What Are Air Data Systems?
Air Data Systems (ADS) are integrated avionics solutions that measure and process atmospheric data, ensuring the safe and efficient operation of aerial platforms. In autonomous unmanned aerial vehicles (UAVs), ADS provides data that informs onboard decision-making, enabling self-directed navigation and environmental adaptation. For remote-controlled aircraft, ADS relays vital flight information to operators, aiding in manual control and situational awareness.
ADS is indispensable for maintaining flight stability, optimizing aerodynamic performance, and ensuring mission success in both autonomous and remote-controlled scenarios.
Key Components of an Air Data System
Air Data Computer (ADC)

Air Data Computer ADC by Inertial Labs
The air data computer is the processing core of ADS, translating inputs from various sensors into actionable metrics such as altitude, Mach number, indicated airspeed, and true airspeed. For autonomous UAVs, ADCs feed data to flight control algorithms. For remote-controlled platforms, they provide operators with precise real-time information to guide decision-making.
Pitot Tubes
Pitot tubes measure dynamic pressure, enabling accurate airspeed calculations. These devices are critical for ensuring the stable operation of aircraft, whether the control is automated or manual. For remote-controlled systems, pitot tube data provides operators with direct feedback on flight conditions.
Static Ports
Static ports measure ambient atmospheric pressure, which, when combined with pitot tube data, allows for the determination of altitude and airspeed. This data ensures that autonomous UAVs and remote-controlled aircraft maintain their intended flight profiles.
Temperature Sensors
Temperature sensors, including Total Air Temperature (TAT) probes, measure external air temperature. This data influences true airspeed calculations and enables optimal aerodynamic performance, critical for unmanned and remote-controlled operations alike.
Supplementary Sensors
Additional components, such as barometers, magnetometers, and angle-of-attack sensors, enhance ADS functionality by enhancing aerodynamic stability, altitude accuracy, and navigation precision.
The Role of AHRS in Air Data Systems
An Attitude and Heading Reference System (AHRS) often complements Air Data Systems, particularly in advanced UAVs and remote-controlled aircraft. While the ADS focuses on measuring atmospheric parameters such as airspeed, altitude, and pressure, AHRS provides critical orientation data, including pitch, roll, and yaw. This combination enhances situational awareness and flight stability, ensuring precise maneuvering and reliable navigation. By integrating data from inertial sensors, magnetometers, and GNSS/GPS, AHRS enables smoother flight control, particularly in autonomous systems, where maintaining orientation is crucial for mission success. When paired with ADS, AHRS significantly improves the accuracy and responsiveness of onboard flight control and navigation systems.
How Air Data Systems Enhance Operations
Autonomous UAVs
ADS is a cornerstone of flight control and navigation for autonomous UAVs. By providing inputs on airspeed, altitude, and atmospheric conditions, ADS allows UAVs to adapt to changing environments, maintain optimal flight paths, and execute missions without human intervention.
