Fuel Metering Unit (FMU)
Aero Engine Controls provides a range of solutions, from the more traditional complex hydro-mechanical systems still used on some turboprop applications to electronically controlled units. While traditional electronically controlled units have no embedded electronics, our latest units incorporate the patented electronic SmartCalTM technology to improve accuracy and reduce build and through-life costs.
The newly launched design philosophy enhances our capabilities with:
- Simplicity of construction
- Compatibility with new manufacturing techniques
- Smart calibration
- Secure high-quality supply chain
This ensures that we can deliver products you can trust.

Fuel Pump Metering Unit (FPMU)
This FPMU is a low-cost failed fixed system designed for the engine on a military turboprop.
The FPMU incorporates built-in SmartCalTM electronic calibration data, which increases overall metering accuracy and reduces lane-to-lane error in a more cost effective manner than ever before.

Our latest fuel metering unit on the Rolls-Royce Trent 1000 engine uses SmartCalTM with built-in electronic calibration data for increased overall metering accuracy and reduced lane-to-lane error.
The Rolls-Royce Trent 1000 unit also incorporates part of the innovative FLOWlinxTM system, reducing pump-heat rejection by 40% and minimizing the need for additional cooling.
