Did you miss the part where the question applies to 121 US certificated pilots? Are you that? If not then STFU.
This was a bad idea. Thought I'd get a few people to cast their opinions, instead I get retards telling me they aren't a 121 pilot and others offering where I can look up regulation. sheesh...
To those that actually met the prerequisites of the worlds most simple question (US certificated pilot flying for a 121 carrier) thank you.
To those that responded without the qualifications to answer or with a suggestion where I can find something any pilot can find...thank you. Your efforts are appreciated...really.
