In our area, it is often possible to hear the low frequency `thwap-thwap' of the main rotor blades 30 seconds before the helicopter appears. Then there is the whine from the gearbox and higher pitched noise from the tail rotor blades as it passes overhead. Sometimes the `Noise' is sufficient to pulsate the air in our House and rattle light fittings. From a human hearing (phsyco-acoustic) viewpoint, Helicopter noise has also been rated as 10-15 decibels more annoying than noise from conventional Aviation, for the same reading on a Noise Meter. Also a medium size `Executive' helicopter has a high carbon and air pollution footprint, as some only do 2 miles per gallon and the exhaust gas is not cleaned up. Helicopters benefit few people (excepting Air Sea Rescue, and the Air Ambulance) and blight many peoples lives. It is time for a radical rethink and restrictions – like Paris – on their use in the crowded South East of England (and the Lake District too apparently ….) . Finally it is almost impossible to read the Registration Number on an overflying Helicopter, so there is little chance of reporting specific dangerous or nuisance flying. This also needs review, and perhaps `tachographs' or similar in the Cockpit.
