New Practice for Aircraft Turbine Fuel System Fuel Icing
1. Scope
The objective is to define test criteria that verify the fuel system's ability to provide uninterrupted fuel flow and pressure throughout its operational range when exposed to water-saturated fuel and cooled to conditions likely to cause ice formation. These criteria are established to support compliance with § 23.2430(a)(3) and ASTM F3063 section 4.1.2
Keywords
general aviation; aircraft; turbine; icing; powerplant
Rationale
Despite the existence of such requirements, there remains a lack of clear industry guidance regarding acceptable methods of compliance, particularly with respect to fuel system performance when exposed to water contamination and conditions associated with the formation of ice on aircraft components. Key aspects such as water dropout mechanisms, ice accretion, and the release of ice into the engine feed system are not yet fully characterized, potentially leading to flow restrictions, power loss, or flameout events. Providing clear guidance would help standardize compliance approaches and improve safety assurance.
The title and scope are in draft form and are under development within this ASTM Committee.
