How Airspeed Sensors Work

According to Hackaday contributor Zoe Skyforest, airspeed sensors are essential aircraft instruments that measure how fast a plane is moving through the air—not relative to the ground, but relative to the surrounding air mass.

This pressure data gets processed and displayed to the pilot, helping ensure the aircraft stays within safe operating speeds.
