ASPD-4525 Digital Airspeed Sensor for Fixed-Wing Flight Controllers

GPS ground speed and true airspeed are not the same thing - a headwind or tailwind throws ground-speed-only navigation off in exactly the way a fixed-wing autopilot needs to compensate for during cruise and landing approach. This sensor feeds genuine airspeed data from its ASPD-4525 pressure chip directly to the flight controller, giving a fixed-wing autopilot the real airflow reference it needs for accurate stall-speed margins and wind-compensated navigation that GPS ground speed alone can't provide.
