aviation management is weird in that way
you want to do everything the safest way possible, but you dont want to deviate from the standard.
as far as handling pressure goes, a bug part of aviation is understanding what pressure is and where it comes from. in a healthy organization pressure doesn’t exist, because all you have to do is your job, and the only pressure comes from yourself, but you have everything you need so there is no pressure.
when things go wrong it is almost always more luck than skill that saves the day.
air France 447 had not one, not two, but three pilots in the cockpit, I can’t remember the exact number but there was definitely combined experience of over 10k hours and they managed to make a mistake you learn how to avoid in lesson three.
if people meet the standard there is no objective difference between them because you can’t move the standard. you cant change the limits and when shit goes wrong its pretty much over before it starts.
when you interview and hire a pilot the rest of it is sorted out by the standards and your training, if they make it through they’re good to go.
