What is the voltage that can be present in a windshield during flight?

The voltage that can be present in a windshield during flight can indeed reach up to 100,000 volts. This high voltage is primarily a result of the electrostatic charges that can accumulate on the surface of the aircraft due to flight through the atmosphere. Factors such as the aircraft's speed, atmospheric conditions, and humidity can all influence the buildup of these charges.

Windshields are designed to withstand these high voltage levels to ensure the safety and integrity of the cockpit. Engineers take these electrical considerations into account during the design process to safeguard against electrical interference and damage. Therefore, understanding that the potential for high voltage is significant, especially in the context of aviation environments, is essential for ensuring both operational safety and proper maintenance practices.
