Emissions have been a controversial subject CO2 emission are directly related to fuel

consumption (1 kg fuel = 3,15 kg CO2)

Reasons for fuel burn reduction:

Environmental Boundaries (ETS) Scarcity of oil


Oil use – “A flame in the darkness”


Aviation industry growth expectations:

Airbus: 4,9% passenger growth/year until 2025 Boeing: 4,5% passenger growth/year until 2026

Source: Eurocontrol


More passengers, improved efficiency: Technological improvements

How to achieve fuel reduction on short term?

Adjust current operational procedures!

Can it be more efficient?

Yes it can!


Weather conditions not taken into account Standard flight operation

Towing aircraft to the runway Reduce time engines running before take-

off

According to Virgin: 120.000 tonnes

Downturns:◦ Only applicable on relative small fleets◦ Not applicable on every airport


Short Haul Long HaulReduction (%) 3,2 %* 0,22 %*

Fuel (kg) 60 kg 200 kgCO2 (kg) 189 kg 630 kg

* Based on 30 minutes APU use** Based on 60 minutes APU use

GPU use instead of APU use

Side effects:◦ INCREASE OF OPERATIONAL COSTS◦ A GPU also burns fuel


Short Haul Long HaulReduction (%) 2,42 % 0,11 %


* Based on 12 minutes taxi time (8 minutes with one engine out)

ONE ENGINE-OUT TAXI

Side effects:◦ NOT APPLICABLE ON SHORT TAXI TIMES◦ INCREASE OF MAINTENANCE COSTS




Note: use of flap setting 2 instead of 3

TAKE-OFF CONFIGURATION

Side effects:◦ LONGER RUNWAY TAKE-OFF LENGTH REQUIRED


Short Haul Long HaulReduction (%) 0 % 0,93 %

Note: decrease cruise speed with 16 kts

CHANGE IN CRUISE SPEED

Side effects:◦ LONGER FLIGHT TIME (AMS-HKG = 24 MIN.)


Short Haul Long HaulReduction (%) 0 % 8,53 %

Fuel (kg) 0 kg 7763 kgCO2 (kg) 0 kg 24.453 kg

* Optimum altitude compared to the cross-over altitude

Altitude Selection

Side effects:◦ LONGER FLIGHT TIME

Note: actual flightplan compared to greatcirkel distance

Route Selection

Side effects:◦ TOTAL FLIGHT SYSTEM RENEWABLE
