Time Based Separation (TBS) will come into operation at Heathrow Airport from the end of March 2015. The system being installed for Heathrow has been jointly developed by NATS and Lockheed-Martin and will be a world first implementation of Time Based Separation. TBS is expected to become the norm for capacity constrained airfields in the coming years.
The Time Based Separation system and procedures are expected to significantly reduce inbound Air Traffic Flow Management and airborne holding delays that result from the impact of headwinds on final approach.
NATS has produced a short video to explain the context, with a briefing sheet and the associated Aeronautical Publications.
