Certification Center Canada (CCC) and UK-based Surrey Sensors are jointly developing a new generation of micro air data sensors intended to improve the reliability of airspeed and altitude measurements compared with conventional pitot-static systems.
The project focuses on miniature MEMS-type pressure sensors integrated into a redundant architecture designed to deliver more consistent air data and to reduce sensitivity to vibration and pitot probe blockage. These micro-sensors can be deployed in higher numbers within a compact volume, enabling multiple measurement points instead of relying on a small number of exposed probes.
The system aims to address known limitations of current air data installations, including obstruction from ice, insects or debris, as well as errors induced by vibration or unfavorable aerodynamic configurations. By combining inputs from many sensors through advanced signal processing, the architecture is intended to filter out local anomalies and maintain coherent air data across all phases of flight.
Target applications include business aviation and general aviation aircraft, with potential for use on new aircraft types or in retrofit programs, subject to regulatory approval. The technology remains in development and validation, with no published timeline for large-scale flight testing, certification or entry into service, and no disclosed commercial figures or specific aircraft program commitments.
