Postage-Stamp-Sized Ice Sensors Could Improve Aircraft Safety

New aircraft sensors roughly the size of a postage stamp could help pilots make safer decisions in real time, their creators say.

The sensors, developed by a University of Surrey startup, measure approximately 3 centimeters (1.2 inches) in length and are designed to detect ice accumulation and assess its impact on aircraft performance.

Scientists involved in the project say the system will enable pilots to monitor wing conditions during flight, and the small size of the sensors allows installation on smaller surfaces such as helicopter blades.

Dr. David Birch of Surrey Sensors said: “What’s important is not just detecting ice, but understanding how it is affecting the aircraft’s performance.”

He added: “Combining different sensing approaches will help to make these measurements far more robust – particularly in the harsh conditions where current systems are most vulnerable.”

“This technology is about giving aircraft a much clearer picture of what’s happening to their wings in real time,” Birch said.

A university spokesperson said the sensors, created in collaboration with the Canadian Flight Test Centre of Excellence, integrate two different technologies to alert pilots.

The university stated that the sensors can operate in extreme conditions and may improve fuel efficiency by reducing reliance on anti-icing systems.
