I wear it as it’s purely my comfort zone. Prior to Aviation I was in another industry for 15 years, that was a uniform also, strict uniform procedure I must say. I have never worn casual to work in my life since I finished Year 12, in or previous to my flying career. It would probably be a distraction if I wore casual if I did , which is why I don’t, sim time is hardly time for that.
I dont wear wear the tie, but that’s barely worn on the line at all these days by many.
All the young ones roll up in ripped jeans etc.
