How many grounding points are present in the MLG?

The correct choice, which indicates that there are two grounding points present in the Main Landing Gear (MLG) of the F/A-18 E/F, is based on the aircraft's design and grounding requirements for safety and electrical maintenance.

Grounding points are critical for ensuring that any static electricity or transient electric charges are safely discharged to the ground, thereby preventing electrical shock hazards and ensuring the safety of personnel working on or near the aircraft. In the F/A-18, these grounding points are strategically located to maintain grounding integrity and efficiency.

In practice, while the MLG itself may feature various structural components and systems, the established protocol specifies two designated grounding points that are used by flight line personnel when performing maintenance operations or preparing the aircraft for flight. This knowledge is crucial for plane captains and maintenance crews to ensure they adhere to safety protocols during ground operations.

This understanding not only reinforces the importance of grounding points but also highlights their specific role in effective aircraft maintenance and personnel safety.
