What is a standard terminal arrival route (STAR)?

A standard terminal arrival route (STAR) is designed specifically to ensure efficient and orderly approaches to an airport. These routes provide pilots with a predetermined path from the en-route phase of flight to the final approach, allowing for smoother traffic flow and reduced workload for air traffic controllers and pilots alike.

By utilizing a STAR, aircraft can descend in a structured manner that minimizes holding patterns, reduces communication congestion, and enhances safety as they enter busy airspace surrounding airports. This system is particularly beneficial in high-traffic areas where numerous flights may be approaching the same airport simultaneously. Efficiently managing the arrival of multiple aircraft helps to maintain safe separation and optimized airspace utilization.

This option directly aligns with the purpose of a STAR, contrasting with the other choices, which do not accurately describe its function. For instance, a predefined route for takeoff relates to departure procedures rather than arrival management, while airspace restrictions focus on limitations and constraints that may apply to specific airspace. The concept of maximizing cruising altitude does not pertain to STARs, which focus on the arrival phase of flight rather than the cruising phase.
