experience doesnt count because a copilot with 3000h or 200h on the bus do the same task
It's not about flying the airplane.
If it was about flying the airplane there wouldn't be pilots at all. It would be entirely computerized.
It's about what to do when the airplane isn't doing what it's supposed to be doing.
And for that, the companies, the insurance companies, and the paying public, want to have someone in front who has seen a few situations, has lived a little, and won't panic when something goes wrong.
