Electrically Heated Pitot and Pitot-Static Tubes

1 Applicability

This ETSO provides the requirements which electrically heated pitot and pitot-static tubes, heated by aircraft electrical power, 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.

2 Procedures

2.1 General

Applicable procedures are detailed in CS-ETSO Subpart A.

2.2 Specific

2.2.1 Test Report

The test report identified in Section 2.4.2 and data identified in Chapter 4 of EUROCAE ED-225, Ice and Rain Minimum Qualification Standards for Pitot and Pitot-Static Probes, shall be provided to the installer to support installation approval.

2.2.2 Rated Performance Documentation

The rated performance to be declared in the declaration of design and performance (DDP) shall at least contain:

— the probe type and class;

— the passed test conditions;

— the concentration factors used for icing tests; and

— the probe test voltage

3 Technical Conditions

3.1 Basic

3.1.1 Minimum Performance Standard

Standards set forth in SAE International’s Aerospace Standard AS8006A, Minimum Performance Standard for Pitot and Pitot-Static Tubes, revised August 2015, as Modified in Appendix 1 of this ETSO, and EUROCAE ED-225, Ice and Rain Minimum Qualification Standards for Pitot and Pitot-Static Probes, issued February 2016, as modified in Appendix 2 of this ETSO.

Note: The electric heater function is defined as starting with the aircraft interface (connector). The pneumatic pressure function is defined as starting with the pressure transducer interface if it is integrated with the probe or starting with the aircraft interface if the pressure transducer is separated from the probe.
