Electrical bus
In aviation, an electrical bus is a common point in an aircraft's electrical system that distributes power to various components. It's like a circuit that delivers electrical energy from a source, such as a battery or generator, to different systems like avionics, lighting, and instruments.
Elaboration
Distribution Point
Electrical buses act as central hubs where multiple electrical circuits are connected to receive power.
Voltage and Power
Buses can be designed for different voltage levels (DC or AC) and power requirements, and some even have shed buses that are de-energized first in case of a power shortage.
Importance
Buses are crucial for reliable and safe operation of aircraft electrical systems.
Essential Buses
Some buses, like essential buses, are designed to remain powered even in emergency situations, ensuring critical systems like navigation and flight controls stay operational.
Shed Buses
These buses power non-essential systems that can be de-energized during emergencies to conserve power.
Bus Naming Conventions
Buses are typically named based on their power source (e.g., DC bus, AC bus) or the type of components they serve (e.g., essential bus, avionics bus).
