We'll start at Salzburg and hit most of the big runways in the Alps, all the way to Geneva, with a detour through northern Italy. Stops are at Innsbruck, Bolzano, Samedan, Bergamo, Milan (Malpensa) and Turin. There are going to be a lot of ups and downs on this one!
Although the plan was designed with large four-engined props in mind, it will work well for a variety of aircraft. Target cruise speed is around 220kts, ideally with decent altitude (up to 15,000ft) and climb performance. Good choices could include the Connie, DC-6, King Air, PC-12, Q400, or any private jet.
