</style><div role="note" class="hatnote navigation-not-searchable">This article is about air data computers in general. For the specific CADC used in the F-14, see <a href="F-14_CADC" title="F-14 CADC">F-14 CADC</a>.</div>

<p>An <b>air data computer</b> (<b>ADC</b>) or <b>central air data computer</b> (<b>CADC</b>) computes <a href="Altitude" title="Altitude">altitude</a>, vertical speed, air speed, and <a href="Mach_number" title="Mach number">Mach number</a> from pressure and temperature inputs.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> It is an essential <a href="Avionics" title="Avionics">avionics</a> component found in modern aircraft. This computer, rather than individual <a href="Flight_instruments" title="Flight instruments">instruments</a>, can determine the <a href="Calibrated_airspeed" title="Calibrated airspeed">calibrated airspeed</a>, Mach number, altitude, and <a href="Vertical_speed_indicator" class="mw-redirect" title="Vertical speed indicator">altitude trend</a> data from an aircraft's <a href="Pitot-static_system" class="mw-redirect" title="Pitot-static system">pitot-static system</a>.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> In some very high-speed aircraft such as the <a href="Space_Shuttle" title="Space Shuttle">Space Shuttle</a>, <a href="Equivalent_airspeed" title="Equivalent airspeed">equivalent airspeed</a> is calculated instead of calibrated airspeed. Air data computers usually also have an input of <a href="Total_air_temperature" title="Total air temperature">total air temperature</a>. This enables the computation of static air temperature and <a href="True_airspeed" title="True airspeed">true airspeed</a>.

</p>

<div class="mw-heading mw-heading2"><h2 id="Models">Models</h2></div>

<p>In <a href="Airbus" title="Airbus">Airbus</a> aircraft the air data computer is combined with attitude, heading and navigation sources in a single unit known as the <a href="Air_Data_Inertial_Reference_Unit" class="mw-redirect" title="Air Data Inertial Reference Unit">Air Data Inertial Reference Unit</a> (ADIRU) which has now been replaced by the Global Navigation Air Data Inertial Reference System (GNADIRS).<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>

</p><p>On the Embraer <a href="Embraer_E-Jet_family" title="Embraer E-Jet family">Embraer E-Jet family</a> the concept has been refined further by splitting air data acquisition and measuring – performed by combined pitot/static "air data smart probes" with integrated sensors – and computation of parameters performed by "air data applications" (ADA) executed on non-dedicated processing units. As all information from the sensors is transmitted electrically, routing of pitot and static pressure lines through the aircraft and associated maintenance tasks is avoided.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup>

</p><p>In simpler aircraft and helicopters, the air data computers, generally two in number, and smaller, lighter and simpler than an ADIRU, may be called air data units, although their internal computational power is still significant. They commonly have the pitot and static pressure inputs, as well as <a href="Outside_air_temperature" title="Outside air temperature">outside air temperature</a> from a <a href="Platinum_resistance_thermometer" class="mw-redirect" title="Platinum resistance thermometer">platinum resistance thermometer</a> and may control heating of the pitot tube and static vent to prevent blockage due to ice. On simpler aircraft, there is usually not a fly-by-wire system so the outputs are typically to the cockpit altimeters or display system, flight data recorder and autopilot system. Output interfaces typically are <a href="ARINC_429" title="ARINC 429">ARINC 429</a>, <a href="Gillham_code" title="Gillham code">Gillham</a> or even <a href="IEEE_1394" title="IEEE 1394">IEEE 1394</a> (Firewire). The data provided may be true airspeed, pressure altitude, <a href="Density_altitude" title="Density altitude">density altitude</a> and <a href="Outside_Air_Temperature" class="mw-redirect" title="Outside Air Temperature">Outside Air Temperature</a> (OAT), but with no involvement in aircraft attitude or heading, as there are no <a href="Gyroscope" title="Gyroscope">gyroscopes</a> or <a href="Accelerometer" title="Accelerometer">accelerometers</a> fitted internally. These devices are usually autonomous and do not require pilot input, merely sending continuously updated data to the recipient systems while the aircraft is powered up. Some, like the Enhanced Software Configurable Air Data Unit (ESCADU)<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> are software configurable to suit many different aircraft applications.

</p><p>Apart from commercial ADCs, there are available do-it-yourself, and open-source implementations.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<p>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. A central air data computer avoided duplication of sensing equipment and could be more sophisticated and accurate.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> The first air data computer was built by Kollsman Instruments for the <a href="B-52_bomber" class="mw-redirect" title="B-52 bomber">B-52 bomber</a>.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> <a href="Bendix_Corporation" title="Bendix Corporation">Bendix</a> started producing a central air data computer in 1956 for use on US Air Force jet fighters.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> <a href="Garrett_AiResearch" title="Garrett AiResearch">Garrett AiResearch</a> developed early central air data computer systems that integrated pneumatic, electrical, and electronic components.<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup>
