Follow the checklists. Adhere to the SOPs. Your references are your suite of company and manufacturer manuals. Comply with ATC instructions. Operate within regulatory requirements. This is the professional standard — the accumulated product of decades of operational experience, incident investigation and safety thinking, encoded into procedures that remove individual variation from the areas where individual variation is most dangerous.
And then, in every operations manual, a clause that acknowledges what the procedures cannot do.
That sentence — its specific wording varies by operator, but its intent is universal — asks the crew to do something that their entire professional formation has been directed against. To abandon the structure. To act outside the prescribed. To make a judgment call in a situation that, by definition, the procedures did not anticipate. Improvises when faced with unforeseeable circumstances to achieve the safest outcome is the behaviour that describes what happens when that clause is invoked — and it is the most demanding behavioural ask in the entire competency framework.
When Time Is Available
The fortunate version of this behaviour is the one where the unforeseeable circumstance develops slowly enough for a deliberate process. The situation is novel — the procedures don't cover it, or the procedures as written would produce an outcome the crew can see is not the safest one available — but time is available to think, to involve the crew, to work through the options before committing.
In this version, the full suite of behaviours is available. A structured problem-solving framework — TDODAR, FORDEC — can be applied. The diagnosis can be properly established. Options can be generated collaboratively. The benefit versus risk assessment can be conducted with adequate time for consideration. The decision, however unconventional, can be reached through a proper process and communicated clearly before it is executed.
This is also the version that most closely resembles training. Simulator scenarios are designed with enough structure for the crew to work through them systematically. The unforeseeable element is introduced, but the time available is usually sufficient for deliberate problem-solving. The reality of the truly unforeseeable situation — the one that arrives compressed, without warning, with no runway of time in which to apply a framework — is harder to replicate and harder to prepare for directly.
The fortunate version gives you time to think. The more likely version doesn't. And the difference between them determines what the crew is actually drawing on when they act.
When Time Is Not Available
The unforeseeable situation, by its nature, tends not to arrive with adequate warning. It arrives compressed — in the middle of a demanding phase of flight, often compounding an already complex situation, with the window between perception and required action too narrow for a deliberate structured process. The framework cannot be fully worked through. The options cannot be carefully evaluated. The decision has to be made now.
This is the version where the question of what the crew is drawing on becomes operationally critical. It is not instinct in the primitive sense — not a reflex disconnected from knowledge and experience. What the crew is drawing on in compressed time is the distilled product of everything built across years of disciplined operation.
The deep, internalised knowledge of the aircraft and its systems — not the knowledge that can be recalled under calm conditions, but the knowledge that has been applied repeatedly enough to be truly automatic. The understanding of what safe looks like across every dimension of the operation: what the acceptable flight envelope is, where its boundaries are, what the aircraft will and will not tolerate. The thousands of hours of normal operations in which the standards were maintained, the procedures were followed consistently, and the baseline of professional behaviour was demonstrated sector after sector.
That baseline is what makes rapid improvisation possible. The commander who knows exactly what right looks like is the commander who can recognise, in the fraction of available time, what the closest approximation to right looks like in a situation right was never designed for. The decision is not a guess. It is the product of a professional formation so deeply embedded that it operates without the deliberate process that time would otherwise allow.
In time-compressed improvisation, the threat and error management evaluation that would ideally precede the decision has to happen faster than deliberate cognition allows. What makes this possible is that large elements of that evaluation have already been performed — in the briefing, in the continuous SA maintenance of the flight, in the habit of monitoring that has been running throughout the operation.
A crew that arrives at the unforeseeable circumstance with a current shared mental model, accurate situational awareness, and the full picture of the operational state — fuel, terrain, traffic, aircraft condition, crew state — is a crew that has already done much of the threat evaluation that compressed time cannot now accommodate. The situation is novel. The context it sits within is known. And it is the context that determines whether the improvised response is safe.
Knowing What Good Looks Like
There is a question implicit in this behaviour that is rarely asked directly: what qualifies a crew member to improvise safely? The operations manual grants the authority. It does not describe the capability. And the capability is not simply seniority, or hours, or type experience. It is something more specific.
It is knowing what good looks like. Across the aircraft. Across the operation. Across every phase of flight and every combination of conditions the crew has encountered. The commander who can improvise safely in an unforeseeable situation is the commander who has such a clear and accurate picture of what safe, stable, within-limits flight looks like that departing from procedures does not mean departing from that picture. The improvised response is still aimed at the same target. The route to it is simply one that the procedures did not chart.
This knowledge is not acquired in the simulator. It is built across years of disciplined line flying — of precise SOP execution, of maintained standards, of consistent professional behaviour applied to ordinary sectors where the consequences of variation were manageable. The simulator teaches the response to the anticipated. The line builds the foundation from which the unanticipated can be managed.
The Foundation Is Everything
The closing argument is the one that connects this behaviour back to everything in the framework — and to everything in the gap between structured training events where the framework's behaviours are actually built.
The commander who can improvise safely is not the most creative under pressure. It is the most disciplined when pressure is absent. The SOPs followed precisely in routine operations. The standards maintained when no assessor was present. The knowledge kept current. The SA maintained through demanding sectors and quiet ones alike. The crew led with clarity and consistency. The procedures executed with discipline, not because the consequences of imprecision in that moment were significant, but because the habit of precision is the one that will be available when they are.
Safe improvisation is not a departure from the professional standards that govern normal operations. It is the expression of those standards in a situation where the normal framework for expressing them does not exist. You cannot improvise safely from a weak baseline. The depth of knowledge, the quality of situational awareness, the reliability of professional judgment — all of it has to be present before the unforeseeable circumstance arrives, because there will be no time to assemble it once it does.
The commander who can improvise safely is the one who has been most disciplined when improvisation was not required. Safe improvisation is not a departure from professional standards. It is their deepest expression.
