If a pilot has not flown in three years, what must they do to maintain a current license?

To maintain a current license after being inactive for three years, a pilot is required to complete a training program, which may include a Pilot Proficiency Check (PPC). This is essential because a prolonged period without flying can lead to skill degradation, and regulatory authorities require pilots to demonstrate their competency before they can resume flying.

Engaging in a training program ensures that pilots refresh their knowledge and skills in operating an aircraft, and the PPC specifically serves to assess their proficiency. This approach not only helps bring pilots up to speed with any changes in regulations, procedures, or technologies but also ensures safety in flight operations.

While other options, such as taking a written exam or attending a flight safety seminar, could provide valuable knowledge, they do not fulfill the regulatory requirement of demonstrating flying proficiency. A medical examination is crucial for ensuring a pilot's fitness to fly but does not specifically address the skill competency necessary after a long break from flying. Hence, completing a relevant training program or PPC is the mandated step for recertification after an extended absence from flying.
