Time-based Separation Pays Off at London Heathrow
System is working better than expected and is on track to eliminate 80,000 minutes of delays at the airport in just three months.

UK air navigation service provider Nats and partner Lockheed Martin said the time-based separation (TBS) arrival system they deployed at London Heathrow Airport in March is working better than expected. It's on track to eliminate 80,000 minutes of delays at the airport. TBS uses real-time wind data to calculate the optimum safe time between arriving aircraft, allowing separation distances to be reduced to maintain the landing rate.
