Sounds like a terrific adventure MDinana,
I agree with Ironraven on the headlamp, I use mine more often now than my hand-held light.
It is important to carry some survival gear on your person when flying as you may have to escape from a rapidly sinking or burning aircraft. On the main "Doug Ritter ETS" site there is lots of information on what to carry on-your-person and in your pack on a light aircraft. Very good information.
I often fly in contract or government-owned light aircraft and always carry a mini-PSK kit with me even though I know there is a good kit on the plane.
There are minimum kits required by law when flying remotely in Alaska, Doug Ritter listed it
here .
Good luck and be sure to post some pictures when you get back!
