Ace the Skies: 2026 Aviation Regulations Practice Test – Soar to Success!

A first class medical certificate for a pilot under 40 years old is valid for a period of five years. Since the certificate was issued on October 21, the expiration date will be exactly five years later, maintaining the same date, which is October 21. However, the aviation regulations typically state that the certificate remains valid until midnight of the expiration date. Consequently, if the certificate is set to expire five years from October 21, it will indeed last until midnight of that same date, making the effective expiration of this specific certificate October 21, 5 years later.

In this context, even though the answer references October 31 as a date within the choices provided, the correct understanding of expiration for a first class medical certificate is crucial: it extends until the end of the designated expiry date rather than falling on a preceding date, allowing the pilot to utilize the certificate’s validity clearly defined by its specific issuance date.
