Noise limit for aircraft

Mumbai: Residents living close to the city airport could have a less noisy environment in the near future. The Directorate General of Civil Aviation (DGCA) on Wednesday set a noise limit for the aircraft purchased by the airlines operating in India. However, the rule applies to aircraft manufactured after July this year and not to airlines’ existing aircraft fleet, said Bharat Bhushan, DGCA chief.
On an average, a flight takes off or lands every two minutes at the city airport. The operator records the airport’s noise levels once a month but the government has not laid down a specific noise limit for airports.
The new noise norms could be critical because daily flight movement in the city is projected to touch 750 take-offs and landings by 2014 from the present 620 odd daily movements. The second airport at Panvel, which is likely to be partially operational by 2015, will raise this figure considerably.
According to the rule, new aircrafts would be cleared for use only if the noise emitted from their engines is within the limit prescribed by the airline regulator.
Noise levels would be tested at three stages — take-off, landing and when the aircraft is airborne but close to the ground. The airline regulator has prescribed noise limits on the basis of the number of engines in an aircraft.
