The thread drew my attention as I would like to attempt the Atlantic Crossing one day (perhaps to fly into Oshkosh). Timothy, I'd go via Iqaluit as well with a thumping great ferry tank in the C182, though my routing would be Wick, Reykjavik (BIRK), Kulusuk, SondreStrom, Iqaluit and then down through Canada. Having worked in Greenland and seen the spectacularly rapid weather changes, my criteria would be that I would like to have enough fuel to go back to where I came from or even further back if the fog rolled in (I'm a project manager not an adventurer). But that discussion is one for another forum.

My longest single flight not passing a single airport was 1385nm, though it has to be said that the GC coincided with the rhumb on that one
