What is the purpose of a Flight Permit?

A Flight Permit is specifically designed to authorize the operation of an aircraft that may not meet all the standard certification requirements for a regular airworthiness certificate. This is particularly relevant for experimental aircraft or certain types of microlights, which may have limitations regarding their use and operational capabilities.

In this context, when the option refers to permitting the operation of a specific two-seat microlight, it accurately reflects the purpose of the Flight Permit. The regulatory framework often includes provisions for such permits that ensure these aircraft can be operated safely while still complying with certain restrictions set forth by aviation authorities.

The other options capture scenarios that fall outside the primary function of a Flight Permit. While regulations exist for multiple aircraft operations, international flight certification, and maintenance exemptions, none of these scenarios align with the specific purpose of a Flight Permit as it pertains to authorizing flight for an aircraft type that requires special permission, such as a microlight.
