Modern aircraft relies on the brake system to slow down the aircraft. The main components of the brakes are automatic brake selector switches, brake pedals, and emergency brake handles. In the process of using the brakes, the pilots are concerned with the status of the braking system, especially when the normal function fails. If there is no antiskid function during the emergency brake, any pilot’s wrong operation will result in the blasted tire, and possibly runway overrun. A design analysis of the typical civil brake pressure display can provide reference for the civil aircraft brake system design.
