The EDSU-200 fly-by-wire control system is a digital-analog remote control system for the BE-200 amphibian airplane. 2 operational modes are available: basic digital & standby analogue (at a failure of the basic digital part). In the standby mode the EDSU-200 provides acceptable level of controllability and stability characteristics at a manual control & manual trimming
in the longitudinal channel. Power to the EDSU-200 is supplied by two independent 27V DC power units which work in buffer with electrical
storage batteries, and two independent 3-phase 115/200V 400Hz supply units. The hydraulic system is fed by three independent
hydraulics. The system meets the requirements of ENLGC-3 and AP-25.
