Which of the following is required for VFR operations according to the regulations?

In the context of Visual Flight Rules (VFR) operations, appropriate planning and authorization are essential components to ensure safety and compliance with regulations. This planning involves understanding weather conditions, airspace restrictions, and potential obstacles in the route of flight. Pilots must assess their ability to maintain visual references to the ground and avoid controlled airspace when necessary.

Planning is also critical for determining the aircraft's airworthiness and ensuring reliance on current navigation information, as well as adhering to any specific requirements that may pertain to a particular flight or airspace. Authorization may be needed when flying in certain controlled airspace or when specific conditions apply, demonstrating the importance of both planning and regulatory compliance prior to VFR operations.
