Leper of the taxiway
Always been my habit to put the sun at my back TM, so the cockpit doesn't become a furnace. As for hangar doors, especially the open kind, I never go near 'em with a helo. I've had strips torn off me by hangar rats for having the audacity to hover taxy along the marked taxi way a good 10m from their open doorways.
PS You end up with weather radar or a stormscape in that 407? If so has it saved your scrawny neck yet?
