Which type of altitude is specifically used for aircraft during approach and landing?

The type of altitude specifically used for aircraft during approach and landing is the minimum vectoring altitude. This altitude is crucial because it is the lowest altitude at which an air traffic controller can provide radar vectoring service to aircraft. It ensures that aircraft are at a safe height to avoid terrain and obstacles during the critical phases of approach and landing. By maintaining this altitude, pilots receive necessary guidance and clearance while safely navigating to the runway.

In approach and landing scenarios, having a designated minimum vectoring altitude helps in managing airspace efficiently, ensuring safety by providing adequate clearance over obstacles, thus enabling a smooth and safe descent toward the airport.
