ETSO-C196b

AIRBORNE SUPPLEMENTAL NAVIGATION SENSORS FOR GLOBAL POSITIONING SYSTEM EQUIPMENT USING AIRCRAFT-BASED AUGMENTATION

1 Applicability

This ETSO provides the requirements which airborne supplemental navigation sensors for Global Positioning System equipment using aircraft-based augmentation that are designed and manufactured on or after the date of this ETSO must meet in order to be identified with the applicable ETSO marking.

Note: Revision b provides applicants with the option to use an ETSO-2C206 GNSS circuit card assembly (CCA) as part of their ETSO application. There is no technical change to the MOPS in comparison with ETSO-C196a.

2 Procedures

2.1 General

The applicable procedures are detailed in CS-ETSO, Subpart A.

2.2 Specific

This section applies only for ETSO articles that use an ETSO-2C206 GNSS CCA.

Applicants who use an ETSO-2C206 GNSS CCA will need to coordinate with their GNSS CCA supplier for at least the following aspects:

2.2.1 Access to the Information of the Selected ETSO-2C206 CCA

The applicant is responsible for establishing the necessary communication channels with the ETSO-2C206 holder company. Applicants who use an ETSO2C206 SBAS CCA will need to coordinate with their SBAS CCA supplier to obtain the documentation that supports ETSO-2C206.

The applicant's organisation shall establish a means of communication to obtain timely notifications of design changes, open problem reports (at least the ones that impact the usage of the CCA), occurrence reports and airworthiness directives that affect or relate to the ETSO-2C206 article.

2.2.2 Assessment of Design Changes

The applicant shall perform an impact analysis of the design changes to the ETSO2C206 article, and shall perform the necessary development life-cycle activities that are impacted by the ETSO-2C206 changes.

Note: If a major change (as assessed per point 21.A.611) is applied to the ETSO2C206 article, which is installed in the ETSO-C196b article, it is also systematically considered to be major for the ETSO-C196b function.

2.2.3 Assessment and Reporting of Open Problem Reports (OPRs)

The applicant shall perform the assessment of the ETSO-2C206 CCA OPRs. The applicant shall report the resulting OPRs that affect the ETSO-C196b article.

3 Technical Conditions

3.1 Basic

3.1.1 Minimum Performance Standard

The applicable standards are those provided in the Radio Technical Commission for Aeronautics (RTCA) document DO-316, Minimum Operational Performance Standards (MOPS) for Global Positioning System/Aircraft Based Augmentation System Airborne Equipment, dated 14 April 2009, Section 2.
