TLDR: An Aeronautical Information Publication (AIP) is a manual that contains important information for pilots and air navigation. It is issued by the government and covers regulations, procedures, and other details related to flying in a specific country.
An Aeronautical Information Publication (AIP) is a publication that provides essential information for pilots and air navigation. It is issued by the government or a relevant authority in each country. The purpose of the AIP is to provide detailed information about regulations, procedures, and other important information that pilots need to know when flying in a specific country.
The AIP is divided into three main parts: GEN (general), ENR (en route), and AD (aerodromes). Each part contains specific information related to different aspects of air navigation. For example, the AD section includes details and charts of all public aerodromes, while the GEN section covers general information and procedures.
To ensure that the AIP is up-to-date, it undergoes regular revisions on a fixed cycle. These revisions are made according to the AIRAC (Aeronautical Information Regulation And Control) cycle, which was introduced in 1964. The AIRAC cycle consists of either a 56-day cycle or a 28-day cycle, depending on the significance of the changes. Pilots and other users of aeronautical data receive these updates well in advance so they can update their flight management systems accordingly.
In some countries, the AIP is informally known as the "Airman's Manual" or the "Air Pilot." This reflects its importance as a comprehensive guide for pilots and air navigation.
In recent years, there has been a shift towards electronic AIPs (eAIPs). These digital versions of the AIP are available in various formats, including PDF, and are designed to be more user-friendly for reading on screens and for electronic data exchange. Many countries now provide digital AIPs on CD-ROM or through websites.
Overall, the Aeronautical Information Publication (AIP) is a crucial resource for pilots and air navigation. It provides them with the necessary information to ensure safe and efficient flights.
