Which situation is NOT given first priority?

When managing air traffic and prioritizing situations, it's important to understand the urgency and implications of each scenario.

An aircraft experiencing a malfunction is a critical situation that demands immediate attention, as it might lead to a dangerous scenario if not addressed quickly. Similarly, an emergency landing request is one of the highest priorities because it directly involves the safety of the aircraft and those onboard.

While minimum fuel declarations are serious, they do not equate to an immediate emergency, as they provide the pilot with some latitude to either divert or adjust. The declaration signals that the aircraft is running low on fuel, but it does not necessarily require immediate action like a malfunction or emergency landing would.

Reporting turbulence, while it can impact the safety and comfort of a flight, does not pose a level of immediate danger requiring priority handling such as malfunctions or emergencies do. Therefore, among the scenarios presented, a declaration of minimum fuel is typically handled with less urgency than emergencies or malfunctions, making it the situation that does not receive first priority.
