A couple common ones working in very remote areas in Canada...
Salutation/Send-off: "keep your nose into wind and your tail out of the
bushes"
Philosophy of flight : 1) "Prepare for each flight like something is going to go terribly wrong. Then when you land you've had a good day!"
2) " You never want to come off a flight and kiss the ground....it usually means you were kissing your ass goodbye...FLY THE AIRCRAFT!"
Customer Relations: " If you answer the customers statement of requirements with a question it probably means you shouldn't be doing it!" ie You want me to lift THAT? or Excuse me?
On PDM and WX (VFR) : "If you 'think' you can see, I 'think' you could die. If you can't see, you should have known better and what I think doesn't matter. " A Chief Pilot.
