DHC7

The DHC-7 (Dash 7) is a twin-engine turboprop airliner developed by de Havilland Canada, now part of Bombardier Aerospace. It was designed to serve short to medium-range routes, typically between 500 and 1,000 nautical miles. The aircraft first flew on May 12, 1975, and entered service in 1976. The DHC-7 is known for its reliability, efficiency, and spacious cabin, making it popular among regional airlines.

The DHC-7 features a high-wing configuration with a swept-back tailplane, which provides good stability and control. It is powered by two Pratt & Whitney Canada PT6A-67 turboprop engines, each driving a four-blade propeller. The aircraft has a maximum takeoff weight of approximately 33,000 pounds and can accommodate up to 78 passengers in a typical three-abreast configuration.

The DHC-7 has been used by numerous airlines worldwide, including regional carriers, cargo operators, and military organizations. It has also been used for various roles, such as passenger transport, air ambulance, and aerial survey. The aircraft has a proven track record for its durability and low operating costs, contributing to its enduring popularity in the regional aviation market.

In 2006, Bombardier Aerospace introduced the DHC-7 Dash 7Q400, a modernized version of the original DHC-7. The Dash 7Q400 features updated avionics, improved aerodynamics, and a more powerful engine, the Pratt & Whitney Canada PW150A. This variant offers enhanced performance, reduced fuel consumption, and increased passenger capacity, making it a popular choice for new operators and upgrades.
