Which Emergency Access Route is labeled as ER 3?

The Emergency Access Route identified as ER 3 is indeed the Service Road. This designation is critical because the Service Road is specifically designed to facilitate emergency vehicles and personnel to access various areas of the airport swiftly. This ensures rapid response during any situations that may arise, such as accidents or emergencies, helping to maintain safety and mitigate risks effectively.

The other options serve different purposes within the airport’s operational structure. Glide Path Road is intended primarily for aircraft navigation and instrument landing systems. The Arrival Zone is tailored for passenger drop-off and pick-up activities. The Paved Runway is exclusively for aircraft takeoff and landing operations. Each of these routes is vital to the functioning of the airport but does not serve the specific purpose of an emergency access route as designated by ER 3.
