ETSO-2C206

CIRCUIT CARD ASSEMBLY (CCA) FUNCTIONAL SENSORS USING THE AIRCRAFTBASED AUGMENTATION FOR NAVIGATION AND NON-NAVIGATION POSITION/VELOCITY/TIME (PVT) OUTPUT

1 Applicability

This ETSO provides the requirements which circuit card assembly (CCA) functional sensors using aircraft-based augmentation for navigation and non-navigation position/velocity/time (PVT) output, 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.

An ETSO-2C206 article has a limitation that requires the end-use equipment manufacturer to repeat selected detailed functional tests in the end-use equipment and complete the environmental qualification tests in RTCA document DO-316, Minimum Operational Performance Standards for Global Positioning System/Aircraft-Based Augmentation System Airborne Equipment, dated 14 April 2009 (see paragraphs 3.1.2.2 and 3.2.2 below).

This ETSO standard applies to equipment that is intended to provide PVT information for a navigation management unit application that outputs deviation commands keyed to a desired flight path, or a non-navigation application (such as automatic dependent surveillance -broadcast (ADS-B)). In navigation applications, pilots or autopilots will use the deviations output by the navigation management unit to guide the aircraft. In non-navigation applications, the PVT outputs will provide the necessary capability for the end-use equipment.

2 Procedures

2.1 General

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

2.2 Specific

None.

3 Technical Conditions

3.1 Basic

3.1.1 Minimum Performance Standard

The applicable standards are those provided for functional sensors in RTCA document DO-316, Minimum Operational Performance Standards for Global Positioning System/Aircraft-Based Augmentation System Airborne Equipment, dated 14 April 2009, Section 2.

3.1.2 Environmental Testing and Test Procedures

3.1.2.1 Environmental Testing

For the applicable environmental standards, see CS-ETSO, Subpart A, paragraph 2.1.

Nevertheless, not all types of environmental test are required for this ETSO standard, as the ETSO article for this ETSO standard is a CCA that will be later integrated into an item of ETSO equipment. Therefore, a minimal set of the environmental test conditions of EUROCAE ED14/RTCA document DO-160 has been defined (refer to Table 1) in order to verify the performance of the ETSOA article under this minimal set of conditions. The required performance under a particular environmental test is defined in the related test section in RTCA document DO-316, Minimum Operational Performance Standards for Global Positioning System/Aircraft Based Augmentation System Airborne Equipment, dated 14 April 2009, Section 2.2.

This minimal set is defined in Table 1 below. The chosen test category, associated wih the selectable parameters in the test conditions per EUROCAE ED-14/RTCA document DO-160 should be documented in the installation manual as limitations for the installation.

The test sections that are identified as optional are not required for an ETSO-2C206 application. Nevertheless, the ETSO CCA article can be subjected to these test conditions by the applicant on a voluntary basis. When optional sections are not tested, they shall be marked with 'X' in the environmental testing summary.

3.1.2.2 Environmental Test Procedures for End User

The end user of this ETSO article will be required to complete the environmental qualification testing after integration of the ETSO2C206 CCA. In order to allow the end user to properly test the functionality of the CCA functional sensor in environmental conditions, the applicant for a 'CCA functional sensor' shall provide the detailed functional test procedures to evaluate the required performance of the CCA functional sensor in compliance with RTCA document DO-316, Minimum Operational Performance Standards for

- 3.1.3 Software

See CS-ETSO, Subpart A, paragraph 2.2.

3.1.4 Airborne Electronic Hardware

See CS-ETSO, Subpart A, paragraph 2.3.

3.2 -Specific

3.2.1 Failure Condition Classification

See CS-ETSO, Subpart A, paragraph 2.4.

A failure of the function defined in paragraph 3.1.1 of this ETSO is a:

- -major failure condition for a malfunction of oceanic/remote, en route, terminal navigation and lateral navigation (LNAV) approaches; - -minor failure condition for a loss of navigation in oceanic/remote, en route, terminal navigation and lateral navigation (LNAV) approaches.

3.2.2 Additional Specific

Barometric-aiding fault detection and exclusion (FDE)

If the CCA functional sensor uses barometric-aiding to enhance the availability of FDE, then the equipment shall meet the requirements in RTCA document DO-316, Appendix G.

The applicant shall provide to the end user the detailed functional test procedures of the CCA functional sensor for the end user to complete the environmental testing.

The intended installation environment and the associated installation constraints should be documented in the installation manual.

Limitations

The following specific limitations shall be documented in the installation manual and in the declaration of design and performance (DDP) of the CCA functional sensor:

- -'The manufacturer of the end -use equipment, using the <insert equipment model> CCA functional sensor, is required to perform the testing described in ETSO-C196<latest revision> Appendix 1 with the CCA functional sensor installed in the enduse equipment.' - -'The manufacturer of end -use equipment is required to complete full environmental qualification at the enduse equipment level.'
