What does RAC refer to in technical publications?

RAC refers to "Rapid Action Change" in technical publications. This term is used to describe a type of change that is issued when there is an urgent need to correct, modify, or update information in a publication as a result of new data, safety concerns, or operational requirements. Rapid Action Changes are designed to prompt immediate attention from the users, ensuring that they are informed of critical updates without delay, which is essential for maintaining safety and operational efficiency in aviation.

The use of RACs highlights the importance of keeping technical documents current and the need for prompt dissemination of critical information. They are particularly important in scenarios where delays could lead to safety compromises or operational inefficiencies. This emphasis on timely updates distinguishes RACs from other forms of changes, which may not require immediate action or may pertain to less urgent matters.
