Well guys I think it astonishing that something as simple as bars on someones shoulder can arouse so much interest. Many people say that pilots in small aircraft should not wear a uniform or bars. This is rubbish. Any pilot who is being paid to fly and who is dealing with customers should wear a uniform and shoulder boards. Silver for GA instructors and charter pilots and gold for the airline industry. 4 for the pilot in command, 2 or 3 for the second in command.
If your flying aerobatics or workin the line or logging or whatever then wear whatever you like because no-one who is responsible for your income and who needs to feel secure in your skill is going to see you.
Personally I think the uniform should be secondly used as a tool for

picking up girls. That's just me. Any opinions? Has it worked for anyone?
