In aviation, Single Pilot Operations (SPO) refers to a proposal for commercial flights operated with one pilot, where previously two would be required.
Single pilot operations will require improvements in technology including aircraft and cockpit design, and changes to pilot training. Safety must be proved to win acceptance by regulators and the public.
Historically, large aircraft required several personnel on the flight deck, such as a navigator, a flight engineer, and a dedicated radio operator. Improvements in automation, reliability and technology such as autopilot and satellite navigation have enabled modern large aircraft to operate safely with only two pilots on duty.
With further technological improvements, it may be possible safely to reduce crew requirements to one, providing cost savings.
The European Union Aviation Safety Agency (EASA) has been investigating Extended Minimum Crew Operations (eMCO), where an aircraft could be operated by one pilot in the cruise. This would be an initial requirement before single pilot operations might be allowed at a later stage. The research project runs from 2022 to 2025. [1] Airbus and Dassault have expressed interest in eMCO. [2]
Airbus completed its Autonomous Taxi, Take-Off and Landing (ATTOL) project in 2020, demonstrating an autonomous flight with an A350-1000 aircraft. [3] In 2023, Airbus project Dragonfly used a combination of normal and infrared cameras, as well as radar, to assist pilots in various situations. [4] In 2024 Airbus began testing an autonomous aircraft taxi system called "Optimate". [5]
Proposals for Single Pilot Operations are opposed by several pilots' trade unions, including the International Federation of Air Line Pilots' Associations (IFALPA), [2] the American Air Line Pilots Association (ALPA), [6] [7] the European Cockpit Association, [8] and the British Air Line Pilots Association. [9]
In their white paper, ALPA argue that two-pilot operations reduces errors through cross-checking, workload sharing and better decision-making, and provides redundancy in the case of pilot incapacitation. They argue that pilots learn from each other when working together; that pilots are more versatile than aircraft equipment and sensors; and that pilots are better at autonomous decision making. They also raise concerns about cybersecurity. [6]
Avionics are the electronic systems used on aircraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform.
The Airbus A300 is Airbus' first production aircraft and the world's first twin-engine, double-aisle (wide-body) airliner. It was developed by Airbus Industrie GIE, now merged into Airbus SE, and manufactured from 1971 to 2007.
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators because they are involved in operating the aircraft's navigation and engine systems. Other aircrew members, such as drone operators, flight attendants, mechanics and ground crew, are not classified as aviators.
The Airbus A318 is the smallest and least numerous variant airliner of the Airbus A320 family. The A318 carries 107 to 132 passengers and has a maximum range of 5,750 kilometres. Final assembly of the aircraft took place in Hamburg, Germany. It is intended primarily for short-range service.
An autopilot is a system used to control the path of a vehicle without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations.
An air taxi is a small commercial aircraft that makes short flights on demand.
Aeroflot Flight 593 was a passenger flight from Sheremetyevo International Airport, Moscow, Russia, to Kai Tak Airport in Hong Kong. On 23 March 1994, the aircraft operating the route, an Airbus A310-304 flown by Aeroflot, crashed into the Kuznetsk Alatau mountain range in Kemerovo Oblast, killing all sixty-three passengers and twelve crew members on board.
Armavia Flight 967 was a scheduled international passenger flight operated by Armavia from Zvartnots International Airport, Zvarnots in Armenia to Sochi, a Black Sea coastal resort city in Russia. On 3 May 2006, the aircraft operating the route, an Airbus A320-200, crashed into the sea while attempting a go-around following its first approach to Sochi airport; all 113 aboard were killed. The accident was the first major commercial airline crash in 2006. It was Armavia's only fatal accident during the airline's existence.
The Airbus Helicopters H145 is a twin-engine light utility helicopter developed and manufactured by Airbus Helicopters. Originally designated as the BK 117, the H145 is based upon the MBB/Kawasaki BK 117 C1, which became a part of the combined Eurocopter line-up in 1992 with the merger of Messerschmitt-Bölkow-Blohm's helicopter division of Daimler-Benz into Eurocopter. The helicopter was initially named EC145; an updated version, EC145 T2, was renamed H145 in 2015. The helicopter was significantly updated in the 2020s with first a fenestron replacing the traditional tail rotor, followed later by a 5-blade main rotor head.
Airbus Industrie Flight 129 was an Airbus Industrie A330-321 test flight that ended in a crash on 30 June 1994 at Toulouse–Blagnac Airport, killing all seven people aboard. The last test flown was to certify the plane's takeoff capability with a single engine failure. It was the first fatal accident involving an Airbus A330 as well as the first hull loss of the type. It remained the only fatal accident involving an A330 until the crash of Air France Flight 447 on 1 June 2009.
A side-stick or sidestick controller is an aircraft control stick that is located on the side console of the pilot, usually on the righthand side, or outboard on a two-seat flightdeck. Typically this is found in aircraft that are equipped with fly-by-wire control systems.
Flight envelope protection is a human machine interface extension of an aircraft's control system that prevents the pilot of an aircraft from making control commands that would force the aircraft to exceed its structural and aerodynamic operating limits. It is used in some form in all modern commercial fly-by-wire aircraft. The professed advantage of flight envelope protection systems is that they restrict a pilot's excessive control inputs, whether in surprise reaction to emergencies or otherwise, from translating into excessive flight control surface movements. Notionally, this allows pilots to react quickly to an emergency while blunting the effect of an excessive control input resulting from "startle," by electronically limiting excessive control surface movements that could over-stress the airframe and endanger the safety of the aircraft.
The European Cockpit Association (ECA) is a trade union that represents European pilots. It has pursued the improvement of aviation policies to the benefit of its members, and has frequently spoken out in length on topics such as the impact of flight-time limitations on its members, the erosion of aviation safety culture, and the necessity of regulating the emerging subsector of unmanned aerial vehicles (UAVs).
Urban air mobility (UAM) is the use of small, highly automated aircraft to carry passengers or cargo at lower altitudes in urban and suburban areas which have been developed in response to traffic congestion. It usually refers to existing and emerging technologies such as traditional helicopters, vertical-takeoff-and-landing aircraft (VTOL), electrically propelled vertical-takeoff-and-landing aircraft (eVTOL), and unmanned aerial vehicles (UAVs). These aircraft are characterized by the use of multiple electric-powered rotors or fans for lift and propulsion, along with fly-by-wire systems to control them. Inventors have explored urban air mobility concepts since the early days of powered flight. However, advances in materials, computerized flight controls, batteries and electric motors improved innovation and designs beginning in the late 2010s. Most UAM proponents envision that the aircraft will be owned and operated by professional operators, as with taxis, rather than by private individuals.
Flight time or block time is an aviation term referring to the total amount of time spent piloting aircraft, and serves as the primary measure of a pilot's experience. Flight time is defined by International Civil Aviation Organization (ICAO) as "The total time from the moment an aeroplane first moves for the purpose of taking off until the moment it finally comes to rest at the end of the flight", and thus includes time spent taxiing and performing pre-flight checks on the ground, provided the engine is running. It is colloquially referred to as "blocks to blocks" or "chocks to chocks" time. In commercial aviation, this means the time from pushing back at the departure gate to arriving at the destination gate.
Loganair Flight 6780 was a scheduled domestic flight from Aberdeen Airport to Sumburgh Airport in the Shetland Islands, Scotland. On 15 December 2014, the Saab 2000 operating the flight was struck by lightning during the approach, and then plunged faster than the aircraft's maximum operating speed. The aircraft came within 1,100 feet (340 m) of the North Sea before the pilots recovered and returned to Aberdeen. All 33 passengers and crew were unharmed.
Aviation in the European Union and the European Free Trade Association is regulated by the European Union Aviation Safety Agency (EASA). EASA specifies common standards for the licensing of aircraft pilots. EASA does not issue licences, rather licences are issued by member states. However, because the same standards are used, EASA licences are recognised by all member states.
In-flight crew relief, is a term used in commercial aviation when referring to the members of an aircrew intended to temporarily relieve active crew members of their duties during the course of a flight. The term and its role are almost exclusively applied to the secondary pilots of an aircrew, commonly referred to as relief pilots, that relieve the primary and active captain and/or first officer (co-pilot) in command of an aircraft to provide prolonged breaks for rest or sleep opportunities.
A multi-crew pilot licence (MPL) is a pilot licence that permits an aircraft pilot to act as co-pilot of a multi-crew aircraft.
Veronte Autopilot is a family of autopilot systems developed by Embention, a Spanish company specializing in safety-critical avionics for unmanned aerial vehicles (UAVs) and electric vertical take-off and landing (eVTOL) aircraft. Known for its advanced control capabilities, the Veronte Autopilot systems are designed to meet stringent reliability and certification requirements, allowing their integration into both manned and unmanned aircraft.
