Single-Pilot Operations

Single-Pilot Operations refers to proposals by aircraft manufacturers, airlines, and some regulators to reduce the flight deck crew of commercial transport aircraft from the current standard of two pilots — captain and first officer — to a single pilot for portions of flight, with the eventual goal of fully autonomous commercial operations. SPO has emerged as a serious industry and regulatory discussion topic driven by a projected global shortage of commercial airline pilots, the declining cost of advanced automation, and the demonstrated reliability of autopilot and fly-by-wire systems on modern long-haul aircraft, which fly under autopilot for the vast majority of each flight.

What Is Single-Pilot Operations?

Commercial aviation transitioned from three-person crews (captain, first officer, flight engineer) to standard two-person crews in the 1980s as automation replaced the need for a dedicated systems engineer. SPO proponents argue that a similar transition to one pilot — or a remote co-pilot on the ground — is technically feasible given the reliability of modern autopilot systems, the performance of AI-based monitoring tools, and the low frequency of situations that genuinely require simultaneous coordinated action from two pilots. Opponents, including pilot unions and many safety researchers, argue that the two-pilot standard exists specifically because aviation has engineered it into current aircraft designs, training standards, ATC communication protocols, and emergency procedure logic, and that the 1-in-a-million scenarios that require genuine two-pilot coordination are precisely the ones where human redundancy is most valuable.

How It Works in Practice

EASA published a Concept Paper on Extended Minimum Crew Operations (eMCO) in 2020 and followed with further research documentation exploring what regulatory framework would be needed to permit one pilot to rest in a crew rest compartment during cruise phase while the other pilot monitors, with automatic systems performing many functions. This "one pilot in seat" concept for cruise phase is distinguishable from full single-pilot operations but represents a stepping stone toward them. The Airbus "DragonFly" autonomous landing system, tested on an A350, demonstrated fully automatic taxi, takeoff, flight, and landing in 2019. Reliable automation of taxi and takeoff — the phases pilots consider most cognitively demanding — is considered a necessary precondition for SPO. No regulatory authority has yet approved SPO for commercial passenger operations, and no airline has announced concrete plans to operate single-pilot commercial flights.

Why It Matters

The debate over SPO is one of the defining safety policy questions facing commercial aviation in the coming decade. Proponents note that approximately half of all commercial aviation accidents involve both pilots making simultaneous errors rather than one catching the other's mistake — a phenomenon sometimes called "collaborative error." Opponents counter that the cases where the second pilot saves the flight — a captain incapacitated by a heart attack, a first officer catching a captain's automation mode confusion, a crew jointly diagnosing an ambiguous system malfunction — are the exact scenarios that cannot be eliminated by better automation and that make two-pilot redundancy worth the cost. The Boeing 737 MAX accidents themselves, paradoxically, have both advanced and retarded the SPO discussion: they demonstrated the catastrophic consequences of inadequate human-machine interface design in existing dual-crew aircraft, but they also reminded regulators of the complexity of software-driven failures that exceed single pilots' cognitive bandwidth under stress.

Key Facts and Figures

• The global commercial aviation pilot shortage is projected to reach 80,000 pilots by 2032 and 170,000 by 2040, according to IATA and Boeing forecasts.
• The Airbus DragonFly project successfully demonstrated fully autonomous flight including takeoff and landing on an A350 in tests published in 2019–2020.
• EASA's eMCO concept paper (2020) proposed a regulatory pathway for cruise-phase single-pilot monitoring with defined automation requirements.
• No commercial aviation authority has yet approved single-pilot commercial passenger operations under any framework.
• Cargo operators are viewed as the likely first adopters of SPO given reduced passenger risk sensitivity.
• The FAA's Part 121 regulations currently require at least two pilots for all scheduled commercial operations, a requirement that would require formal rulemaking to change.
