Bulldog Series 100

The Scottish Aviation Bulldog Series 100 is a single‑engine, two‑seat trainer that entered service in the early 1970s. Developed from the earlier Bulldog 1 prototype, the Series 100 was built at the company's Glasgow facility between 1972 and 1977, with a total of 140 airframes delivered to the Royal Air Force, the Indian Air Force, and several civilian operators. Powered by a Lycoming O‑360‑A4A air‑cooled piston engine delivering 180 hp, the aircraft features a low‑wing cantilever design, all‑metal construction, and a fixed tricycle undercarriage that simplifies ground handling for student pilots. Its cockpit is equipped with dual tandem controls, blind‑flight instruments, and a basic avionics suite that can be upgraded to include modern VHF radios and GPS navigation. The Bulldog Series 100 proved indispensable for basic flight training, aerobatics, and liaison duties, offering forgiving handling characteristics and low operating costs. Its reliability and straightforward maintenance helped standardise pilot training across multiple air forces during the Cold War era, and it laid the groundwork for later variants such as the Series 200 and 300, cementing Scottish Aviation’s reputation as a capable military trainer manufacturer.
