Question

You have a composite aircraft with electrically resistive fibre-glass wings. Howcould you discharge this to avoid having sparks ignite during refueling? [Short answerplease]

Answer 1

when the aircraft is in air the winds is constantly stricking or rubbing the aircraft frame ,and we know that when two suitable material is rubbed the electrons jump from one material to another and objects get charged . Same happens with aircraft as well ,it get charged . So to avoid an accident like fire due to spark while refueling the aircraft, we have a certain areas which is especially designed for static discharged ,so that the excess charge can go back to the atmosphere where they came from . The end of the wicks is the place where is happens , its made like pointy brush like structure so the discharge can happen with ease (becaure the charge density is high near pointy parts of the object and were the chage density is high there sparks generate ).
