Sleep well, honey, noisy planes will be put to bed too

New Delhi: Planes with noisy engines will no longer be allowed to take off or land at night at Delhi’s Indira Gandhi International Airport, bringing relief to residents living nearby.
“No aircraft operator shall operate Chapter 2 aircraft to/from IGI airport under any circumstances between 2200 hours and 0600 hours with effect from October 31, 2010,” an aviation environment circular issued by the Directorate-General of Civil Aviation said.
The circular was issued on a Delhi High Court directive following complaints about the noise by JNU students and residents’ bodies in areas near the airport.
The rule is in line with the environment-friendly regulations of the International Civil Aviation Organisation, which define Chapter 2 aircraft as those mostly powered by noisy turbojet engines. Most of these aircraft were manufactured during the late 1970s.
The difference between a Chapter 2 and a Chapter 4 aircraft, being produced now, is similar to that between a car of the pre-pollution-control era and a Stage-III car whose engines emit much less noise and smoke. The new-generation aircraft are about 75 per cent quieter than those built 40 years ago.
