What is the potential risk of using a GPU with an unstable voltage output?

The potential risk of using a GPU with an unstable voltage output is damage to the aircraft's electrical systems and avionics. Aircraft electrical systems are designed to operate within a specific voltage range. A GPU with an unstable voltage output, characterized by voltage fluctuations or surges, can deliver power outside of this acceptable range. Overvoltage can cause overheating, component failure, and even permanent damage to sensitive electronic equipment. Undervoltage can result in malfunctions and unreliable operation of aircraft systems. The avionics, which control navigation, communication, and other critical functions, are particularly susceptible to damage from voltage irregularities. Therefore, it is imperative to ensure that the GPU provides a stable and regulated voltage output that matches the aircraft's requirements to prevent costly repairs and potential safety hazards.
