When should pilots inform ATC about their runway choice?

Pilots should inform ATC about their runway choice when it is operationally advantageous. This means that if the pilot believes that a particular runway will facilitate a more efficient operation or enhance safety—due to factors such as wind direction, runway length, surface conditions, or traffic considerations—they should communicate this to air traffic control. This proactive approach allows ATC to consider the pilot's preferences while managing overall airport operations, leading to smoother and safer traffic flow.

When conditions are adverse, these may prompt more specific communications with ATC, but the pilot's choice should still focus on what serves their operation best. While it’s important to communicate runway choices under various circumstances, such as emergencies or adverse conditions, the most effective time to assert runway preferences is during routine operations when it can optimize the flight’s efficiency and safety. Therefore, suggesting that pilots should provide this information only during emergencies or at all times can dilute the strategic focus on operational advantage that enhances both pilot decision-making and ATC responsiveness.
