On April 19, 1983, the de Havilland DHC-8 rolled out and obtained over 3,800 hours of test for more than two years during the series of PW100 engine tests. On June 20, 1983, the aircraft took to the skies for the first time. On December 16, 1983, the PW120 engine received its certification. The Dash 8 is a development of the Dash 7 which is equipped with better cruising performance and lesser operating cost, however, without short takeoff and landing characteristics.

The DHC-8-200 has a similar thirty-seven to thirty-nine passenger with the Series 100, however, it was fitted with more powerful engines to boost its performance. The aircraft is powered by two Pratt & Whitney Canada PW123 turboprop engines which produces a maximum thrust of 2,150 shaft horsepower. The engine has two-spool, two-stage centrifugal compressors, reverse-flow combustors, single-stage low-pressure and high-pressure turbines, and two-stage power turbine, and self-contained oil system.

The Series 200 has a high cruise speed of 289 knots and a range of 1,125 nautical miles. It has a service ceiling of 25,000 feet and a rate of climb of 1,475 feet per minute. The takeoff distance is 1,000 meters while the landing distance is 780 meters.

The de Havilland Series 200 has a maximum takeoff and landing weight of 16,466 kg and 15,649 kg, respectively. It has a maximum payload of 4,647 kg, an operating empty weight of 10,477 kg, and a fuel capacity of 835 US gallons. The aircraft has an exterior length of 22.25 meters, an exterior height of 3.2 meters, a tail height of 7.5 meters, and a fuselage diameter of 2.69 meters.

Determining designs of the DHC-8 include the enlarged T-tail configuration aimed to save the tail from prop wash while taking off, a wing aspect ratio of around 12.32 to 13.36 which is considered very high, stretched engine nacelles that hold the undercarriage, as well as a sharp and conical nose. It has a wingspan of 25.89 meters, a wing area of 54.40 square meters, and a wheelbase of 7.8 meters.
