Avro Twin Sun 1000: rise to greatness

Twin Sun: if one is good, two is better

Twin Sun: Rise above the others, about 15 thousand feet to be exact

Twin Sun: your twin has a VNE speed, ours has a critical mach number. We are not the same

In the late 1970s, Avro sought to increase revenue and gain a foothold in the thriving general aviation market. Specifically, they wanted to go after the well heeled, aspirational pilots who were in the market for a higher performance piston plane that could carry a growing family and a substantial payload, while being both faster then comparable single engine options and substantially cheaper than turboprop or jet powered aircraft. For long distance travel, flying above most weather is only comfortable with pressurization, which they obliged by using the powerful turbocharging system of the Rolls Royce Red-Tail, the most powerful piston engine on the market, with over 500 brake horsepower, giving a maximum speed of over 400 mph and a cruise of 330 at 70% throttle, over 80mph faster than fast cruising twins such as the Cessna Golden Eagle or Aerostar 600. With seating for up to 6, a large payload capacity and front and rear cargo bays with flat floors were engineered into the design, enabling easy CG calculations. In order to provide enhanced safety in engine out scenarios, an anti spin parachute was fitted as standard equipment, enabling recovery from flat, inverted, and developing spins. Pneumatic de-icing boots and electric prop de-icing enable safe operations in all weathers.
