditions. It also improves the pilot situational awareness, and hence operational safety, by allowing the pilot to look out of the windscreen rather than down at the instruments. The HGS system also allows the pilot to achieve stringent and very precise Category IIIa landings.
