AIRCRAFT BATTERY Meaning and
Definition
-
An aircraft battery is an essential power source specifically designed to supply electrical energy to an aircraft's electrical system. It is a rechargeable and portable device that provides the necessary electrical power for various functions and systems within an aircraft.
Equipped with multiple cells connected in series, an aircraft battery primarily consists of lead-acid or nickel-cadmium (Ni-Cd) chemistry. The lead-acid type typically offers a high capacity and is commonly used in general aviation aircraft, while the Ni-Cd type typically provides a lower capacity but possesses a longer lifespan and is often used in commercial or military aircraft.
The aircraft battery serves several critical functions. Firstly, it powers the aircraft's starting system, providing the necessary electrical energy to initiate the engine's ignition process. Additionally, it supplies power to essential systems such as communication, navigation, emergency lighting, avionics, and auxiliary functions when the main engines are not running or in the event of an electrical failure. In some cases, it may also act as a backup power source for the aircraft's emergency systems.
To ensure reliable performance, aircraft batteries undergo rigorous testing and adhere to specific aviation standards and regulations. They must comply with stringent safety requirements to minimize the risk of fire or explosion, as well as exhibit durability to withstand the environmental conditions encountered during flight.
Aircraft batteries are vital for the safe operation of an aircraft, providing crucial electrical power in various scenarios to enable essential functions and ensure the safety and dependability of the aircraft's electrical system.
Etymology of AIRCRAFT BATTERY
The word "aircraft battery" does not have a specific etymology, as it is a combination of two common English terms: "aircraft" and "battery".
The term "aircraft" originated from the combination of the words "air" and "craft". "Air" comes from the Middle English word "air" or "ayr", which ultimately derives from the Latin word "aēr" meaning "air" or "atmosphere". "Craft" comes from the Old English word "cræft", meaning "power" or "ability". In the context of "aircraft", "craft" refers to a vehicle designed for travel or transport in the air.
The term "battery" has a different origin but has historically been used to refer to a device that produces electrical energy. The term comes from the French word "batterie", which originally referred to a group of cannons or artillery pieces.
