I think that 'Airduel' was the US release name. It is called 'Dogfight: 80 Years of Aerial Warfare' originally and it was by Microprose UK. A very fun sim which allowed you to fly up to 2 aircraft from 6 eras, namely the Sopwith Camel and Fokker Triplane in WW1, the Spit and Bf 109 in WW2, F-86 and MiG-15 in Korea, F-4 and MiG-21 in Vietnam, Sea Harrier and Mirage in the Falklands, and F-16 and MiG-23 in Lebanon.
