The Clarity and Accessibility of NOTAM Information for the Aviation Industry

This report was commissioned by the Bureau of Air Safety Investigation (BASI) to investigate the system of Notices to Airmen (NOTAM) following statements from some airline flight crews that current NOTAM presentation is not optimised to meet their needs. Pilots had stated that:

• Some NOTAM are not clearly written,
• The NOTAM format can be difficult to decipher,
• There is too much irrelevant information provided.
