All an Earth is, is a common reference point.
Ships are fairly easy, they are big bits of metal and so like cars you use the hull as ground. There is a small complication in that some ships/ocean structures deliberately generate a potential difference between the hull and the sea water to resist corrosion.

Aircraft are more complicated, they are subject to greater electrical fileds, flying through thunderstorms etc and have a lot more complicated electronics on them.
Fundementally though they just employ the same system as your house - all the ground lines are connected back to a common reference point ( a star earth) somewhere in the plane. Great care is taken that all parts of the plane are well earthed/well connected together because a lightning strike on one piece of metal will generate a lot of charge and if the next priece of metal isn't well connected to it there will a large potential difference which can cause sparks and fires.

The earthing system is an important safety measure that is used in aircraft and ships to protect against electric shock and to ensure proper functioning of electrical equipment. In aircraft, the earthing system is commonly known as the "grounding" system, while in ships it is referred to as the "bonding" system.

In aircraft, the earthing system is essential for the safe operation of electronic devices, such as navigation systems and communication equipment. This is achieved by connecting all metal parts of the aircraft, including the airframe, engine, and other components, to a common ground point. This ground point is usually located on the aircraft's structure and is connected to the earth through a grounding cable. This ensures that any electrical current is safely dissipated into the ground, preventing potential hazards for passengers and crew.

In ships, the earthing system is critical for the protection of the ship's hull and equipment from corrosion. It also helps to prevent electrical interference and ensures that all electrical equipment on board is functioning properly. The earthing system in ships is similar to that of aircraft, with all metal parts connected to a common ground point. However, due to the size and complexity of ships, the earthing system may also include additional measures such as bonding cables and anodes.

To properly implement the earthing system in aircraft and ships, it is important to follow specific guidelines and procedures. This includes regularly checking and maintaining all connections and ensuring that all components are securely grounded. It is also important to use high-quality materials and equipment to ensure the effectiveness of the earthing system.

In conclusion, the earthing system is a crucial safety measure in both aircraft and ships. By properly implementing and maintaining this system, we can ensure the safe and efficient operation of these vehicles.
