Smart Display Unit-I

Smart Display Unit-I

Smart Display Unit-I works as a centralized monitoring and control unit of the navigation and mission avionics of the fighter aircraft. SDU-I performs the functions of a display computer and performs these tasks through the use of 1553B bus and discrete I/Os. SDU-I receives data from the Line Replaceable Units (LRUs) of the avionics system via the 1553B bus and discrete signal interfaces.
