The global electric aircraft onboard sensors market is entering a high-growth phase as electrification reshapes the future of aviation propulsion, safety systems, and aircraft certification frameworks. Valued at USD 0.5 billion in 2025, the market is projected to reach USD 1.1 billion by 2035, registering a CAGR of 8.3% over the assessment period. This expansion represents an absolute value increase of USD 628.2 million, with the market expected to grow by nearly 2.2 times during the forecast horizon. Growth is being driven by rising investments in electric and hybrid-electric aircraft programs, increasing regulatory focus on sustainable aviation, and the critical role sensors play in enabling safe, certifiable electric flight operations.
Electric aviation marks a fundamental shift away from combustion-based propulsion toward battery-powered and hybrid-electric architectures, significantly increasing reliance on advanced sensing technologies. Unlike conventional aircraft, electric platforms require continuous real-time monitoring of energy storage, power distribution, and motor performance to ensure operational safety and efficiency.

Key sensing requirements emerging from electric propulsion architectures include:
- Continuous battery temperature and thermal gradient monitoring to prevent thermal runaway
- Precise torque, speed, and vibration sensing for electric motor efficiency optimization
- Real-time voltage and current monitoring across power distribution networks
- Integrated health monitoring systems to support predictive maintenance and certification compliance
As a result, onboard sensors have evolved from auxiliary components into mission-critical systems at the heart of electric aircraft design.
Market momentum is accelerating across multiple aviation segments, including urban air mobility (UAM), regional electric aircraft, and general aviation training platforms. Urban air mobility vehicles, many of which operate in autonomous or semi-autonomous configurations, depend heavily on sensor reliability for flight stability, passenger safety, and regulatory approval. Regional electric aircraft programs targeting short-haul routes under 500 miles require sensor networks capable of validating propulsion performance throughout extensive flight-test and certification cycles. Meanwhile, electric training aircraft are increasingly adopted to reduce operating costs and emissions, driving demand for sensors that extend component lifespan and enable condition-based maintenance.
Application-driven adoption is supported by:
- Growing UAM pilot programs in densely populated metropolitan regions
- OEM-led development of 50–100 seat electric regional aircraft
- Electrification of flight training fleets seeking lower lifecycle costs
- Rising demand for real-time diagnostics in early-stage aircraft platforms
Regulatory frameworks are playing a decisive role in shaping market demand. Aviation authorities worldwide are introducing new certification pathways for electric aircraft, with onboard sensors serving as primary data sources for airworthiness validation. Sensor-generated datasets underpin propulsion system validation, safety case development, and operational envelope definition, making data accuracy and reliability essential to commercialization timelines.
Certification-driven demand is reinforced by:
- Mandatory real-time health monitoring requirements
- Increased scrutiny of battery safety and thermal management systems
- Expanded use of sensor data in flight-test campaigns
- Dependence on sensor reliability to shorten certification timelines
Government-backed sustainable aviation initiatives further strengthen the market outlook. China’s Made in China 2025 program, NASA’s electric aviation research initiatives, and European Union sustainability mandates are collectively accelerating electric aircraft development while simultaneously supporting domestic sensor manufacturing, validation infrastructure, and R&D funding.
Between 2025 and 2030, the market is expected to grow from USD 0.5 billion to USD 767.4 million, accounting for 40.2% of total forecast growth. This phase will be defined by increased demand for battery monitoring systems, sensor miniaturization, and early deployment of wireless and multi-parameter sensing solutions. Manufacturers are actively investing in sensor fusion algorithms and digital integration with flight control and predictive maintenance platforms to establish competitive positioning.
From 2030 to 2035, market expansion accelerates further, adding USD 375.9 million and representing 59.8% of total growth. This period will be characterized by advanced health monitoring architectures, autonomous flight sensor networks, and deeper collaboration between sensor suppliers and airframe manufacturers.

Technology trends shaping the second half of the forecast period include:
- Integrated sensor-health monitoring platforms
- Weight-optimized, low-power sensor architectures
- AI-enabled data analytics for real-time fault detection
- Certification-ready sensor networks for autonomous operations
From a segmentation perspective, pressure sensors dominate the market, accounting for 36.7% share in 2025, due to their broad applicability across hydraulic systems, cabin pressurization, pneumatic diagnostics, and propulsion-related monitoring. Temperature sensors follow closely, driven by battery and power electronics thermal management needs. Electric aircraft applications represent 61.2% of total demand, reflecting the rapid adoption of fully electric propulsion platforms, while hybrid-electric aircraft account for the remaining share.
Regionally, Asia Pacific emerges as the fastest-growing market, supported by aggressive electric aviation programs in China and India. China leads with an 11.2% CAGR, driven by government-backed urban air mobility pilots and domestic aerospace manufacturing expansion. India follows at 10.4%, supported by aerospace modernization initiatives and indigenous electric aircraft development. Europe remains a stronghold of technological maturity, with Germany anchoring regional growth through advanced aerospace R&D and certification expertise. North America continues to benefit from NASA-led research programs and strong UAM investment activity.
Competition in the electric aircraft onboard sensors market remains moderately fragmented, with Honeywell, Safran, and Meggitt leading through established certification heritage and comprehensive sensor portfolios. Other key players such as TE Connectivity, AMETEK, Thales, RTX, and L3Harris Technologies compete through specialized sensing technologies, avionics integration capabilities, and system-level expertise. Market differentiation increasingly centers on reliability, certification readiness, weight reduction, and integration support rather than pricing alone.
As electric aviation moves from experimental programs toward commercial deployment, onboard sensors will remain foundational to safety, efficiency, and regulatory acceptance. The market’s steady growth trajectory reflects the indispensable role of sensing technologies in enabling the next generation of sustainable, electric-powered aircraft across global aviation ecosystems.
