Tactically Enhanced Departures (TED) were operated in Phase I of the Operational Freedom Trials.
TEDs were only enacted on eight individual days and to 38 departures out of a
total of approximately 55860 westerly departures (approximately 0.07%). This
limited application of TEDs during the trial can be explained by the restrictive
structure of Heathrow’s established departure routes. The established departure
procedures are designed for use at an aerodrome with “dependent‟ runways,
with all their attendant vortex separation, speed table and geographical direction
requirements, and consequently do not readily support simultaneous departures
from both runways. As such, within the current departure route structure, the
application of TEDs often resulted in detrimental impacts onto the arrival flow of
aircraft and was perceived to hinder, rather than support, the overall operation.

It wasn't planned to do any more in Phase II (which is coming to an end this month)
Give it a few hours and the data from yesterday should be available for view at
