Flexible use of airspace to cut down on flight time, fuel consumption

Kolkata: Total radar and radio coverage along with flexible use of airspace is set to reduce travel time between Kolkata and several cities in the south by up to 10-12 minutes, leading to considerable savings in aviation turbine fuel (ATF) and carbon dioxide emission.
“Around a third of Indian airspace is controlled by military. Earlier, civilian flights were not allowed to use military airspace. Hence, air traffic control officers had to assign circuitous routes that skirted them. But now, there is greater flexibility and synergy in using these restricted airspace on a need basis. The direct routing of fights from Kolkata is saving around 9,000 kg of fuel or 28,500 kg CO2 emission everyday. That translates to 10,371
tonne of CO2 saved in a year,” said Airports Authority of India member (air navigation services) Anil Kumar Dutta on the sidelines of a seminar organised by the Air Traffic Controllers’ Guild to discuss the challenges faced by the aviation sector.
At Rs 70 per kg of ATF, that also translates in to saving of Rs 6.3 lakh in fuel cost for the airlines daily.
Sources in Kolkata ATC said flights to Chennai, Bengaluru, Hyderabad, Vizag, Bhuwaneswar, Delhi and Ahmedabad would also benefit from the flexible use of airspace that allowed direct routing of flights and also cut flight-time by 10-12 minutes. Every minute of flight reduction saves 40kg of
ATF or 126kg of CO2.
