38-Which of the following statements regarding an aircraft being struck by lightning is true?

050 16788 Flight Hazards

The crew of an aircraft made of conductive material (e.g. metal) will generally suffer greater adverse effects due to lightning discharge than the crew of an aircraft made of non-conductive composite material. The dimension of the damage caused by the lightning stroke is reciprocally proportional to the strength of the electric field the aircraft intruded. The flight crew might have temporary difficulties in determining the current attitude of flight. Though flying through an electric field, the aircraft itself is not a charge carrier and therefore it cannot initiate a lightning discharge.
