What is the proper procedure for grounding an aircraft?

• A. Ground to aircraft first, then to the ground
• B. Ground to the ground first, then to aircraft
• C. Ground to maintenance equipment first
• D. Do not ground aircraft at all

Answer: (A)

Grounding an aircraft is an essential safety procedure designed to prevent the buildup of static electricity, which can create sparks and pose a risk of fire or explosion, particularly when refueling or conducting maintenance. The proper procedure is to connect the grounding equipment to the aircraft first and then to a grounding point, such as a grounding rod or plate. This method ensures that the aircraft is electrically bonded to the ground before other components are connected, minimizing the risk of static discharge during operations. By establishing a ground connection to the aircraft first, any static charges that may be present on the aircraft are safely dissipated to the ground, which protects personnel and equipment during refueling or maintenance activities. In contrast, connecting the grounding equipment to the ground first could potentially allow for static charges to remain on the aircraft until the connection is made, increasing the risk of discharge when personnel or other equipment come into contact with the aircraft. Therefore, starting with the aircraft ensures a safer and more reliable ground procedure.
