16、he World Trade Organization Technical Barriers to Trade (TBT) Committee.13.2.1 aircraft type code, nan Aircraft Type Code (ATC) isdefined by considering both the technical considerations re-garding the design of the aircraft and the airworthiness levelestablished based upon risk-based criteria. An A

17、TC is ex-pressed as an alphanumeric character string as illustrated inFig. 1. An explanation of each character in the string isprovided below.3.2.1.1 DiscussionThe first character in the Aircraft TypeCode indicates the risk-based airworthiness level of the air-craft.(1) A “1” indicates an airworthin

27、ntrolled flight and landing, possibly using emergencyprocedures, but without requiring pilot skill beyond thatneeded to pass the Private Pilot Practical Test Standard forAirplane (refer to FAA-S-8081-14B), or requiring pilot forcesbeyond those defined in Specification F3082/F3082M. Landingmay occur

28、either at an airport or at an emergency landinglocation consistent with established emergency procedures.Some aircraft damage may be realized, either during flight orupon landing.3.2.3 development assurance level, na development assur-ance level is an indication of the level of those planned andsyst

32、 would significantly contribute to or cause one or moreserious injuries.4. Basic InformationNOTE 1Table 1 provides correlation between various Aircraft TypeCodes and the individual requirements contained within this section; referto 3.2.1. For each subsection, an indicator can be found under each AT

33、Ccharacter field; three indicators are used:An empty cell()inal applicable ATC character field columnsindicates that an aircraft must meet the requirements of that subsection.A white circle () in multiple columns indicates that the requirementsof that subsection are not applicable to an aircraft onl

34、y if all such ATCcharacter fields are applicable.A mark-out () in any of the applicable ATC character field columnsindicates that the requirements of that subsection are not applicable to anaircraft if that ATC character field is applicable.ExampleAn aircraft with anATC of 1SRLLDLN is being consider

35、ed.Since all applicable columns are empty for 4.1.1, that subsection isapplicable to the aircraft. Since the “1” airworthiness level column, the“L” stall speed column, and the “D” meteorological column for 4.1.6 allcontain white circles, then that subsection is not applicable; however, foran aircraf

36、t with an ATC of 1SRMLDLN, 4.1.6 would be applicable sincethe “M” stall speed column does not contain a white circle. Subsection4.2.1.1 would also not be applicable to the second aircraft, since itcontains an in the “M” stall speed column.NOTE 2The requirements of this chapter are applicable to all

37、systemsand equipment installed in the aircraft. These requirements are in additionto and do not supersede any additional system specific requirementsidentified elsewhere in these design standards or contained in the rules ofthe governing civil aviation authority.4.1 Function and Installation:4.1.1 E

38、ach item of installed equipment must be of a kindand design appropriate to its intended function.4.1.2 Each item of installed equipment must be marked in away that makes it clear to an installer the equipmentsidentification, function, or operating limitations, or any appli-cable combination of these

39、 factors. It is acceptable to referenceequipment installation manuals for function or limitationinformation.4.1.3 Each item of installed equipment must be installedaccording to limitations specified for that equipment.4.1.4 Each item of installed equipment must function prop-erly when installed.4.1.

40、5 The aircraft systems and equipment required for typecertification or by operating rules must be designed andinstalled so that they perform as intended under the aircraftoperating and environmental conditions.NOTE 3The intent of this requirement is to provide assurance that therequired systems and

41、equipment will function as intended in the expectedoperating and environmental conditions. It is recognized that randomfailures will occur throughout the aircraft life and that the failed devicemay no longer “perform as intended”. The acceptability of such failures orcombination of failures and thei

42、r associated risks are addressed under therequirements of 4.2.4.1.6 All aircraft systems and equipment must be designedand installed so that they do not adversely affect the safety ofthe aircraft or its occupants.TABLE 1 ATC Compliance Matrix, Section 4SectionAirworthiness LevelNumber ofEnginesType
