AFE now actually sell 5 bars.
Bars are in my view are aload of crap on the light aircraft scene.
If your working at a flying school and need to rely on bars to stamp your authority on the punters your in the wrong game.
As for turning up at a strange airfield with a student in the LHS I have never yet been confused with a pax. If you look confident and carry yourself shoulders back and look the part everyone presumes your the PIC what ever your wearing. I have even tried to sneak off when the security gimp was waiting to moan at something in causal dress thet fecker always walks up to me.
