In the latter case, it is considering a so-called 'mixed mode' scheme, whereby both runways are used for take-off and landing. The current 'alternation' system means flights take off on one runway and land on the other, alternating once a day to limit the noise burden on local residents.
Baugh said he will spearhead consultations with airlines, local authorities, environmental groups, MPs and residents. He will report to Heathrow director of communications Ben Morton.
He replaces head of public affairs Gill Kirk, whom a spokeswoman said had quit to start her own consultancy, Lyric Communications. BAA is also considering appointing a head of community relations for Heathrow to work alongside Baugh.
Baugh joined AS Biss three years ago. His clients have included BT, the RAC, Nationwide and the Civil Aviation Authority. Prior to that he was head of comms at the Amalgamated Engineering and Electrical Union (now Amicus).
