| description abstract | 4.1 This practice proposes considerations and methods of compliance for precipitation effects for Specification F3117/F3117M, Pilot Compartment View. 4.2 Plexiglass windows inherently provide an acceptable pilot view in case of precipitation in non-icing conditions without a coating and are not subject to the requirements of this practice. For novel configurations such as glass windshields with neither hydrophobic coatings nor traditional precipitations protection methods, applicants must discuss their means of compliance with their certification authority. 4.3 Specific types of protection means have additional considerations related to maintenance and continued operational safety. 4.4 The requirements herein are organized such that an Applicant can identify the specific sections that apply to their design implementation. Any other sections can be identified by the Applicant as “Not Applicable.” | |

| scope | 1.1 This practice provides definitions and guidance for how an applicant can show compliance to the requirements that the pilot view must allow the flight crew to perform their duties in case of precipitation effects on the pilot view. This includes definition of potential environments and considerations for specific types of protections. 1.2 An applicant intending to propose this information as Means of Compliance for a design approval must seek guidance from their respective oversight authority (for example, published guidance from applicable CAA) concerning the acceptable use and application thereof. For information on which oversight authorities have accepted this practice (in whole or in part) as an acceptable Means of Compliance to their regulatory requirements (hereinafter “the Rules”), refer to the ASTM Committee F44 web page (www.astm.org/COMMITTEE/F44.htm). 1.3 Units—This practice may present information in SI units, English Engineering units or both; the values stated in each system may not be exact equivalents. Each system shall be used independently of the other; combining values from the two systems may result in nonconformance with the standard. 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. | |
