Aircraft build up a considerable amount of static electric charge during flight due to friction with air, dust, and precipitation. This charge needs to be safely dissipated upon landing. Conducting tyres provide a low-resistance path for this accumulated static charge to flow from the aircraft's structure to the ground, thus neutralizing the charge gradually and preventing a sudden electrostatic discharge or spark that could ignite flammable fuel vapours near the ground.
Which one of the following is the most appropriate reason for aircraft being equipped with conducting tyres ?
