The underlying theme on all these sorts of questions is that they are looking for a socially functional individual who can navigate grey areas while interacting with others, but at the same time will not compromise safety.
These are the guys they don't want...
- The spineless ipod wearing FO who's just along for the ride and is too weak to stand up to a CA in the interest of safety (or just doesn't give a rat's patootie).
- The inflexible rule nazi who thinks every FAR and GOM paragraph is to be taken verbatim and even trivial non-compliance reported immediately to the CP and POI. This guy LOVES to throw people under the bus, and none of the interview captains want to risk having to fly with him. He makes a crappy FO, but when he upgrades the real problems start...
The right answer in all these scenarios is to attempt to:
A) Intervene in a manner that gives the offender an opportunity to correct his problem with minimal personal repurcusions.
B) If that doesn't work stop the safety violation by any reasonable means, assuming the safety violation is significant (ie don't abort the takeoff on the roll because the CA refuses to put on his shoulder harness
)
