All fixed-wing aircraft are issued an emergency marshal radial of 150 degrees.

Emergency marshalling relies on a single, standard reference direction so every marshal and pilot share the same guidance during an emergency. A radial is a line from a central point that defines direction, measured in degrees from magnetic north. Issuing all fixed-wing aircraft a 150-degree radial gives a consistent path for directing aircraft away from active areas and toward safe holding or parking, enabling quick, unambiguous communication when time is critical. This specific direction is chosen because it typically places the aircraft in a safe, practical sector that avoids conflicts with runways and busy taxiways across many airfields. Other directions would place aircraft into zones where visibility, spacing, or traffic conflicts are more likely, making 150 degrees the sensible, standard choice.
