The SDU-10MK remote control system is a digital-
analogue system and is an exchange
for the mechanical control circuit.
The system ensures a high efficiency level
of an airplane (at the expense of automatic limiting
of marginal flight modes, control of an airplane both
through basic, and auxiliary control surfaces, stabili-
ty and controllability with the help of SDU contours.
The SDU-10MK remote control system
is used on the Su-30MKI aircraft.
