Around message 2800 in September 2013, people were all talking about the CAA Safety Notice on changes to wake turbulence separations for heavy-heavy departures.
The Heathrow UK AIP document
EG_AD_2_EGLL_en_2014-04-03.pdf
still seems to refer to the old standards :
(iii) Departures – Wake Vortex separation.
Wake vortex separations are in accordance with the 5 Group Scheme and are as detailed in UK AIC P 072/2010. On
departure, when in receipt of line up clearance, the pilot must inform ATC if greater wake vortex separation will be
required behind the preceeding aircraft than that laid down in UK AIC P 072/2010. Failure to do so may resut in
additional delay.
but those standards were cancelled on 20th February and superseded by

Does Heathrow operate now with the "new" ICAO standards ?
Has a case to do anything else, as was surmised previously, been put forward ?
