Claim: Time based separation, now a part of the SESAR Deployment Programme, resulted to a significant decrease in arrival delays due to headwinds, after being successfully implemented at Heathrow to address headwind disruptions by reducing the spacing between pairs of aircraft.
Evidence: Furthermore, TBS is now a part of the SESAR Deployment Programme. The impact of strong headwinds on an aircraft's speed during approach results in decreasing landing rates, generating delays and cancellations at airports with a significant cost to airspace users and the travelling public. TBS addresses headwind disruptions by reducing the spacing between pairs of aircraft. Time Based Separation was successfully implemented at Heathrow by NATS and Leidos working in conjunction with Heathrow Airport on 24 March 2015 and has been in continuous operation since then.
