Which flights are subject to required preflight action concerning weather reports and fuel requirements?

The requirement for preflight action concerning weather reports and fuel requirements applies primarily to flights that are not in the vicinity of an airport. This is because when operating outside of an airport's vicinity, a pilot must be more vigilant about their operating conditions, including potential adverse weather and ensuring they have adequate fuel for the planned flight. Without immediate access to an airport, the pilot has greater responsibility to assess the weather and fuel levels to ensure safety throughout the flight. This is essential to avoid situations that could lead to an emergency landing or running out of fuel.

In contrast, flights conducted for compensation or hire also have specific regulations, but the emphasis on weather and fuel applies equally to other flight circumstances rather than their compensation status. Although IFR flights have their own set of regulations that include weather considerations, this does not encompass all flights, making them less comprehensive than the requirement for preflight action not in the vicinity of an airport. Lastly, the requirement does not limit itself to flights above 10,000 feet MSL as safety concerns regarding weather and fuel apply regardless of altitude.
