India's Directorate General of Civil Aviation (DGCA) set a noise limit for the aircraft purchased by airlines operating in India (Hindustan Times, 10-Feb-2011). The rule applies to aircraft manufactured after Jul-2011 and not to airlines' existing aircraft fleet. According to the rule, new aircraft would be cleared for use only if the noise emitted 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 on an aircraft.

Global commercial aircraft deliveries fell in 2016 as Boeing again outsold Airbus; 2017 to be a peak
The global commercial aircraft fleet grew by 4% in 2016 and the year ended with an order backlog of more than nine years of production. Among the regions, North America still has the biggest and oldest fleet, but the lowest ratio of orders to aircraft in service. By contrast, Middle East has the fewest in service, but the highest ratio of orders to current fleet numbers.
This report gives an overview of the number of commercial aircraft deliveries in 2016 and the outlook into 2017 and beyond. It also looks at numbers in service and on order by region. It is based on preliminary numbers from the CAPA Fleet Database and guidance on 2016 deliveries from Airbus and Boeing, who have yet to announce final numbers.
The data indicate that total worldwide deliveries fell in 2016, the first such decline for six years, as a result of delays to new aircraft programmes. Boeing delivered more aircraft than Airbus for the fifth straight year, but its deliveries fell short of its 2015 level, while Airbus increased its numbers year-on-year. Total deliveries will likely rise again in 2017, but this may prove to be a peak year.
Airports - subject as always to the vicarious uncertainty of airline fortunes
CAPA’s 2016 outlook was against a background of unusually high levels of profitability for airlines.
