A central air data computer avoided duplication of sensing equipment and could be more sophisticated and accurate. [8] The first air data computer was built by Kollsman Instruments for the B-52 bomber. [9] Bendix started producing a central air data computer in 1956 for use on US Air Force jet fighters. [10] Garrett AiResearch developed early ...
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.
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 attitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...
The air data module is a gas pressure sensor which converts mechanical forces created by gas pressure into digital signals that can be carried to the air data reference unit. ADMs generally have a maintenance bus and communication bus, and a connector on the housing for a pressurized gas line that is connected to the pitot tube or static ports.
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. Air data booms can be used as primary sensors or as a "measurement standard" of which primary sensors and instruments are ...

The F-14's Central Air Data Computer, also abbreviated as CADC, computes altitude, vertical speed, air speed, and mach number from sensor inputs such as pitot and static pressure and temperature. [1] From 1968 to 1970, the first CADC to use custom digital integrated circuits was developed for the F-14 .
All satellite communication whether audio or data is processed by the SDU. [1] The SDU communicates with an onboard MDDU (multi-purpose disk-drive unit) which maintains an updatable table of ground stations near the aircraft's position and the order of preference for selection of which ground station to use which thus guides the choice of ...
