Commercial aircraft depend on accurate measurement, dependable control, and consistent performance over long service lives. Simmonds Precision Products supports commercial aviation with fuel measurement systems, proximity sensing, and electronics that help aircraft operate safely and reliably across the globe.
Proven on widely used platforms
Simmonds has supported major commercial aircraft programs across Boeing and Airbus families, reflecting a long-standing commitment to quality and consistency in high-volume aerospace production and sustainment.
Fuel measurement systems
Simmonds supports commercial fuel gauging and fuel measurement systems through components and electronics that enable accurate fuel quantity measurement and indication, including:
- Door and hatch indication (confirming open, closed, and latched states)
- Landing gear position sensing and indication
- Weight-on-wheels indication
- Spoiler position indication
Aircraft electronics and data concentration
Many commercial 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:
- Signal aggregation and conditioning
- Data formatting and distribution
- Indication and control outputs
- Embedded electronics expertise
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.
