FIS-B Notams Not a Complete List, FAA Warns

Notams received via Flight Information Systems–Broadcast (FIS-B) over the ADS-B universal access transceiver (UAT) datalink network might be incomplete, the FAA is warning pilots. In a recent Information for Operators (InFO) bulletin, the agency said FIS-B Notams are limited to those issued in the past 30 days, even though older ones might still be active.

“As a result, FIS-B [aeronautical information] may not include all Notams that a preflight briefing includes,” the FAA noted. “[Aeronautical] information obtained solely via FIS-B should not be regarded as a thorough preflight briefing. FIS-B information may be used by the pilot for the safe conduct of flight and aircraft movement. However, FIS-B does not replace a thorough preflight briefing.”

To provide better guidance to users, the FAA is currently updating Advisory Circular 00-63, “Use of Flight Deck Displays of Digital Weather and Aeronautical Information,” the Aeronautical Information Manual, and Aeronautical Information Publication, to inform users of this 30-day limitation on FIS-B Notams.
