What is the main advantage of TBS over traditional separation methods?

The primary advantage of Time-Based Separation (TBS) systems is that they utilize time instead of distance for ensuring safe separation between aircraft. By focusing on time, TBS can allow for a more flexible approach to managing aircraft in busy airspace, particularly during approaches and landings. This method helps optimize the flow of air traffic by accounting for variations in aircraft speed and patterns, providing a more efficient operation than traditional distance-based separation methods that are often less adaptable to changing conditions.

Utilizing time allows controllers to maintain safe intervals between aircraft while also potentially reducing delays and increasing the number of aircraft that can land or take off in a given timeframe. This is especially beneficial during peak traffic periods or in busy terminal environments where traditional methods may not provide the same level of efficiency.

While distance-based separation focuses on maintaining a specific space between aircraft, TBS allows controllers to make more nuanced decisions about spacing based on real-time conditions, which can enhance overall safety and efficiency in air traffic management.
