A successful example of the development of digital control by making maximum use of program control, a feature of digital control, is the brake-by-wire system developed for small domestic aircraft. This system has a dual redundant system, but by program-correcting the highly nonlinear carbon brake characteristics and the characteristics of the brake control hydraulic valve, it has succeeded in maintaining the same brake control characteristics as before. We believe that our advanced electronic control technology will be the greatest product that provides safety and peace of mind to aircraft operators.
