13、 4618:2009 (E) 4 Introduction This standard has been prepared in order to specify requirements and determination methods for newly certificated commercial passenger aircraft programmes. It may also apply to current production aircraft, should it be shown to be technically feasible and economically j
14、ustifiable. The standard distinguishes between safety, health and comfort conditions for passengers and crew under a variety of phases of flight, including embarkation and disembarkation. The standard is intended for use in design, manufacturing, maintenance and normal operation of commercial aircra
15、ft. The standard committee has tried to make the standard performance based. This means that only parameters of direct effect on safety, health and comfort of aircraft occupants are considered. Prescriptive design solutions, such as ventilation flow rates, are not described in the clauses of the sta
16、ndard. Nevertheless, in exceptional cases, current technology is used in notes, appendices and/or recommendations to describe available solutions that may meet the objectives of individual requirements of the standard. Regulatory bodies may apply this standard or parts thereof. EN 4618:2009 (E) 5 1
17、Scope This standard specifies requirements and determination methods for newly certificated commercial passenger aircraft programmes. This standard applies to newly certificated commercial passenger aircraft programmes. It may also apply to current production aircraft if it does not carry significan
18、t penalties, i.e. if it can be shown to be technically feasible and economically justifiable. This standard covers the period from first crew embarkation to last crew disembarkation. NOTE 1 During embarkation and disembarkation, reduced temperatures in the cabin may be desirable due to increased met
19、abolic activity of the occupants. In some ground cases, the aircraft environmental control system (ECS) may not be able to compensate for the external conditions influencing the cabin comfort conditions, such as open doors, extreme hot/cold ground/air temperatures or radiant heat. In this case, exte
20、rnal air-conditioning systems, for example conditioned low-pressure ground air or high-pressure supply, may be used to supplement the aircraft ECS. If the temperature range stated in this standard is regularly exceeded (either above or below the stated range), changes to airline and/or airport proce
21、dures and/or aircraft design should be introduced. NOTE 2 During ground operations, the external air quality may adversely influence the air quality within the aircraft cabin. Contamination produced as a result of servicing activities or ground operations vehicles may enter the aircraft directly, fo
22、r example via open doors, and the ECS may not be able to effectively control contaminant levels in the cabin. Airline and airport operational procedures should be organised so as to avoid direct contamination of the cabin from these pollutant sources. If the contaminant ranges stated in this standar
23、d are regularly exceeded, changes to airline and/or airport procedures and/or aircraft design should be introduced. Outside air quality levels would usually be regulated by national authorities. The population under consideration passengers and crew excludes individuals with pre-existing infirmity o
24、r ill health conditions. All values given in this document are sea-level equivalent (see Clause 4). According to the Air Quality Guidelines WHO 1999, paragraph 2.2.3, For gaseous pollutants, no increase in effects over those experienced at sea level would be expected as a result of the increase of t
