What sign indicates you are clear of the ILS critical area while clearing an active runway?

The sign indicating that you are clear of the ILS critical area while clearing an active runway is typically a specific design used within airport operations to denote the boundaries of this area. When a pilot or air traffic controller observes this sign, it signals that the ILS (Instrument Landing System) critical area is not being encroached upon, which is crucial for ensuring safe landings and takeoffs, particularly in low visibility conditions.

In this context, Illustration H is the correct depiction reinforcing the importance of being aware of such critical areas around runways. It shows that once you have passed this sign, you are properly positioned outside of the critical region, allowing for safe operations of aircraft using the ILS. Understanding the specific visual cues and signs around runways helps in maintaining safety protocols at airports.

In recognizing the significance of these signs, one can appreciate how they play a vital role in airport safety and operations by preventing potential interference with aircraft landing and takeoff procedures.
