A multi-engine pilot is a pilot with credentials that allow them to operate an aircraft with more than one engine. The Federal Aviation Administration (FAA) has a recommended syllabus for institutions offering this training. As a pilot with the multi-engine land (MEL) rating, you can fly larger planes, whether as a private or commercial operator. You must perform several duties before and after flights, including inspection of the airplane, flight plan submission, and maintenance of safe operation during flight. Federal regulations dictate the maximum amount of hours you can fly, but you typically work outside of the standard 9-to-5 weekday schedule.
