Known as Notices to Airmen, and now also Notices to Air Missions, NOTAMs are a critical source of knowledge for aviators around the world. As defined by the United States FAA, they “contain information essential to personnel concerned with flight operations but not known far enough in advance to be publicised by other means”.

 

They share abnormal statuses such as temporary hazards and act as a valuable tool for keeping our skies safe. With space often tight and time at a premium, a series of abbreviations are used within NOTAMs to disseminate information efficiently. 

 

This week on the Key.Aero commercial aviation quiz, we’re putting your knowledge of some of these official ‘contractions’ to the test. Good luck!
