What Does PFBIT Stand For?

PFBIT stands for Pre Flight Built In Test

PFBIT, or Pre Flight Built In Test, refers to a diagnostic procedure conducted prior to the launch of an aircraft or spacecraft. This automated test system verifies the operational status and functionality of critical systems and components, ensuring they meet safety and performance standards. PFBIT enhances reliability by identifying and addressing potential issues before flight, thereby reducing the risk of system failures and improving overall mission success.
