What is a NOTAM in aviation?

A NOTAM is a kind of notice (A notice to an Airman or a notice to an Air Mission) containing essential information about the flight route or its location. In these unclassified notices, those flight operations are mentioned that could affect aviation. 

By using special concentrated characters the language in these notices (i.e NOTAMs) is become unique and needs to be decoded by the aviation authority.
