Multiengine aircraft are airplanes equipped with two or more engines. These engines can provide increased power, allowing for better performance, especially during takeoff and climb. They are commonly used for commercial flights, cargo transport, and military operations due to their reliability and ability to continue flying even if one engine fails. The design of multiengine aircraft enhances safety and efficiency. Pilots often require additional training and certification to operate these planes, as managing multiple engines involves more complex procedures. Examples of multiengine aircraft include the Piper Seneca and the Beechcraft Baron.
