Avro RJ70

The Avro RJ70, introduced in the mid‑1990s, is the smallest member of the Avro RJ family, derived from the BAe 146 series. Developed under the auspices of the de Havilland Aircraft Company after its integration into the British Aerospace group, the RJ70 retained the high‑wing, four‑engine layout while adding a modern cockpit and improved fuel efficiency. Its 20‑seat cabin, quiet operation and short take‑off and landing capability made it ideal for thin routes and airports with restrictive runway lengths. Powered by two Rolls‑Royce RB.183 turbofans, the jet could cruise at Mach 0.65 and met strict noise‑abatement regulations. The avionics suite featured an integrated flight‑management system and FADEC, reducing pilot workload and maintenance costs. Operators such as KLM Cityhopper, Swissair Regional and the Royal Air Force auxiliary squadron used the RJ70 for both civilian and training missions, demonstrating its versatility. Although produced in modest numbers, the aircraft proved that four‑engine regional jets could compete with twin‑engine designs, influencing later regional airliner development and reinforcing de Havilland’s reputation for innovative, adaptable aircraft. Today a few RJ70s remain in service with niche operators, serving as a testament to the design’s durability and its role in expanding regional connectivity across remote airfields.
