Pre-Flight Information Bulletins (PIBs)

PIBs are a recapitulation of valid NOTAMs of operational significance. The AIS Briefing Tool provides several types of PIBs, tailored to different operational needs:

Aerodrome PIB: Focused on specific aerodromes. Includes NOTAMs relevant to departure, destination, and alternate airfields.
Area PIB: Covers NOTAMs within selected Flight Information Regions (FIRs). Excludes aerodrome-specific notices.
Zone PIB: Based on a geographic area defined by a polygon or point-and-radius. Useful for specific operational areas.
Route PIB: Generated using selected aerodromes and FIRs. Suitable for end-to-end flight planning.
Narrow Route PIB: Similar to Route PIB but more precise, using a route buffer (default 20NM) to filter intersecting NOTAMs.
Point PIB: Created around a single point (Lat/Long) with a defined radius. Ideal for checking activity near a specific location.

PIBs are available via the briefing tool to registered users.

Contingency PIBs

In the event the main NATS briefing portal is unavailable, you can still obtain essential briefing data via the Contingency PIB site, which provides Contingency Pre-Flight Information Bulletins (PIBs). These are maintained separately to ensure continuity of access and operational integrity during system outages.
