Calm down pruners...
Half of you are arguing for the validity of wearing a uniform, fair enough, it may have it's advantages in getting you in a professional mindset, it may not affect you at all.
The other half are saying that a uniform doesn't necessarily make you a better pilot.
You're essentially arguing different points, and if you were to ask the question "Do you believe that wearing a uniform has a direct and measurable effect on the performance of a pilot in training?", almost all of you would say either 'no' or 'depends on the individual'.
Likewise, if you were to ask "Do you understand why FTOs have a uniform?", I bet you would all give the same bloody answer!
Is there any issue you disagree on or are you arguing for different questions?
