Designing airframes and engines to reduce the noise

Improving operations

The UK's airports, airlines and ATC are doing lots to reduce the noise by changing how the planes are operated.

Financial incentives – the carrot and stick

Every airport charges airlines to use its facilities, with the level of the charge per plane regulated by the CAA.

To reduce noise levels further, we have worked out a discount scheme for airlines that use the quietest aircraft, so that they have an incentive to use quieter planes. But if an airline uses noisy planes, we’ll actually charge them more to use the airport.

This scheme means that the noisiest planes can end up paying three times the normal landing charge, while many pay one and a half times the charge. On the other hand, the airlines with the quietest planes pay less than the normal charge – just 90%.

Even though our landing charges are competitive, the scheme encourages airlines to use their quietest fleet.
