An hourly updated archive of all UK Notices To Airmen (NOTAM), along with all other pre-flight information bulletins (PIB) and briefing sheets.
The data is fetched from the NATS AIS Contingency system as it provides the feeds without authentication.
NATS says: The above file contains all UK NOTAM valid at the time of generation and within the next 7 days, it is provided by the EAD system with no declared xml schema and therefore may be subject to change with minimal notification.
PDF Briefing Sheets for situations of operational significance can be found in the briefing_sheets directory.
