GOVERNMENT OF INDIAOFFICE OF THE DIRECTOR GENERAL OF CIVIL AVIATIONTECHNICAL CENTRE, OPP. SAFDURJUNG AIRPORT, NEW DELHIAVIATION ENVIRONMENT CIRCULAR 2 OF 2011File No. 04-01/2010-AED Dated: March 25, 2011Subject:Monitoring of Aircraft Monthly Fuel Data.1. PurposeThe aviation industry is a product of contributor to social andeconomic development at the global and national levels. Growth in theaviation sector strongly reflects the pace and direction of economicgrowth and prosperity. However, environmental risks associated withaviation have increased, not only in terms of local air quality and noiseimpacts, but also with respect to carbon dioxide (CO 2 ) emissions andthe generation of contrails and cirrus clouds which have the potential tocause global warming and climate change.Although the contribution of aviation global emissions isrelatively low at about 3% of anthropogenic CO 2 emissions, with theprojected growth in aviation sector, it will become more serious in nearfuture. Therefore, there is an urgent need to control the environmentalrisk of aviation, especially in the context of predicted future growth intraffic.2. ApplicabilityThe provisions of this circular shall apply to all scheduled andnon-scheduled airlines (both Indian and foreign carriers) operating ondomestic and international routes.3. Requirements1

In line with ICAO’s mandate to reduce emission from aviationsector, it has been decided that all scheduled and non-scheduledairlines as mentioned in Para 2 shall monitor the fuel consumption dataof their respective aircraft fleet on monthly basis and file the same tothe DGCA.4. Calculating Fuel Consumption Data:For the purpose of reporting the total fuel consumption, the fuelused during a flight, the fuel consumed by the auxiliary power unit(APU) whilst the aircraft is stationary and any fuel that may be dumpedduring a flight shall be considered. A separate calculation shall bemade for each flight. Actual fuel consumption for each flight shall beused wherever possible. If actual fuel consumption data are notavailable, a standardized tiered method shall be used to estimate fuelconsumption data based on best available information. Actual fuelconsumption shall be determined using one of the two methodsdescribed below:Method A: contained Amountofinfuel contained AmountofinfuelFuel flight that subsequentuplift forFuelConsumptionaircraft tanks-aircraft tanksfor eachFlightonce fuelupliftuplift onceforfuelthe flight for subsequentis complete flight is completeMethod B:Amountoffuel remaininginFuelConsumption aircrafttanks Fuelupliftfor contained Amountofinfuel for eachFlight atblock on at the flight tanks at block onthe end of previousat end of flight flightThe fuel consumption data shall be submitted to the Director,Aircraft Engineering Directorate, Office of Director General of CivilAviation, Opp. Safdarjung Airport, New Delhi – 110003 in theprescribed format as enclosed. The data is required to be submitted onmonthly basis starting from April 2011.Sd/-(Charan Dass)1
