Which statement is true regarding Method 1 and Method 2?

The statement regarding Method 1 and Method 2 being only for planning purposes is accurate because these methods are typically utilized in the context of assessing flight operations, performance calculations, or safety evaluations that are conducted prior to the actual flight. This means they primarily serve a preparatory role, helping to ensure that pilots and operational staff have the necessary information to make informed decisions during the flight planning phase.

In several contexts of aviation, methods might be classified or designated as either real-time operational tools or as benchmarks for pre-flight assessments. If the other methods are utilized for real-time operations or required during flight, it underscores that Method 1 and Method 2 serve a different purpose focused on planning and preparation. As a result, recognizing their purpose as confined to planning helps clarify their role in the overall flight operation framework.
