In what situation is it acceptable for a pilot to not have their current pilot certificate readily accessible?

The correct answer emphasizes that there is no acceptable situation for a pilot to not have their current pilot certificate readily accessible during flight operations. Regulations dictate that pilots must carry their certificates at all times when exercising the privileges of their pilot certificate. This requirement ensures that pilots can provide proof of their qualifications to authorities whenever necessary, particularly during inspections or emergencies.

While there might be scenarios where a pilot is not actively checked for their certificate, such as post-flight checks, the essence of aviation safety and regulatory compliance mandates that the certificate be on hand at all times when flying. This includes all forms of flight operations, whether solo, as part of a crew, or during ferry flights. The requirement reinforces accountability and safety within the aviation community, ensuring that only properly certified pilots are operating aircraft.
