How is a medium aircraft defined based on its take-off weight?

A medium aircraft is defined as one that has a take-off weight greater than 7,000 kg but less than 136,000 kg. This classification is important in aviation as it helps to categorize aircraft for various regulatory, operational, and safety considerations.

The range of take-off weight specified serves to differentiate medium aircraft from small and large aircraft. Aircraft with a maximum take-off weight under 7,000 kg typically fall into the small aircraft category, while those with a maximum take-off weight exceeding 136,000 kg are classified as large aircraft. By establishing these weight categories, authorities like the FAA and ICAO can apply different safety regulations, certification processes, and operational requirements tailored to the performance and complexity of the aircraft in each category.

This delineation allows for efficient air traffic management, safety protocols, and maintenance policies tailored to the characteristics of the aircraft being operated. Understanding these classifications is critical for pilots, operators, and aviation personnel when discussing capabilities, regulations, and safety measures associated with different types of aircraft.
