We have previously discussed NOTAMs and their use within UAV operations and the importance of knowing your airspace and procedures for working safely.  Recently we had some discussions with NAV Canada via the Halifax FIC regarding the format for submitting NOTAMs that involve UAVs. Here are the formats that should be published in the next edition of the NOTAM Procedures Manual.
