The Bombardier DH4 Aircraft is the Bombardier Q400 regional turboprop aircraft. The DH4 is marketed as the Q400 by Bombardier. The Q400 is sometimes called the DH4 because DH4 is the International Air Transport Association (IATA) code for the Bombardier Q400 airplane. The DH4 IATA code is used primarily by airlines to identify the aircraft. The DH4 code is commonly found in ticketing operations and in schedules of flights. You will see the code, sometimes, when booking a flight online. When you see DH4 it is referring to the Bombardier Q400 IATA code.
The Other Name for the Commercial Turboprop Aircraft
The DH4 may also be called the De Havilland DH4 aircraft because De Havilland was the previous division of Bombardier that developed the aircraft. Bombardier has phased the De Havilland name out, however many still use the De Havilland name. The Q400 also has many other names which you can read more about here on the site. This includes The DH8D Aircraft, which is the ICAO code for the aircraft. The aircraft is also sometimes called the De Havilland Dash-8-400, which was the original name of the turboprop or the Bombardier DHC-8-400, which is the official name of the airplane. A quick review of the airplane and a list of the other pages where you can read more about the turboprop is listed below the photo of the plane.

Background on the DH4 Turboprop Aircraft
The DH4, Q400, is a two engine regional turboprop airplane built by Bombardier Aerospace in Toronto, Canada. It is commonly known for its speed, quietness and larger size in the regional aircraft category. As a regional aircraft, it primarily flies on short routes under 1,000 miles. The De Havilland DH4 cruise speed is 360 knots and is powered by two Pratt & Whitney Canada PW150A engines that can produce up to 5,071 shaft horsepower (SHP). The aircraft was launched in 1995 by Bombardier and certified by Transport Canada on August 4th, 1999 and on January 26, 2000, by the Federal Aviation Administration (FAA). The DH4 aircraft typically seats 70-76 passengers in a two by two seat configuration, however, it can now seat up to 86. The new 86 seat configuration was launched by Bombardier in 2014 when Nok Air (Thailand) started flying the 86 seat version.
