The AIP (Aeronautical Information Publication) of Belgium and Luxembourg is available in both paper and electronic (eAIP on CD-ROM) format.
The eAIP is adapted 13 times a year. Every amendment (AMDT) is published according to the ICAO AIRAC cycle, that means every 28 days. This cycle is a calendar with worldwide common dates on which new aeronautical information shall become effective.
Furthermore, Belgocontrol publishes supplements (SUP) to the AIP and aeronautical information circulars (AIC).
The electronic AIP (eAIP) was developed with the XML technology according to Eurocontrol technical specifications.
More detailed information on the eAIP is available on the Eurocontrol website.
