Fuel Capacity for a Transatlantic Trip
One day we want to fly our Sling TSI from the US to Europe (and back). This will require careful planning, good weather, survival gear, extra fuel, and nerves of steel. Flying to Europe is possible following a northerly route via Canada, Greenland, Iceland, and Scotland ( route ). The longest leg of this route is 676 nautical miles between Goose Bay (CYYR) and Narsarsuaq (BGBW). Routes with shorter legs are also possible, but those require more refueling stops ( example ). It seems reasonable to plan for a 700nm range with an additional 200nm to divert. After doing the math using the Sling's POH numbers, we worked out that we need 18g of extra fuel to get to a 900nm range (btw this will leave only about 100lbs for luggage). Note that our plane does not have the extended range fuel tanks installed. We decided against this, because it adds weight and complexity, and we can always add a fuel bladder on the back seat for those few times that we need it. TurtlePac makes fuel bladder
