Special Features:

Provides the aircraft with altitude and airspeed data for the electronic flight instrument syste (efis) auto pilot, flight recorder; transponder radar, and traffic alert and collision avoidance system(tcas)

Properties:

A computer specifically designed to convert basic air data input signals into electrical output signals representing the necessary flight parameters such as pressure altitude, mach number, airspeed, and impact pressure.
