Operations notices

This regulation requires airlines (certificate holders) to keep their operations personnel informed about changes that affect flight operations. When there are changes to equipment, operating procedures, navigation aids, airports, air traffic control procedures, regulations, or local airport rules, the airline must notify the appropriate staff.

The airline must also communicate known flight hazards, including icing conditions, other dangerous weather, and problems with ground or navigation facilities. The key word is "known"—the airline must share information it becomes aware of that could affect safety.

In practice, this ensures pilots, dispatchers, and other operations staff stay current on anything that might impact how they plan or conduct flights. Airlines typically fulfill this requirement through bulletins, notices, briefing materials, or electronic notification systems. This helps maintain safety by ensuring the people making operational decisions have up-to-date information about the operating environment.
