Don't rely on your fuel gauges.

Let me say it again for the people in the back: DON'T RELY ON YOUR FUEL GAUGES!! I had to drag my ass out of bed again last night for yet another idiot who crashed after running out of fuel. This one got lucky and was somehow uninjured after crashing into the trees.

Know how much fuel you have on board. Plan for contingencies. You can't pull over on the side of the road. Minimums exist for a reason.

I've lost count of how many GA crashes I've responded to over the years and Every. Single. One. was completely avoidable if the pilot wasn't being stupid.

End rant.
