ASTM F3432-20

Standard Practice for Powerplant Instruments

SIGNIFICANCE AND USE
4.1 This practice provides designers of general aviation aeroplanes with a list of previously accepted required powerplant instruments, and a method for the powerplant information to be provided to the crew based on the type of powerplant installation. Criteria for mitigating the need for rate of change, direction of change, and proximity to limits information for some required powerplant instruments is also provided. This practice applies to reciprocating and turbine engine powerplant requirements. This practice provides a method of compliance to Section 6 of Specification F3064/F3064M.
SCOPE
1.1 This standard practice provides the minimum required powerplant instruments along with information on how that information is provided to the flight crew or pilot of Normal Category Level 1, 2, 3, or 4 aeroplanes. The material was developed through open consensus of international experts in general aviation. This practice does not consider remotely piloted aeroplanes, nor does it consider electric or hybrid-electric aeroplanes. The content may be more broadly applicable; it is the responsibility of the applicant to substantiate broader applicability as a specific means of compliance.  
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 CAAs) concerning the acceptable use and application thereof. For information on which oversight authorities have accepted this standard (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 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.  
1.4 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.
