OK, where is “specific operations” defined? Not disagreeing, but in a quick search I don’t see the term defined in 121 or 14 CFR 1. Would Night IFR over water be a specific operation?

We can play rule poker all day long, but those that work for the FAA have a little more pull. I have not dug into any of the policies, orders or Memo's (which may set policy) that the FAA has that defines the rules (law). Nor have I looked at any of the AC's that provide guidance to reaching the rule.
