Which document issue applies to the references cited in the ETSO-C16b Appendix 1 Minimum Performance Standard for Electrically Heated Pitot and Pitot-Static Tubes?

The applicable issue of cited publications shall be the issue in effect on the date of the publication of this document, unless otherwise specified.

What design features must a probe include to prevent mis-installation on the aircraft?

The probe shall incorporate design features to minimise the potential for mis-installation, for example, different pneumatic fitting sizes or types, or different electrical connector keying, when the probe contains multiple pneumatic or electrical connections.

What is the requirement for drain holes in a pitot probe regarding liquid particle separation?

There shall be at least one drain hole to discharge or scavenge entrained liquid, such as rain or melted ice water.

How must protective coatings and finishes on a probe perform under qualification testing?

Protective coatings and finishes shall not crack, chip, or scale to the extent that the probe no longer meets the aerodynamic accuracy requirements when exposed to the qualification test requirements of this standard.

What is the compliance demonstration rule for Section 4.6 of the ETSO-C16b Appendix 1 standard?

Other means can be used to demonstrate compliance with this requirement provided there is evidence they are equivalent or better than the specified test. Such alternate means is considered a deviation.

Which fire and flammability test standard applies to non-metallic probes under ETSO-C16b Appendix 1?

Non-metallic probes shall be tested for compliance with the fire and flammability test standards specified in EUROCAE ED-14G / RTCA DO-160G, Section 26, Category C.

What is the flame propagation requirement for non-metallic probes in the fire test?

If ignition occurs inside or outside of the equipment, the probe shall not propagate the flame.

Are fire and flammability tests required for metallic probes under ETSO-C16b Appendix 1?

Tests are not required for metallic probes.

What happens if there is a conflict between the text of the ETSO-C16b Appendix 1 document and the references cited therein?

In the event of conflict between the text of this document and the references cited herein, the text of this document takes precedence.

What must the probe design consider regarding ingested solid particles?

The probe design shall consider the effects of ingested solid particles such as ice, sand and dust.

Appendix 1 to ETSO-C16b – Minimum Performance Standard for Electrically Heated Pitot and Pitot-Static Tubes

ED Decision 2018/002/R

This ETSO modifies SAE AS8006, as follows:

AS8006A Section	EASA Modification
2.1	Page 1, Replace Subsection 2.1, with the following text: 2.1 Applicable Documents The following publications form a part of this document to the extent specified herein. The applicable issue of cited publications shall be the issue in effect on the date of the publication of this document, unless otherwise specified. In the event of conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific deviation or exemption has been obtained.
3.4.2	Page 3, replace Subsection 3.4.2 with the following text: 3.4.2 Particle Separation Features The probe shall be designed with baffling or a pitot settling chamber, or both, to minimise the entry of liquid or solid particles into the tubing connecting the probe to the aircraft instruments. There shall be at least one drain hole to discharge or scavenge entrained liquid, such as rain or melted ice water. The probe design shall consider the effects of ingested solid particles such as ice, sand and dust.
3.4.3	Page 3, replace Subsection 3.4.3 with the following text: 3.4.3 Mis-installation The probe shall incorporate design features to minimise the potential for mis-installation on the aircraft. For example, in the case where the probe contains multiple pneumatic or electrical connections these features may include the incorporation of different pneumatic fitting sizes or types, or different electrical connector keying.

3.4.11	Page 4, amend 3.4.11 as follows: Protective coatings and finishes utilised in the construction of the probe shall not crack, chip, or scale to the extent that the probe no longer meets the aerodynamic accuracy requirements when exposed to the qualification test requirements of this standard. Other FAA modification not retained.
4.6	Page 7, amend 4.6 as follows: Other means can be used to demonstrate compliance with this requirement provided there is evidence they are equivalent or better than the specified test. Such alternate means is considered a deviation.
5.26	Page 12, replace Subsection 5.26 with the following text: 5.26 Fire, flammability Non-metallic probes shall be tested for compliance with the fire and flammability test standards specified in EUROCAE ED-14G / RTCA DO-160G, Section 26, Category C. If ignition occurs inside or outside of the equipment, the probe shall not propagate the flame. Tests are not required for metallic probes.
