- Content
- This SAE Aerospace Standard (AS) defines minimum performance standards (MPS) for fuel flowmeters, fuel flow indicators, and fuel flow transmitters. The fuel flow indicators and transmitters are intended for use in 14 CFR Part 23, 25, 27, and 29 aircraft equipped with reciprocating and turbine engines. Multiple function displays are not within the scope of this SAE Aerospace Standard (refer to AS6296).
- Content
- This standard has been revised to add applicability of fuel flow flowmeters to turbine engines. The scope of the standard was adjusted to include minimum requirements for each flow rate measurement system component, which may consist of a fuel flowmeter, and a fuel flow indicator that processes the flowmeter signal and provides a reading in the cockpit. The document title was changed from Fuel Flowmeters to Fuel Flow Rate Measurement System to address the increased scope of the standard.The “Type 1 - measure rate of flow of fuel used” and “Type 2 - totalize amount of fuel consumed or remaining” definitions are no longer used since indicators may display both fuel flow parameters and the indicator requirements in this revised standard applies to both types.
