Claim: Time based separation, now a part of the SESAR Deployment Programme, was not able to make any reductions in arrival delays due to headwinds, after being successfully implemented at Heathrow.
Evidence: In early 2000, EUROCONTROL started researching Time Based Separation (TBS), a new operating procedure for separating aircraft by time during strong headwind conditions, instead of distance. Furthermore, TBS is now a part of the SESAR Deployment Programme. Results have been very successful with a c.62% reduction in arrival delays due to headwinds and a marked improvement in overall airport punctuality.
