• According to the FAA’s website, “a NOTAM is a notice containing information essential to personnel concerned with flight operations but not known far enough in advance to be publicized by other means.
• NOTAMs basically provide information about potential hazards or changes to flight operations that may affect safety.
  • Eg. - Without NOTAMs, aeroplanes are at a risk of running into flocks of birds or remaining unaware of slippery conditions on runways.
• NOTAM is different from air traffic control system that helps in keeping planes at safe distance from each other while on air.

• Pilots are typically required to check NOTAMs before taking off in order to ensure that they are aware of any hazards or changes that could impact their flight.
• Overall, the NOTAM system is an important tool for ensuring the safety and efficiency of flight operations by providing pilots and other aviation professionals with critical information about potential hazards and changes to flight operations.
