This is a significant source of charge buildup, especially in dry air.<br \/>\nStatement 2 is correct: The operation of various electronic systems within the aircraft can also contribute to the accumulation of static charge on the aircraft&#8217;s structure.<br \/>\nConducting rubber tyres provide a path for this accumulated static charge to safely discharge to the ground upon landing, preventing the build-up of a large potential difference between the aircraft and the ground, which could otherwise lead to a spark. Such a spark could pose a fire hazard, especially during refueling, or cause damage to sensitive electronic components. Therefore, both reasons contribute to the necessity of conducting tyres.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Why are the tyres of aircrafts made of conducting rubber? 1.
