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.
A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal . [ 1 ] It is commonly applied to sonar , radar , and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum ).
The chirp pulse compression process transforms a long duration frequency-coded pulse into a narrow pulse of greatly increased amplitude. It is a technique used in radar and sonar systems because it is a method whereby a narrow pulse with high peak power can be derived from a long duration pulse with low peak power.
In Airbus aircraft the air data computer is combined with attitude, heading and navigation sources in a single unit known as the Air Data Inertial Reference Unit (ADIRU) which has now been replaced by the Global Navigation Air Data Inertial Reference System (GNADIRS).
The datalink control and display unit (DCDU) on an Airbus A330, the pilot interface for sending and receiving CPDLC messages. A similar product (FANS-A) was later developed by Airbus for the A340 and A330. Boeing also extended the range of aircraft supported to include the Boeing 777 and 767.
An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information for aircraft, including roll, pitch, and yaw. These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) [ 1 ] sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes ...
The system can be transported by truck, ship, or any suitable transport aircraft such as a C-130 or C-17, and can also be airlifted by helicopter. The transportable systems can be unpacked and installed to full operational capacity in several hours by 2 trained technicians.
The Airbus A320 family was the first airliner to feature a full glass cockpit and digital fly-by-wire flight control system. The only analogue instruments were the radio magnetic indicator, brake pressure indicator, standby altimeter and artificial horizon, the latter two being replaced by a digital integrated standby instrument system in later production models.
