Rotorcraft operate in high-vibration, high-utilization environments where aircraft availability depends on reliable precision systems and maintainable design. Simmonds Precision Products supports rotorcraft platforms with fuel measurement systems, fuel gauging systems, health monitoring, and rugged actuation.
Proven on widely used rotorcraft platforms
Simmonds has a long track record supporting rotorcraft fleets where readiness and sustainment matter. Our experience spans both military and commercial rotary wing applications.

Fuel measurement systems
Accurate fuel measurement supports flight planning, safety, and mission execution. Simmonds supports rotorcraft fuel gauging and fuel measurement systems through components and electronics that enable reliable sensing and indication, including:
- Fuel probes and sensing assemblies used in fuel gauging systems
- Electronics that process sensor inputs and report fuel quantity information
- System components that support maintainers with dependable indication and diagnostics
Health monitoring for readiness
Rotorcraft operators rely on health monitoring to reduce unscheduled maintenance and keep aircraft available. Simmonds supports health monitoring capabilities that help operators:
- Detect issues earlier through condition-based monitoring approaches
- Plan maintenance with better insight
- Keep fleet data current and actionable
Actuation for flight-critical functions
Simmonds supports electro-mechanical actuation used in rotorcraft systems where performance and reliability are essential, including:
- Actuation built for demanding vibration and duty-cycle profiles
- Systems designed and tested to perform under mechanical load
- Support for production and sustainment needs across program lifecycles
Aircraft electronics and data concentration
Many rotorcraft applications require electronics that aggregate signals, format data, and deliver trusted outputs across the aircraft.
Simmonds supports these needs with electronics and assemblies that integrate sensing inputs and produce actionable outputs for indication and control, including:
- Aggregating and conditioning sensor inputs
- Formatting and distributing data for downstream systems
- Producing indication and control outputs
- Building microprocessor-based embedded electronics for demanding aerospace environments

Testing, screening, and verification
Rigorous verification is part of who we are. Simmonds teams support production and sustainment through function testing, and through Environmental Stress Screening (ESS) and Highly Accelerated Stress Screening (HASS) practices used to identify defects early and reduce risk in the field. Better quality processes create better aircraft systems, primed for precision performance any time, anywhere.
