The FAA publishes Information for Operators documents giving:
valuable information for operators that should help them meet certain administrative, regulatory, or operational requirements with relatively low urgency or impact on safety.
Some of these documents seem to offer interpretations on regulatory matters, and are sometimes cited as such. In some cases, these interpretations may provide permission to operate more freely. However, I could imagine that in the case of others, the interpretations may prove to be more restrictive and burdensome than a plain reading of the regulations.
What regulatory or legal weight do do these InFO publications carry, if any? Since these notices are directed at certified operators, does the answer vary depending on the audience?
