Oh dear, someones upset the mighty IO540.
An AOC requirement (in EASA land) is that approach plates for any country that AOC may fly to are checked against the relevant Air Pilot. Most line pilots will not even know that such an action is carried out as they have no requirement to know, in a major carrier the Air Pilots are held in OPs Admin and the checking takes place there. Surely IO540 would have known that as he so often spouts off at others quoting his great knowlwdge and expertise.
JEPP/AERAD become the defining documents for AOC pilots by the virtue of the fact that the Ops Manual will state which type of plate is to be used, and therefore JEPP/AERAD actually become part of the Ops Manual, and the limits defined there become company limits, unless there is an AFM limit, or performance limit which calls for a higher limit to be imposed.
