This will also come into play with the airstrip now under construction on St Helena in the South Atlantic, where the key operation envisaged seems to be an A319 from Cape Town. (1,700 nm). The runway length of 1,550m looks decidedly miserly for such an operation. It's not apparent whether fuel will even be available there or whether round-trip fuel is compulsory.
I wonder how the Cessna 337s got to Easter Island.
