Some residents, including community group Flightpath Watch, are concerned the extended hours and flight path changes will bring bigger business jets and noisier aircraft to the borough.
Last week a spokesperson for the group told News Shopper: “Any new GPS route is a requirement for a commercial airport, not a benefit for the residents.
“It will bring more noisy business jets and larger aircraft to the borough.
“Our greatest concern is that noise at unsocial hours is detrimental to the well being of residents and their productivity at work or school.
“Flight paths are important, but are a secondary consideration to the hours.”
Other people living in the borough fear allowing the airport to expand will eventually lead to commercial and holiday flights.
But airport managing director, Will Curtis, insists this is not the case and that extending the hours will actually prevent this from happening.

In an open letter to residents published last month, he said: “You can take it from me that we don’t want scheduled or holiday airlines at Biggin Hill Airport, we don’t need new runways and we don’t want to expand beyond our existing airport boundary.
“I live in Biggin Hill, and I don’t want to see a mini-Luton type airport on my doorstep and I know that you do not want that either.”
