"Part 121 pilots are required to be airport qualified for every Regular, Provisional, and Refueling airport set forth in their ops specs"
Not sure whose quote this, (aterpster perhaps) but could you please provide a reference to the requirement?
If indeed it says something to that effect, then I question the way it's being interpreted. Sure, there are special airports that require a checkout, there's airports that have special approaches, there's airports that I'm required to review the pictorials for, but to say every airport requires me to be qualified has me scratching me arse a bit. If to say I review 10-7 charts, study in depth the expected STAR and approach, airport diagram and ramp set up along with anything else I can get my hands on qualifies as a qualification, then we agree. If to say the first time I went to Des Moines I had a LCA riding shotgun, then we disagree.
