Well seeing that he is an Airdale, carrier time will come. As a former flightdeck yellowshirt, the best advice is.......Mouth shut, head on swivel. The lines painted on the flight deck are there for a reason. Walking behind aircraft is ok, but there is a certain way to do it. If a man or woman in a yellow shirt tell you to do something, it's best to listen. KEEP YOUR TOOLS OFF THE DECK!!!
Show up for FOD walkdowns...PLEASE!! And remember, no flightdeck crew (V-1) cares about your wing spread.
Anyway, the flight deck is an AMAZING place to be. Just tell him to listen, and always watch!
All this was done in humor, but so very true!!!
