An air data module is a component of the navigation system. 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. This pressure information is received and processed by the Air Data Reference (ADR) component of the Air Data Inertial Reference Unit (ADIRU).This processed information is then sent to one or more display management computers that present information on the cockpit's primary flight display. Airspeed information is also sent to the flight computers and other electronics,including the autoflight subsystem

Selection of the correct takeoff runway on the FMGC prior to each flight is necessary because:
