In conclusion, after completing the assignment on … for this assignment. I know more about electronic devices and their functions, the coordinator and also the insulation on the board and how the components flow flows and for what it is used. I also need to know more about all the components used in the circuit board. In fact, we have to learn about this because if the aircraft is in operation there is damage in the cockpit section we can repair the part. Maybe it’s because of the electric current in the irregular circuit board. So we have to be careful in installing the components in the circuit so that the managed aircraft does not experience any problems.
