North Atlantic Ferry
I have made a couple of these trips, as posted earlier, weather is everything. You must also be very proficient in NDB procedures, these are the only approaches available along your route. HF radio is no longer required, Sat phone is acceptable and a whole lot better. They are now much more affordable to rent for the trip. You will need a Immersion suit, survival gear, life raft, etc. The Canadian CAA used to have a mandatory inspection prior to departing, they looked at the airplane, your flight planning, reserves, equipment, etc. This is no longer mandatory but they do spot checks on occasion. Insurance is the show stopper for most people, I doubt that you will find a company to cover you on a solo crossing for the first time. The stats are 1 in 200 don't make it and a lot of those were experienced, high time pilots. When you get to Greenland the walls of the Ops shack is plastered with crashed airplanes, but most are never found. Your destination in Europe or wherever your final is will determine whether you take the Most Northern, Middle, or Southern route. The Northern route is for those aircraft with the least amount of range. Check your PM, I could rant forever on this. Good Luck!
