A "Multi-Engine" refers to an aircraft that is powered by more than one engine. This design enhances performance, allowing for greater speed, increased payload capacity, and improved safety. If one engine fails, the aircraft can still operate using the remaining engines, making it a popular choice for commercial and cargo flights. Multi-engine aircraft are commonly used in various aviation sectors, including commercial aviation, cargo transport, and military operations. Pilots flying these aircraft must obtain a specific multi-engine rating to ensure they are trained to handle the complexities of operating multiple engines effectively.
