Can You Pass This Aircraft Electrical System Test?
Air transport is the fastest means of transportation, and it does not come with some dangers too. Being an electrical engineer is one thing, but being an aircraft electrical system engineer is another. This job requires more knowledge but picks some from the basics. These are the same questions you will see in the CBT, so try to know the answers as well. For the Multiple Choice, try to understand the answer rather than memorize it.
