What must a private pilot practicing with passengers do regarding operating expenses?

A private pilot practicing with passengers is allowed to share the operating expenses of the flight, provided they adhere to specific regulations. The selected answer highlights that the pilot must not pay less than the pro rata share of operating expenses. This means that if multiple people are on board, costs such as fuel, oil, rental fees, and other operating expenses should be shared equally among all participants in the flight.

This arrangement allows private pilots to engage in flying with others without violating regulations that govern compensation for services. It's important for pilots to understand that they cannot accept payment that exceeds their share of the costs, as doing so could classify them as operating for compensation or hire, which would require a higher level of certification or permission from regulatory bodies. By ensuring that expenses are divided fairly, the pilot can enjoy the benefits of sharing the flying experience with others while remaining compliant with aviation regulations.

The other possibilities either suggest no contribution to costs or inequitable sharing, which does not align with regulatory requirements for private pilots.
