Correct option is B
The correct answer is (b) They can transfer the charge accumulated on their surfaces beingrubbed by air particles. Aircraft accumulate static charge while flying due to the friction between the aircraft's surface and the air particles. This process is called triboelectric charging, where the friction between air and the aircraft body creates an electrical charge. To safely dissipate this static charge and prevent the build-up of potentially dangerous electric potential, aircraft are equipped with conducting tyres. These tyres help to transfer and discharge the accumulated charge safely when the aircraft is on the ground, ensuring that no static electricity causes sparks or other safety issues during landing or while taxiing.
Information Booster: ● Static electricity builds up on an aircraft due to its interaction with air particles at high speeds during flight. ● Conducting tyres help in dissipating static charge once the aircraft is in contact with the ground, preventing the risk of sparks. ● Aircraft tyres contain conductive materials (like carbon compounds) that help in grounding the charge accumulated during the flight. ● This feature is crucial for ensuring safety during landing, as static discharge without control can pose a fire hazard. ● Other measures, such as bonding straps and static dischargers on the wings, are also used to manage static electricity on aircraft. ● Conducting tyres are a vital component in the electrical grounding system of an aircraft.
