Yep, when our perfidious class was in RAF training we remembered it "Right begins with an 'R' and Red begins with an 'R' - Red's on the Left"
By the way I think TCAS on ships is a good idea - as in "descend - descend now..."
Finally one for DADA - apparently the word Posh comes from Port Out Starboard Home - the "posh" guys booked the coolest side of the ship to the Far East and back. These days I guess they book the sunny side for a cruise.
