  2. Air quality index - Wikipedia

    en.wikipedia.org/wiki/Air_quality_index

    Historical air monitoring data including AQI charts and maps are available at EPA's AirData website. [53] There is a free email subscription service for New York inhabitants – AirNYC. [54] Subscribers get notifications about the changes in the AQI values for the selected location (e.g. home address), based on air quality conditions.

  3. Air data boom - Wikipedia

    en.wikipedia.org/wiki/Air_data_boom

    X-15 rocket-powered research aircraft, with nose air data boom. An air data boom provides air pressure, temperature, and airflow direction data to data acquisition systems for the computation of air, ground, and water vehicle orientation, speed, altitude/depth, and related information.

  4. Air data computer - Wikipedia

    en.wikipedia.org/wiki/Air_data_computer

    The Bendix Central Air Data Computer contains complex electromechanical mechanisms. Electrical-mechanical air data computers were developed in the early 1950s to provide a central source of airspeed, altitude, and other signals to avionic systems that needed this data.

  6. Synthetic air data system - Wikipedia

    en.wikipedia.org/wiki/Synthetic_air_data_system

    A synthetic air data system (SADS) is an alternative air data system that can produce synthetic air data quantities without directly measuring the air data. It uses other information such as GPS, wind information, the aircraft's attitude, and aerodynamic properties to estimate or infer the air data quantities.

  7. Air data inertial reference unit - Wikipedia

    en.wikipedia.org/wiki/Air_data_inertial...

    An Air Data Inertial Reference Unit (ADIRU) is a key component of the integrated Air Data Inertial Reference System (ADIRS), which supplies air data (airspeed, angle of attack and altitude) and inertial reference (position and altitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...

  8. Air data module - Wikipedia

    en.wikipedia.org/wiki/Air_data_module

    Illustration of the airspeed indication and detection system on fly-by-wire aircraft. An air data module is a component of the navigation system. [1] Each unit converts pneumatic (air pressure) information from a pitot tube or a static port into numerical information which is sent on a data bus. [2]

  9. True airspeed - Wikipedia

    en.wikipedia.org/wiki/True_airspeed

    A free windows calculator which converts between various airspeeds (true / equivalent / calibrated) according to the appropriate atmospheric (standard and not standard!) conditions; Android application for airspeed conversion in different atmospheric conditions; True, Equivalent, and Calibrated Airspeed at MathPages; Newbyte airspeed converter
