A residents group wants a guarantee that planes will be quieter after London City Airport submitted plans to build a larger terminal building and a new taxiway.

The airport, which was opened by the Queen in 1987, launched a public consultation last year on its plans for major improvements for the next 30 years.

These are part of the City Airport Development Programme and include a larger terminal building, new hard aircraft stands and a new taxiway. At its heart are larger aircraft due to fly from the airport that need larger stands and a taxiway to get to the runway and make full use of it.

A spokeswoman for the airport said: “The larger aircraft refers to the next generation of aircraft expected to come into circulation in the next few years. The manufacturer’s data states that the aircraft will be quieter and more fuel efficient than the existing aircraft operating out of LCY.

“The airport is closely monitored by Newham Council and this includes strict noise controls. New aircraft are subject to noise trials to ensure they meet the criteria before they are permitted to operate from the airport.

HACAN East, the organisation which represents residents under the London City and Heathrow flight paths, is concerned that City Airport’s expansion plans will result in more noise across East and South-East London.

The airport is proposing to undertake a lot of work on its runway and taxiways to allow bigger planes to use the airport. It is also proposing to expand the terminal, build a hotel and create more parking.

HACAN East chair, John Stewart, said, “City Airport claims that the new planes will be quieter than the large aircraft currently using the airport. But residents need a caste-iron guarantee that the planes will actually be quieter”

A spokesman for Newham Council confirmed that an application had been received and that plannining officers were validating it.
