Where and when was TBS first introduced for final approach?

The correct answer reflects that Terminal Bypass System (TBS) was first introduced for final approach at Heathrow in 2015. TBS represents an important advancement in air traffic management, focusing on enhancing the efficiency of aircraft landings during busy periods. The deployment at Heathrow, a major international airport, highlights the system's relevance in handling high-density traffic scenarios. The choice of Heathrow also aligns with the airport's historical need for innovative solutions to manage the complex airspace and ensure safety while maximizing throughput.

In this context, the other options might reference the introduction of similar systems at different airports or highlight improvements implemented in the years mentioned but do not accurately reflect the initial deployment of TBS for final approach. Thus, the importance of understanding where TBS first made its mark aids in recognizing how the system has since evolved and been adopted in other regions for better traffic management.
