Bombardier Dash 8 Q400 is one of the quietest turboprop aircraft in the world developed by Bombardier Aerospace De Havilland Canada. The development of this aircraft is intended to meet the requirements of regional airlines for larger aircraft on high density routes and short distances. Q400 is the largest member of the Dash 8 family that can accommodate up to 80 passengers.
The Q400 program was launched in 1995 as a broad version of the Q300 series. The first flight of the Q400 aircraft was carried out in 1998 and entered commercial service in February 2000. The aircraft was equipped with a noise and vibration suppression (NVS) system introduced in the Dash 8 turboprop family in 1996.
The latest variant of the Q400 aircraft, the Q400 NextGen, was announced in March 2008. The new aircraft has improvements in the cabin environment, including LED lighting, new ceiling panels, sidewall windows and larger bins. Q400 NextGen participated in the 2012 FIDAE Air Show held in Santiago, Chile in April 2012.

The Q400 aircraft is powered by two PW150A turboprop engines supplied by Pratt & Whitney Canada. Each engine is capable of producing an output power of 5,071 shp or 3,800 kW. The engine is equipped with full digital engine control (FADEC). With the support of the PW150A engine, the Q400 is capable of flying with a maximum cruise speed of 650 km/ h with a maximum distance of 2,519 km.
