Aircraft Electrical System

Modern day aircraft very much rely on electrical and electronic systems. Aircraft electrical system powers the lights, flight instruments, navigation aids, radios and engine starting. In early days aircraft had no electrical component or system. As the distance and altitude of flying increased more and more complex systems were incorporated. Today electrical and electronic systems became essential in aircraft design.

Aircraft electrical system mainly composed of

  • Power sources
  • Control devices
  • Conversion devices
  • Protection devices
  • Power distribution system
  • and electrical loads

However advanced electrical systems may incorporate additional components such as transformer rectifier units, hydraulic motors and ram air turbines
