What must a pilot do when a PPC has lapsed for more than 24 months?

When a pilot's PPC (Pilot Proficiency Check) has lapsed for more than 24 months, the regulations require the pilot to retake initial training. This is due to the significant amount of time that has passed without the necessary proficiency checks, which can affect a pilot's skills and knowledge regarding aircraft operation and safety protocols. Initial training ensures that the pilot is fully up to date with the necessary skills, regulations, and practices before they are allowed to fly again.

The requirement to retake initial training emphasizes the importance of maintaining high safety standards and ensuring that pilots are adequately prepared to operate aircraft safely and effectively. Refreshing foundational skills through initial training is crucial for aviation safety, given the potential for rapid changes in aviation technology and regulations over an extended period.
