Cessna Sky Courier UX: Autonomous Cargo Plane

What is the autonomous Cessna Sky Courier UX?

Cessna's Sky Courier UX is a conceptual cargo plane unlike any other. Unlike conventional cargo aircraft, it's designed without a cockpit, allowing it to fly without a crew. Textron Aviation and Merlin, a company specialized in autonomy, jointly unveiled this innovation during the Air, Space and Cyber Conference outside Washington in September 2023. The Sky Courier UX is engineered to carry nearly three thousand kilos of supplies (6,000 pounds) and can fly over 200 nautical miles per hour. It boasts an impressive 900 nautical-mile range, and its hold can accommodate three LD3 containers used for standard cargo. The absence of a traditional flight deck allows the UX version to optimize the space in the nose for cargo.

The Importance of Autonomy in Island Hopping Resupply

The Sky Courier UX targets a specific gap in the market – the resupply of remote areas in the Pacific for example. Small delivery drones can handle light loads, but they lack the capacity for significant resupply. A C-130, on the other hand, requires a crew and a suitable runway. The XU comes in between these two needs. However, due to the current absence of flight test dates and production timeline, its practical deployment remains uncertain. The UX model is intended for remote locations that cannot support human pilots safely.

Engineering Adaptations

The Kneeling Mechanism

The Sky Courier can also kneel, a manoeuvre that restricts the need for a proper runway. When loading or unloading, the plane drops its nose to the ground, transforming the empty cockpit into a loading ramp. Without any pilot seats to contend with, this space is maximized.

Boosting Range with Pratt and Whitney Engines

The Sky Courier UX will also include two Pratt & Whitney PT6 engines for optimal efficiency. These engines power the aircraft to a cruise speed exceeding 200 knots and ensure a range of 900 nautical miles.

The Merlin Pilot software

Without a crew, an aircraft cannot operate independently without a robust flight system. The flight deck is transformed into a loading opening and the new cockpit becomes a ground control room with Merlin's software.

Comparing the Sky Courier UX

The Cessna Sky Courier UX cannot be easily compared to existing aircraft as it targets a very specific niche market. It sits in the middle of small drones, intended for short-distance deliveries, and larger cargo planes which can carry tons of goods but need landing strip quality runways. This is the key value proposition of the Cessna Sky Courier UX.

From Concept to Reality

US Special Operations Command has shown interest in this technology. Having a $105 million contract with Textron Aviation and Merlin, puts the Sky Courier UX on a shortlist of technologies in which the US government is investing but it is still in early days and is still just a concept. The main drawback of the Sky Courier is its current status. No production timeline has been declared. Without a specific flight test date or production timeline, it presents a risk to those looking to invest or utilize the technology.

What's Next for Textron Aviation?

While the Sky Courier UX has its challenges, the concept itself receives a positive outlook on the future of unmanned cargo planes. FedEx has also shown interest - ordering 50 with options for 50 more. Following this purchase, FedEx will take delivery without a specific timeline yet. The Sky Courier UX offers a glimpse into what the next generation of autonomous cargo aircraft might look like.

The Promise of No Humans Onboard

To increase the reliability of the supply chain in remote areas, Textron Aviation and Merlin are attempting to remove the need for staff. This is a huge investment. Getting rid of humans presents a significant challenge, especially in specialized areas such as the Pacific. The US Special Operations Command is already investing in technologies that automate the C-130J through a 105 million dollar contract with Textron Aviation and Merlin. This demonstrates the growing demand for autonomous planes that can be loaded safely from a loading strip without the need of a human. The Sky Courier will likely continue to be discussed and built upon, by those who dream of a more efficient, safer supply chain in increasingly remote locations.
