Here we go again.
How on Earth can an Aircraft be designed to be preflighted by a Pilot, instead of an Engineer?
PLEASE EXPLAIN.
You may as well say that these Aircraft are designed to be flown normally on autopilot, usually three of them, so why do we need two other Pilots as well.
Don't tell me, I KNOW what you are going to say.........
The two Pilots are there in case something goes wrong, and one or both of them might have to actually fly the Aircraft, right.
Oddly enough, I always thought that was ONE of the many reasons that the LAMEs were there, just in case.
