NOTAM: Notice to Air Men (non PC)

"Notice to Air Missions"

Notices of Temporary changes in procedures at an airport or airspace, many end up being "permanent" and properly classified, so important info gets buried in the deluge.

Ops Group and ICAO want to reduce the number of codes in use and weed out the "permanent" notices so that appropriate notices can be prioritized and pilots only needs to be concerned with relevant notices, rather then wading through hundreds of pages looking for critical info, like it is now.
