Imagine a world where aircraft soar high in the skies, accomplishing complex missions without a pilot on board. This is not a scenario from a futuristic sci-fi movie but rather a reality in today’s aviation industry. The protagonists in this case are known as Remotely Piloted Aircraft (RPA), forming a part of what is globally recognized as Remotely Piloted Aircraft Systems (RPAS). These remarkable systems are transforming the way we approach air travel, surveillance, reconnaissance, and a plethora of other applications.

Introduction To Remotely Piloted Aircraft Systems (RPAS)

The International Civil Aviation Organisation (ICAO) defines an RPA as “An aircraft where the flying pilot is not on board the aircraft.” This definition places RPAs as a subcategory of unmanned aircraft. A remotely piloted aircraft system (RPAS) thus consists of a remotely piloted aircraft, remote pilot stations, command and control links, and other system elements as required.

Remarkably, the RPAS has emerged as a significant element within the broader term Unmanned Aircraft System (UAS), with the term ‘drone’ often used as an informal substitute. The focus of most information available today, including resources such as SKYbrary, pertains to small RPAS, largely due to their integration into national airspace systems and the corresponding safety issues that arise.

What Is A Remotely Piloted Aircraft

A remotely piloted aircraft, as the name suggests, is an aircraft that does not require a pilot to be physically present inside to fly it. It is controlled from a remote pilot station, integrating seamlessly into the air traffic management system just like any manned aircraft.

Companies such as General Atomics Aeronautical Procurement have produced a growing line of versatile, reliable, cost-effective, and proven RPAs. Their innovations and high-tech solutions are making waves in the industry, giving rise to aircraft models like the MQ-9B SkyGuardian, MQ-9B SeaGuardian, and the MQ-9A “Reaper”, each with unique capabilities and advanced features.

Drone technology has evolved to support various payload capacities, with heavy-lift drones capable of carrying loads ranging from 5 kilograms to 500 kilograms, expanding their applications in tasks such as cargo delivery and industrial inspections.

Importance Of RPAS In Aviation Industry

The importance of RPAS in the aviation industry cannot be overstated. They play an integral role in our nation’s air defense, providing close-air support, gathering intelligence, and conducting strategic air strikes. Moreover, RPAS are operated by specialized mission aircraft and command flight crews to support personnel accomplish reconnaissance, surveillance, and other missions. They operate mission equipment, systems, and electronic protection (EP) equipment, which greatly enhances their utility and effectiveness.

The global market for Remotely Piloted Aircraft (RPA), commonly known as drones, is projected to reach a value of approximately $129.23 billion by 2027, reflecting the rapid growth and widespread adoption of drone technologies.

Unmanned Aircraft Systems (UAS)

Unmanned Aircraft Systems (UAS), commonly known as RPAs (Remotely Piloted Aircraft), have become an integral part of modern aviation, particularly within the Air Force. These RPAs are designed to operate in non-segregated airspace, necessitating advanced guidance material and technology to ensure safe and efficient integration with manned aircraft. RPA pilots play a critical role in overseeing the operations of these unmanned systems, relying on sophisticated ground stations to control and navigate future RPAs. The seamless coordination between ground stations and RPA operations highlights the evolving landscape of aviation, where unmanned aircraft systems contribute significantly to military and civilian applications.

The average drone’s flight time has improved significantly, with many commercially available drones capable of staying airborne for durations ranging from 20 to 30 minutes, depending on the model and purpose.

Small RPAS Vs. Large RPAS

While all RPAS can contribute significantly to various operations, there is a distinction between smaller and larger RPAS. Both types have unique characteristics and implications in terms of safety, utility, and stakeholder integration.

Integration Of Small RPAS Into National Airspace Systems

Small RPAS are finding increasing application in civilian aviation industry. Various stakeholders such as national aviation authorities (NAAs), including the European Aviation Safety Agency (EASA) and the U.S. Federal Aviation Administration (FAA), air navigation service providers (ANSPs, including EUROCONTROL), airlines, RPAS manufacturers and suppliers, and small RPAS operators are involved in integrating these into national airspace and air traffic control systems.

In 2020, the global drone market saw an annual shipment of over 1.4 million units, showcasing the widespread adoption of drones across consumer, commercial, and industrial sectors.

Involvement Of Stakeholders In Addressing Small-RPAS Safety Issues

These stakeholders are primarily responsible for addressing the operational safety issues associated with small RPAS that can potentially impact manned aviation. This has become an area of growing concern for pilots due to the increased integration of these unmanned systems into national airspace systems.

Safety Performance Of Large RPAS

Large RPAS, on the other hand, whether operated by or for government research, military/intelligence, or corporate flight test missions, have similar histories, levels of advancement, and strong track records in safety. Their mature level of integration into controlled, uncontrolled, and restricted airspace at any altitude means that accidents involving large RPAs rarely affect national airspace systems. Therefore, improving safety performance of larger RPAS may temporarily receive lower priority among these stakeholders.

Drone technology has advanced in terms of range, with some long-range drones capable of covering distances of up to 10 kilometers or more, expanding their applications in various industries, including agriculture, surveillance, and logistics.

Priorities And Challenges In RPAS Operations

The dynamic nature of the aviation industry means that priorities can change over time among stakeholders. Several challenges are associated with the operation of RPAS, some of which are discussed below.

1. Paradigm Shift In sUAS Operations

There has been a paradigm shift from single-UAS visual operations in restricted and controlled airspace, to multi-UAS beyond visual line of sight operations with increasing use of autonomous systems and operations under increasing levels of urban development and airspace usage. This shift poses significant challenges and requires careful management and regulation.

2. Multi-UAS Beyond Visual Line Of Sight Operations

Operating multiple UAS beyond visual line of sight is a complex task that demands advanced control systems and robust communication links. Insufficient mishap (accident and incident) reporting capability for small UAS and the rapid growth of new small UAS applications that have not yet been implemented pose significant risks and challenges.

Drones are employed in agriculture for precision farming, and studies show that drone-based monitoring can lead to an average 25% increase in crop yields, enhancing agricultural productivity and resource management.

3. Insufficient Mishap Reporting For sUAS

There is a lack of sufficient mishap reporting for small UAS. This deficiency in data collection hampers efforts to understand the risks and safety concerns associated with operating these systems, especially when deployed in congested or sensitive airspace.

4. Factors Contributing To The Incident

An example of an incident involving loss of control of a UA occurred over Poole UK. The investigation found that a partial power failure had followed battery disconnection with its consequences not adequately communicated to the pilot. It faulted both the applicable UA User Manual content and the pilot training the absence of sufficient status and detected wind information to the pilot. This incident highlights the importance of proper communication and comprehensive information for remote pilots.

The number of registered drones is increasing globally, with over 1.7 million drones registered with the Federal Aviation Administration (FAA) in the United States alone, indicating the growing popularity of recreational and commercial drone use.
