ASTM F3064/F3064M-24 PDF

Overview

ASTM F3064/F3064M-24 – Standard Specification for Aircraft Powerplant Control, Operation, and Indication establishes the minimum requirements for the control systems, operational characteristics, and indication of propulsion systems installed on aeroplanes. Developed by ASTM Committee F44, this international standard guides design approval applicants in achieving compliance with civil aviation airworthiness regulations for powerplant systems. While its primary focus is on aeroplanes, the specification’s content may also be relevant for other propulsion system applications. This standard aligns with internationally recognized standardization principles and serves as a valuable reference in aircraft certification plans.

Key Topics

• Powerplant Control Requirements:

  • Ensures controls are properly located, arranged, and secured, minimising inadvertent movement and preventing unsafe operation.
  • Details redundancy considerations and fire-resistance requirements for critical controls.

• Indication Systems:

  • Specifies requirements for the reliable measurement and display of essential powerplant parameters (e.g., fuel, oil quantity, temperature, and pressure).
  • Covers installation and calibration practices for both analog and digital displays to support clear pilot awareness.

• Operational Characteristics:

  • Requires thorough evaluation of both normal and emergency operating conditions, such as engine starting/stopping, cooling, and response to negative acceleration.
  • Addresses operational limitations, fuel type and grade, temperature ranges, and compatibility with auxiliary systems like APR (Automatic Power Reserve).

• Electronic Engine Control and Safety:

  • Outlines expectations for electronic engine control system integrity, high-intensity radiated field (HIRF) and lightning resilience, and prevention of loss-of-thrust/control (LOTC/LOPC) events.
  • Calls for comprehensive safety assessments and compliance with applicable regulatory guidance (e.g., FAA and EASA standards).

• Compliance Mapping:

  • Provides correlation tables and annexes mapping requirements to EASA CS-23 and FAA 14 CFR Part 23, facilitating regulatory acceptance and streamlined certification.

Applications

ASTM F3064/F3064M-24 is utilized by:

• Aircraft Designers & Manufacturers: Assisting in the design, validation, and certification of powerplant controls and indication systems for aeroplanes, including engine control levers, mixture controls, and engine status indicators.
