A Single-Engine Rating is a certification that allows a pilot to operate aircraft with only one engine. This rating is essential for pilots who wish to fly smaller planes, as it demonstrates their ability to handle the specific challenges associated with single-engine flight. To obtain a Single-Engine Rating, pilots must complete training that includes both ground school and flight instruction. They must also pass a written exam and a practical flight test, ensuring they have the necessary skills and knowledge to safely operate single-engine aircraft.
