Notice how no other company has followed WN's model for rampers doing walkarounds. If you're the only one doing it, there's a reason why.
I am friends with a WN ramper... I get texts fairly frequently with a picture of what he saw on the walkaround not understanding what he's looking at and if it's a problem (yes he does bring it to the crew's attention- usually they blow him off).
Letting non-pilots or mechanics inspect something that they don't really know how to inspect? Awful idea.
Sure, some guys just go through the motions, but the majority understand that they have skin in the game.
