Heathrow has now submitted its planning application for the second phase of taxiway changes to allow full, post-Cranford, alternation on easterlies.
Last year's application covered the RETs on 09R, which are currently being built in conjunction with the 09R/27L runway resurfacing programme.
The latest application is to facilitate sustained departures on 09L, with an additional access taxiway (A13E) to be built between A12 and A13, plus a new link between Alpha and Bravo taxiways immediately to the south of the new RAT. Minor additions will also be made to the fillets on A12 and A13 "to enable A380 aircraft to access and exit the runway to meet the safety requirements of the CAA" (how do they manage at present?).
The plan also includes a 5 meter high Longford noise barrier along the line of the Duke of Northumberland River.
