Merlin, an American start-up company, recently released the "Merlin Pilot for Commercial Cargo" artificial intelligence flight system for the commercial cargo market. It attempts to bring fully unmanned capabilities to large cargo aircraft. It is regarded as an important signal that autonomous flight technology has entered a new stage.
In recent years, autonomous flight technology has advanced by leaps and bounds, and the industry's focus is shifting from "whether aircraft can take off and land without control" to "how to operate safely in a real airspace environment", including collaboration with various types of manned aircraft and air traffic control systems, as well as safe handling in complex weather and emergency situations. At present, most of the autonomous flight systems that have been put into trials or preliminary applications are still concentrated on small or medium-sized fixed-wing aircraft, such as modified models such as Cessna 150 and Cessna 208B "Caravan". However, those that really have broad commercial prospects are the heavy-duty cargo fleet represented by large cargo aircraft such as Lockheed Martin "Hercules".
Boeing's market forecast shows that in the next 20 years, the global demand for new and modified large cargo aircraft will total approximately 2,800, which will significantly increase the size of the cargo fleet. At the same time, the global civil aviation industry is facing a structural pilot shortage, which poses serious challenges to both cargo and passenger aviation. Compared with the public's still huge psychological threshold for "cockpit-less passenger aircraft", the introduction of highly autonomous or even completely unmanned systems in the field of cargo aircraft without passengers is regarded as a more realistic and easier to be accepted by the market.
Merlin was founded in 2018 and is headquartered in Boston. Over the past few years, it has conducted flight tests on five different aircraft models and conducted actual operational tests on commercial routes in Alaska and New Zealand to verify the reliability and adaptability of the system in complex environments. The Merlin Pilot launched this time belongs to the company's "Condor" product family for large multi-crew aircraft. The design concept emphasizes "aircraft-independent" and can be integrated into the existing airframe through modification, rather than serving only a single new aircraft model.
In terms of technical architecture, Merlin Pilot adopts a multi-sensor fusion solution, comprehensively using global satellite positioning systems, inertial navigation systems, radar altimeters, radio altimeters and multiple types of environmental sensors to build real-time perception of the aircraft's attitude, position and surrounding airspace. Paired with dedicated flight control software, the system can perform flight path planning, attitude control and obstacle avoidance decisions without direct human control, enabling active avoidance of other aircraft and airborne obstacles. It is worth noting that Merlin has also integrated a natural language processing model into the system to understand air traffic control instructions and inquiries, and make voice responses in a manner similar to human pilots, aiming to smoothly connect with the existing air traffic control operation process.
In terms of supervision and airworthiness, Merlin chose a "step-by-step" introduction strategy to lower the certification threshold and accumulate operational data. According to the company's plan, the system will first fly with a human safety driver in the role of "intelligent co-pilot" and participate in decision-making and operations through human-machine collaboration. This model is not only more in line with the risk control requirements of regulatory agencies such as the U.S. Federal Aviation Administration (FAA), but also helps the system continue to collect data during long-term operation, providing a basis for future applications for fully autonomous flight certification.
Matt George, founder and CEO of Merlin, said that the shortage of pilots has had a structural impact on operators, and the cargo aircraft conversion market is in a high boom cycle. The simultaneous embedding of autonomous flight capabilities in projects such as passenger conversion to cargo provides a "time window" for industry upgrades. He emphasized that the goal of the "Condor" program is to achieve large-scale deployment of autonomous capabilities on large, multi-crew aircraft, and Merlin Pilot is the core component of it. It is working with regulatory authorities to promote airworthiness certification through real military aircraft platforms, while taking into account the integration of existing fleets in order to quickly implement it in the commercial cargo field.
From an industry perspective, as autonomous flight systems continue to advance on both the technical and regulatory fronts, the prospect of large cargo aircraft achieving high-level automation or even completely unmanned operations is gradually moving from concept exploration to project implementation. It is generally expected in the industry that due to the superposition of multiple factors such as pilot resource constraints, expanding cargo demand, and continued advances in computing power and sensing technology, solutions represented by Merlin may reshape the future operating model of cargo aviation.
