Airline-Specific Risks & Pain Points

FAA NOTAM System outages (e.g., Jan 2023 FAA NOTAM system failure grounding 10,000 flights) can break AFTN feed with no automatic failover to backup source

Legacy free-text NOTAM format (pre-ICAO Digital NOTAM standard) leads to high parse error rates, especially for non-standard national formats from international destinations

Incomplete Q-lines from some national NOTAM offices require manual correction, creating dispatcher workload spikes during high-NOTAM-volume periods (e.g., airshow TFRs, VIP TFRs)

Overly broad geographic filters result in NOTAM overload — dispatchers report reviewing 200–400 NOTAMs per long-haul release; filter tuning is manual and not route-aware

Automated severity scoring relies on Q-code purpose field, which is inconsistently applied by international NOTAM offices — human review remains mandatory for all Critical-category items

Dispatchers managing 30–50 concurrent flights face decision fatigue during high-tempo NOTAM periods; no AI-assisted triage available in current Jeppesen version
