Workforce and work environment Environmental and climate protection Financial review Sustainable DevelopmentGlossaryAirport campusThe term airport campus is used to refer collectivelyto the entire airport site, including all of its buildingsand facilities.Airports Council International (ACI)An international organization, headquartered in Geneva,which represents airport operators. More than1,600 airports in almost all of the world’s countriesare ACI members, including 400 airports in 46 Europeancountries.Air source technologyAir source technology uses a system of natural ventilation.With natural ventilation, fresh air enters a buildingthrough vents and openings. Interior heat sourcesdeter mine the pattern of airflow within rooms.Auxiliary power unit (APU)Today’s commercial aircraft have an auxiliary powerunit in addition to their two or four main engines. TheAPU is used to start the main engines and to generateelectric power when the plane is on the ground.BiodiversityBiodiversity refers to the variety of life forms (includinganimal species, plants, fungi and bacteria), thehabitats in which these life forms live (ecosystemssuch as woodland or bodies of water), and the geneticdiversity within species (e.g., subspecies, strains andbreeds).BiomassBiomass is biological material that is biogenic asopposed to fossil in origin. Biomass refers both toliving and naturally growing material in nature and towaste matter resulting from that material.Carbon dioxide (CO 2 )Carbon dioxide is a colorless, odorless gas that is createdwhen substances containing carbon combust(e.g., to generate heat and electricity or to power air -craft and motor vehicles). Carbon dioxide absorbspart of the heat radiation in the earth’s atmosphere.This property makes it a so-called greenhouse gas.Carbon monoxide (CO)Carbon monoxide is a colorless, odorless and flavor -less toxic gas. It is created through the partial combustionof substances containing carbon withoutsufficient oxygen present or through combustion atvery high temperatures.CargoA load carried on a means of transport, generally for afee. The term cargo is applied to air freight and mail.Cash flow from operationsCash flow is a business metric describing the newnet cash assets during an accounting period.Collaborative Decision Making (CDM)Airport CDM is an approach designed to streamlinecollaboration between all parties involved in flightand handling operations (airports, airlines, groundhandling operators and air traffic control) so as to optimizeprocedures and maximize resource efficiency.Continuous Descent Approach (CDA)An approach method using reduced engine power.The aircraft approaches its destination airport in asteady descent. This helps to conserve fuel andreduce aviation noise.Decibel (dB)A unit of measure for sound intensity and sound pres -sure. One decibel (dB) is the smallest change involume that a human can register. The decibel scaleis logarithmic. Thus, a change of 10 dB represents ahalving or doubling in the perceived noise level.DeicingAircraft deicing is an operation carried out on planesbefore they depart in order to clear them of ice andsnow. In winter weather conditions, crucial parts ofaircraft must be protected to prevent ice re-forming.This is accomplished by spraying them with a mixtureof water and deicing agent (glycols).181
