RE: proper ID
1) Yes, I know its in the rulebook.
2) Yes, I know its "checked" at the NATS.
My question could have been stated "What is the purpose of the rule?". Other than the joy some guys get from having another rule to follow, Grotto2's explanation is the best (and only) explanation of a reason behind the rule. Hopefully contests will some day get big enough to where there will be "line workers", so for now I'll just assume that it's a holdover from the days of 100+ pilot contests. ..
I still haven't seen what the consequences are for not having that number on the airplane. . . has anyone had a flight Zero'ed for this? I mean, without speeding tickets, speed limit signs are just a big waste of money. . .
