A low pass...is a procedure that very few professional pilots are trained to do.
Sure, I'm confident to do one in a Cessna 172.
Sure, I'm pretty confident I can do one in an Airbus.
But flying an airliner is a highly proceduralized activity. What I am not comnfident about is to depart from my rigid procedures to improvise a low pass in a highly complex machine. I'm pretty sure I'll get it right, but that is not good enough.
But hey, maybe they practice low passes in the sim every six months in Argentina, what do I know!
