If you plan to cross the Atlantic ocean, you better choose a proper plane if you want to make it safely from one end to the other. The route spans across hundreds of kilometers of ice cold water, icebergs, rocky terrain over Greenland and in general not especially plenty of opportunities to go down if necessary. So what you want is something a) reliable (aka not a single piston engine) and b) fast and c) well equipped with modern avionics.
We are privileged to be flying the best performing and best equipped single engine plane out there: The Socata TBM 850 manufactured by Daher (France). The wild lady is fitted with a Pratt & Whitney Canada PT6A-66D engine, rated at 850 hp in flight (700 hp at take-off), accelerating up to 320knots (600km/h) up to FL 310 (31,000ft, 9.5km) with a range of roughly 3000km. It allows us to cross the Atlantic in less than 12 hours with 4 stops.
The TBM also offers enough space and comfort with its large and pressurized cabin (means we dont need to wear ogygen masks) and seats for six. It also offers enough space for our equipment which is required if crossing the open sea (survival suit, raft, de-icing equipment).
Chances are high to face some rough weather on the way. Especially icing can become a significant danger to planes (also airliners btw). The TBM has anti-icing equipment which allows us to fly in certain icing conditions – which might be helpful as we are crossing Iceland, Greenland and the very North of Canada.
