> You have a main and a backup pilot, but either one must be 100% capable of doing it on their own. The backup is silently double checking, but their assignments are more about ensuring that the copilot doesn't just check out because they're human.

Pilots also generally take turns who is manipulating the flight controls (“flying the airplane”) each flight.
