Air traffic

Air pollution – emissionsGreenhouse gases

Carbon dioxide (CO2)

Nitrogen oxides (NOx)

Water vapor (H2O)

Methane (CH4) Carbon monoxide (CO)

Air traffic

Air pollution – emissions

5

Air traffic

Noise pollution In the air / on the groundEngines

Jet engines – 140 dB Turboprop engines – 130 dB Piston engines – 120 dB

Auxiliary systems Air-conditioning system, heating system,

pressurization, other energy sourcesSupersonic explosion

6

Air traffic

Noise pollutionFactors influencing noise propagation:

Air relative humidity Air temperature Direction and wind speed Atmospheric turbulence Ground surface (nature and artificial obstacles) Distance from the source

Air traffic

Noise pollution

8

Air traffic

How can we reduce noise?Passive reduction

Influence of terrain Influence of vegetation (trees)

Active reduction Design of sources Engine position Higher angle of climb RWY in use (night restriction) Noise reduction during approach Air route design

Airports

EmissionsAircraft, cars, trucks, public transport

Noise pollutionAircraft, cars, trucks, public transport

Leak → underground water pollutionFuel, service liquids Icing, anti-icing procedures
