Airport and Ground Operations Practice Exam

Airfield signage helps you know exactly where you are. A Runway Location sign specifically identifies the runway you are on by displaying the runway designator in a distinct black sign with yellow lettering. This lets you confirm you’ve entered or are departing from the correct runway, which is crucial for safe taxi and takeoff operations.

By comparison, a Taxiway Location sign shows which taxiway you’re on, not the runway. A Runway Distance Remaining sign tells you how much runway is left ahead, useful for landing or rollout but not for identifying the runway. An ILS Critical Area Boundary sign marks the edge of the protected ILS area, not the runway identity.

So, the sign that identifies the runway on which the aircraft is located is the Runway Location sign.
