European NOTAM office hours typically follow standard business hours and standby personnel are available 24/7 to process urgent NOTAMs.
The European Notice to Airmen (NOTAM) office hours vary by country, but typically they operate during standard business hours, which can range from 8:00 to 17:00 local time. In the case of urgent notices that concern the safety of aircraft operations outside of these hours, standby personnel are available to process NOTAMs on a 24-hour basis, ensuring that important information is disseminated without delay, regardless of the time or day. The continuous availability of standby personnel for processing NOTAMs is critical for maintaining air traffic safety and efficiency.
So, European NOTAM offices have set business hours for regular operations, while standby personnel are prepared to process NOTAMs at any time outside of those hours to uphold the safety and smooth functioning of air traffic.
