Final answer:
The question addresses air traffic control procedures for separating aircraft at the boundary of radar and nonradar controlled airspace. While FAA regulations for standard aircraft separation are provided, the specific separation distance required when the antenna site is over 40 miles away is not mentioned in the details provided, necessitating a reference to FAA guidelines or the Air Traffic Control manual.
Step-by-step explanation:
The question pertains to the separation of radar-controlled aircraft from the boundary of airspace where nonradar separation is in use when the antenna site is more than 40 miles away. In air traffic control, maintaining a safe distance between aircraft to avoid collisions is crucial. When we consider an effective air defense perimeter with an estimated radius of 30 nautical miles for a confirmed or possible Surface-to-Air Missile (SAM) site, it is clear that separation standards must be stringent to ensure the safety of aircraft.
The Federal Aviation Administration (FAA) regulates the flight paths of commercial airliners to maintain safety. According to the FAA's regulations, there is a specific required separation of five miles laterally for aircraft at the same altitude and a vertical separation of 2,000 feet, or 1,000 feet if below 29,000 feet in altitude. Nevertheless, the specific answer to the student's question regarding the separation in miles when transitioning from radar to nonradar airspace control is not provided within the information given, which suggests that we must refer to the FAA's established procedures or consult the Air Traffic Control manual for the exact separation mileage.
