Motor controllers and drives are electrical devices used to regulate motor speed, torque, and position outputs. The drive alters the power input to the motor to realize a desired output. Controller circuits are frequently consolidated with the drive circuits to form a single stand-alone unit, and as such, the terms motor drive and motor controller are frequently used interchangeably. The four basic motor controller and drive types are AC, DC, servo, and stepper. Each type has its own input power type adjusted to the desired output function to match with its intended application.

The aircraft fuel system is crucial to flight operations, providing the engines with a stable flow of fuel from the fuel tanks. As aircraft are constantly in changing environments with extreme conditions, the fuel system must ensure that there is always enough fuel to accommodate for any altitude, attitude, and more. For smaller aircraft, fuel systems often come in one of two types, those being the gravity-feed and fuel-pump system.
