There are four weeks left to comment on plans to increase the number of planes from Stansted Airport flying over Braintree.
Residents could see the number of planes flying over their homes during the daytime more than double under plans to ease congestion above Heathrow.
It could mean up to 12 low-flying planes an hour, or one every five minutes.
Daily departures from Stansted Airport currently leave in two directions, with about 58 flying south-east towards Dover and 51 taking off east over the Braintree district towards Clacton.
NATS, which manages the country’s air traffic, is suggesting moving most of the daytime flights that use the Dover route to the Clacton route.
The consultation closes on September 8. Visit nats.aero/environment/consultations/lamp-stansted-sid-consultation
