ICS 49 is a classification code in the International Classification for Standards (ICS) system. It covers "AIRCRAFT AND SPACE VEHICLE ENGINEERING". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 10405 standards classified under ICS 49 (AIRCRAFT AND SPACE VEHICLE ENGINEERING). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

This document specifies common fundamental concepts for long term archiving and retrieval of mechanical CAD information for elementary parts and assemblies. It details the “fundamentals and concepts” of EN 9300-003:2012 in the specific context of long-term archiving of CAD mechanical models.
Mechanical CAD information is divided into assembly structure and geometrical information, both including explicit and implicit geometrical representation, geometric dimensioning and tolerancing with form features.
The EN 9300-1XX series is organized as a sequence of parts, each building on the previous ones in a consistent way, each adding a level of complexity in the CAD data model. This includes the detailing of relationships between the essential information for the different types of CAD information covered by the EN 9300-1XX series.
As technology matures, additional parts will be released in order to support new requirements within the aerospace community.

This document provides means to demonstrate compliance with:
— the “geo-awareness” requirements specified in Part 2 points (13), Part 3 points (15) and Part 4 points (10) of the Commission Delegated Regulation (EU) 2019/945; and to
— the requirement on the smooth interaction of the optional geofencing function with the flight control system of the UA set by Part 2 points (14), Part 3 points (16) and Part 4 points (11) on the optional geofencing function.
This document specifies the minimum performance required from this “geo-awareness” function, without prescribing its design and implementation as far as possible.
Compliance with this document is recommended as one means of assuring that the geo-awareness function will perform its intended sub-functions satisfactorily under all conditions normally encountered in routine aeronautical operation.
Compliance to the “smooth interaction” requirement is, for a large part, addressed by 6.3 on safe controllability of EN 4709-001:2026. This document will therefore refer to it to a large extend.
NOTE In this document, we will use “function” to designate the objects of this specification, and “equipment” to identify the entity implementing this function in whatever form.

1.1 This document is intended to be used to assign part classifications across the aviation industries that use AM to produce parts.
1.2 This document is applicable to all AM technologies defined in ISO/ASTM 52900 used in aviation.
1.3 This document is intended to be used to establish a metric for AM parts in downstream documents.
1.4 This document is not intended to establish criteria for any downstream processes, but rather to establish a metric that these processes can use.
1.5 The part classification metric could be utilized by the engineering, procurement, non-destructive inspection, testing, qualification, or certification processes used for AM aviation parts.
1.6 The classification scheme in this document establishes a consistent methodology to define and communicate the consequence of failure associated with AM aviation parts.
1.7 This document is not intended to supersede the requirements and definitions of the applicable regulations or policies, including but not limited to the ones listed in Annex A1.
1.8 Tables A.1.1-A.1.3 align the existing regulations and guidance with the four part classes established herein. However, this alignment should not be construed as an alignment of the existing regulations to each other.
1.9 The material or process, or both, in general does not affect the consequence of failure of a part, therefore the classification scheme defined in this document may be used outside AM.
1.10 The user of this document should not assume regulators’ endorsement of this document as accepted mean of compliance.
1.11 This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this document to establish appropriate safety, health, and environmental documents and determine the applicability of regulatory limitations prior to use.
