Which stage of the flight consumes more fuel?

¿CuáDo you think it is the stage of flight that Iás combustible consume? Today we are going to review an interesting análysis carried out by the consulting firm OAG.

Combustible, key piece of the puzzle that allows aviationón move in the world generating employment, commerce and moving the economyíto the regions, but there is a battle on the part of the industry: do the aviationón más sustainable and green.

At this point it is that the manufacturers and aerolícompanies work hard to make the industry moreás efficient for example optimizing descents and advance the use of sustainable fuels, for instance.

The stage of flight that más combustible consume

Searching for optimizationón and reductionón of the carbon footprint is that the question arises, ¿thaté stage consumes más combustible? This focused on reductionón of this consumption to in turn, reduce CO2 emissions in industry.

Analyzing hundreds of data and informationónumber of flights, AOG has been able to determine the stages with the highest fuel consumption, ¿to beá the takeoff, where m is appliedás power to the engines the stage with the highest consumption? Let's see:

The 28 of January of 2022, AOG analysisó several flights from London Heathrow Airport (LHR) to a variety of destinations, using different aircraft, operated by different airlinesílines and different flight durations. The flight más short was the Air France flight to Charles de Gaulle airport in Parisís (CDG) in a grandfatherón A319, a solo flight 348 km and a durationón planned one hour and 20 door to door minutes. The flight máIt's a long Cathay Pacific flight to Hong Kong (HKG) using an A350, a flight of 12 hours and 5.500 km.

The other flights went to Athens (ATH), Dubái (DXB), Edinburgh (EDI), Ginebra (GVA), Helsinki (HEL), Lisboa (LIS), Madrid (MAD) and new york (JFK).

The model divides fuel consumption into six stages of flight: exit shoot, takeoff, ascent, cruise, approximationón and entry taxi. East á Of course, how mucháhow short is the flight, más, proportionally, non-cruise elements of the flight contribute. to total fuel use, but you can't escape the fact that on every flight, no matter the distance, the fuel used to take off is a fractionón relatively smallña of total fuel use.

For the flight más largo, a Hong Kong, the cruise consumes the 96% of total fuel burned. For the flight to Dubáand it's almost the same, since the 95% of fuel consumption is done simply while cruising. At the other end of the scale, cruise ships represent only the 62% of total fuel consumption for the flight to París and the 68 % for the flight to Edinburgh.

Obviously, there are más in fuel consumption than simply durationón of a flight, as shown in the gráI stay previous. Among the flights analyzed, It's Dub's flightái -not the flight más largo a Hong Kong- the one who consumes más combustible. Once againón is that the flight of DubáIf you operate with an A380 that, with a weight mátakeoff time (MTOW) from 575 tons, is significantly más heavier than the 777 to JFK and maybeáIt's twice as much as the A350 at HKG. Of course, spaghettién leva más passengers.

Finally and surprisingly, fuel consumption data shows that between the 2% and the 17% of fuel consumption goes to taxiing activities, which proportionally represents más fuel consumption on flights máshort s. It's not extrañar than many aerosolíairlines and airports use tugboats to move planes instead of burning kerosene unnecessarily whileún isán on land.

¿They expected this result from the yearálysis?
