Chuck, Its the stuffy Bitish respect for rules and regulations, you have seen how we like to stand in queues!
You know how a PPL could not possibly let mum or dad have a go at straight and level becuase he is incapable of seing if a mistake is going to be made unless he has:
a) done the ATPL exams
B) the FI rating
c) sat in the right seat of a 152 for 3000hrs while waiting for the jet job
and of course don't forget being a "frozen" airline pilot!
The brits do like to collect "badges"!!!!
