The Skill That Has to Be
Ready When You Need It

The default on a modern airliner is automated flight. The autopilot holds the path, the autothrottle manages the energy, the flight management system sequences the constraints. That is not a concession to convenience — it is the operationally correct position. Automation used well reduces cognitive load on both pilots, frees capacity for monitoring, and allows the crew to manage the operation at a level above the immediate demands of flying the aircraft. The industry, regulators, and the data from decades of commercial operations all support this conclusion. For most of the flight, most of the time, the automation should be doing the flying.

But the Minimum Equipment List does not prohibit flight without an autopilot. Which means there will be moments — planned or otherwise — when the aircraft is being flown manually, and everything that would otherwise be managed by the automation falls back to the crew. Managing flight path and energy to achieve optimum operational performance whilst managing other tasks is the behaviour that covers this territory. It asks what manual flying actually demands of a crew, and how a professional manages those demands without allowing either the path or the tasks to suffer.

What Manual Flight Actually Costs

The workload cost of manual flight is real and it falls on both pilots. For the pilot flying, the aircraft demands continuous active input — control deflections, power adjustments, trim management, instrument cross-check. None of this is automatic. Every parameter that drifts requires a correction, and every correction requires attention that is taken from somewhere else. The cognitive bandwidth available for other tasks — programming, checklists, ATC, situational awareness — is narrowed by the simple fact of having to fly the aircraft with your hands.

For the pilot monitoring, the workload cost is different but equally real. The monitoring pilot's role expands when the aircraft is being flown manually. The automation is not cross-checking the path. No flight director is commanding the correct pitch attitude. No autothrottle is holding the target speed. The monitoring pilot has to provide the layer of oversight that the automation would otherwise supply — calling deviations, confirming energy state, watching the instruments that the pilot flying cannot divide their attention to cover. This is not a passive role. It is continuous and demanding.

The consequence is a reduction in overall crew spare capacity — the bandwidth available for monitoring the wider operation, anticipating what comes next, and managing the unexpected. This is not a reason to avoid manual flight. It is the reason to choose the moment for it carefully, and to manage it actively when it is happening.

The Automation Spectrum

Manual flight is not a binary state. Between full autopilot engagement and raw data flying lies a spectrum of automation levels, each with a different workload profile. Understanding that spectrum — and selecting the appropriate point on it — is itself an expression of this behaviour.

Manual flight with the flight director active represents the most workload-efficient form of hand flying available. The flight director provides commanded pitch and roll inputs, reducing the pilot's cognitive task to following the guidance rather than computing it. The energy management — the judgement of how much pitch changes speed, how speed affects climb rate, how the profile is tracking against the constraint — is still the pilot's responsibility, but the immediate task of knowing where the nose should be is shared with the system. Workload is higher than with the autopilot engaged, but substantially lower than raw data flying.

Raw data flying — no autopilot, no flight director — demands the full set of manual skills. The pilot must compute all guidance internally, cross-reference the instruments continuously, and manage energy state from first principles. In benign conditions with low task demands elsewhere, this is achievable and is precisely the kind of deliberate practice that maintains currency. In demanding conditions with concurrent tasks, it requires a level of proficiency that must be genuinely current, not theoretically remembered.

Tasks That Don't Stop

The difficulty with this behaviour is that the tasks do not pause because the aircraft is being flown manually. ATC still issues instructions. Checklists still need to be completed. The FMS still needs managing. Weather still needs to be assessed. All of the concurrent demands of line flying continue, and they arrive into a crew whose available capacity is already reduced by the demands of the manual flying itself.

The management of this is primarily a workload management discipline. Tasks need to be sequenced around the demands of the manual flying rather than competing with them simultaneously. When the pilot flying is hand-flying through a workload-demanding phase, the pilot monitoring absorbs the tasks that can be absorbed. The tasks that cannot be deferred are communicated clearly, handled efficiently, and closed before either pilot's attention migrates from the path for long enough to allow a deviation to develop.

Briefing the manual flying intention before it happens creates the framework for this management. When the crew has agreed that the approach will be hand-flown with the flight director, has discussed who will handle ATC during the descent, and has identified the points at which the pilot flying will need the monitoring pilot to hold all other tasks — that crew enters the manual phase with an agreed plan. The tasks still arrive. But they arrive into a crew that has already thought about how to handle them.

The Non-Normal Dimension

There is a version of this behaviour where the choice to fly manually is not a choice at all. Autopilot failures, hydraulic events, electrical degradation — a range of non-normal situations can remove automation that the crew was depending on, at a moment when the workload of the abnormal itself is already demanding. The aircraft still needs to be flown. The path still needs to be managed. The energy state still matters. And the non-normal procedure still needs to be worked.

In that moment, the manual flying skill either exists at the level required or it does not. There is no warm-up period. There is no opportunity to practise before the situation demands the skill in earnest. The crew is flying the aircraft manually, managing a non-normal, and the task sequencing challenge described above is now operating in the least forgiving environment it can occupy.

This is the core argument for maintaining manual flying currency as a professional discipline — not for its own sake, not as a preference, but because the MEL keeps the possibility open and the operation demands the readiness. The skill maintained through deliberate practice in benign conditions is the skill available in adverse ones.

Optimum Performance Under Manual Control

The behaviour specifies optimum operational performance — not simply adequate performance, not just keeping the aircraft within limits, but performance that is optimised for the operational context. In manual flight, that standard requires the energy management skills that automation ordinarily handles automatically: understanding how the aircraft's speed and altitude interact as power is managed, anticipating how the profile will track against upcoming constraints, recognising when the current trajectory will not meet the required crossing restriction and making the correction early enough to do it smoothly.

Optimum performance under manual control looks effortless from the outside for the same reason that automation management does — because the pilot is ahead of the aircraft, not reacting to it. The corrections are small because the deviations are caught early. The energy state arrives at constraints because it was managed from further back. The tasks are handled because the pilot flying is not saturated by the demands of the path itself. That is the standard this behaviour points towards — and it is only achievable when the underlying manual skill is genuinely current.
