The one that always amused me years ago on the NOTAMS was "Pilots ECL" - I hadnt a clue what this meant so asked the Ops guy at the Indian airport we were departing from - "Oh that means Pilots to exercise caution on landing" - "Thats funny" I said "we always do that!"
Seriously though I think the situation with NOTAMS is quite appalling - we have to wade through all sorts of tripe and somewhere buried in there is something like "Airport Closed" etc. Its all a question of the airports covering themselves I think - they can say, well we told the pilots because its in the Notams.
We live in a world now where we are swamped with information but starving for wisdom!
