Freight aircraft are specialized airplanes designed primarily for transporting cargo rather than passengers. They come in various sizes and configurations, including dedicated freighters and converted passenger planes. These aircraft can carry large volumes of goods, ranging from small packages to heavy machinery, and are essential for global trade and logistics. Typically, freight aircraft feature wide cargo doors and a flat floor to facilitate easy loading and unloading. They are equipped with advanced navigation and safety systems to operate efficiently in various weather conditions. Major operators of freight aircraft include companies like FedEx and UPS, which rely on them for timely deliveries.
