Abstract

This specification provides international standards for ice protection aspects of airworthiness and design for ”general aviation” aircraft. The applicant for a design approval must seek the individual guidance of their respective civil aviation authority (CAA) body concerning the use of this standard as part of a certification plan.

The standards cover: types of aircraft operational requirements; crew external visibility (windshields and windows); ice shedding (engine inlet ice ingestion, propeller ice shedding, airframe ice shedding, ice protection system failure considerations); engine installation and induction system ice protection (propellers, turbine engines in flight, turbine engines on ground).

Also addressed in this specification are instrumentation ice protection, flight into icing conditions, aircraft not approved for flight in icing, and atmospheric icing conditions.

Scope

1.1 This specification covers international standards for ice protection aspects of airworthiness and design for “general aviation” aircraft.

1.2 The applicant for a design approval must seek the individual guidance of their respective civil aviation authority (CAA) body concerning the use of this specification as part of a certification plan. For information on which CAA regulatory bodies have accepted this specification (in whole or in part) as a means of compliance to their Small Aircraft Airworthiness regulations (hereinafter referred to as “the Rules”), refer to ASTM F44 webpage (www.ASTM.org/COMMITTEE/F44.htm) which includes CAA website links.

1.3 Units—The values are stated in units common to the field of aircraft icing. Typically SI or inch-pound units are used, but in some cases this has resulted in the use of mixed units due to the historical development of these values. In cases where values are given in one system with the other system following in brackets, the values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.4 This standard 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 standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
