NATS and Leidos target more TBS improvements beyond 2018

20 April 2017

NATS is continuing to improve its Time Based Separation (TBS) tool at Heathrow, in partnership with Leidos.

Since March 2015, when the UK air navigation service provider introduced TBS at Heathrow with Leidos (then Lockheed Martin), airlines flying into the UK hub have improved arrival rates and reduced delays associated with headwinds.

In pursuit of further benefits, NATS and Leidos aim to introduce Enhanced TBS at Heathrow in early 2018. This capitalises on revised wake turbulence categories and associated separation minima set out in the European Wake Vortex Re-categorisation (RECAT-EU) programme.

RECAT-EU essentially updates ICAO wake vortex separation rules that date from the 1970s, by dividing the existing Heavy and Medium categories into two sub-categories.
