Final answer:
Three clearance procedures which provide arriving aircraft with a seamless transition from the en route structure to the terminal environment are ``Radar vectors, Visual approach, Transition route.`
The correct answer is option c
Step-by-step explanation:
These three clearance procedures provide arriving aircraft with a smooth transition from the en route structure to the terminal environment
Let's understand each of these procedures:
1) Radar vectors: This procedure involves air traffic controllers providing navigational guidance to the pilot of an aircraft by issuing headings and altitudes. Radar vectors help the aircraft navigate from its current position to a specific point along its approach path.
2) Visual approach: A visual approach is a procedure where pilots navigate and land the aircraft visually, using visual references such as landmarks or the runway environment. This procedure is typically used when weather conditions permit and the pilot has adequate visibility.
3) Transition route: A transition route is a designated airspace corridor that connects the en route structure to the terminal area. It allows aircraft to make a smooth transition between different phases of flight, such as from cruising altitude to the initial approach fix. Transition routes are pre-determined and can be found on charts and approach plates.
By utilizing these clearance procedures, air traffic control and pilots work together to ensure a seamless transition from the en route structure to the terminal environment. This helps maintain safety and efficiency in air traffic operations.
The correct answer is option c) Radar vectors, Visual approach, Transition route.
