Jet/turboprop aircraft executing a radar approach shall be vectored to intercept final bearing no closer than what distance at a specified altitude?

When guiding jet or turboprop aircraft during a radar approach, a critical safety and efficiency standard is to ensure that they are vectored to intercept the final approach bearing at a safe distance and altitude. The answer stating 4 nautical miles at 1,200 feet is based on established procedures that prioritize maintaining safe separation and providing adequate time for the aircraft to stabilize on the final approach.

This distance allows for a proper transition to final approach, ensuring that the aircraft can adjust its path correctly without significant deviation or risk of inadequate altitude. The specified altitude of 1,200 feet is also aligned with safety protocols, as it typically provides enough clearance over potential obstacles and aligns with standard approach profiles.

Maintaining these distances and altitudes is essential for effective sequencing in busy airspace, minimizing potential conflicts with other aircraft, and ensuring a smooth transition from en-route flight to landing. It is crucial for air traffic controllers to adhere to these distances to ensure that the aircraft have sufficient time and space for the necessary maneuvers without compromising safety.
