The word in this behaviour that carries the most weight is the first one. Acts. Not maintains passively. Not retains awareness by default. Acts — takes specific, deliberate action to keep the mental model accurate and current under conditions that are constantly working to degrade it.
Acts to maintain an accurate mental model and maintains awareness during distractions is distinct from the other SA behaviours in this way. Assessing aircraft state, anticipating contingencies, monitoring for errors — those behaviours are about what you perceive. This one is about what you do to ensure that perception remains possible. It is the maintenance behaviour. The set of active practices that keeps the SA system functioning across the full range of conditions a flight will present.
Verbalise to Share the Picture
Your mental model is invisible to your colleague. What you are seeing, what you are planning, what you are expecting to happen next — none of it reaches the other pilot unless you put it into words. Verbalising is the mechanism by which two separate individual pictures become one shared one. It is the most direct action available for maintaining a shared mental model, and it is available at all times.
This does not mean a running commentary. It means verbalising at the moments that matter — when the model is updating, when a plan is changing, when something unexpected has been observed, when your picture of the situation has shifted and your colleague's may not yet have. A crew that verbalises these updates continuously is a crew whose pictures stay aligned without effort. A crew that works in silence has two individual models that may or may not be consistent — and has no way of knowing which it is until the difference becomes visible in an action that doesn't fit the expected pattern.
The brief is the planned, pre-flight version of the same thing. Before the first sector, there is an opportunity to build a shared model deliberately — to agree on the expected state, the contingencies, the priorities, the decision points. A crew that has briefed well starts the flight with aligned pictures. The maintenance required during the flight is less demanding because the foundation is solid. The shared model already exists. The verbalisation that follows is updating it, not building it from nothing.
Your mental model is invisible to your colleague. The only way to keep both pictures aligned is to externalise yours — at the moments where it is updating, not just when something goes wrong.
Create the Capacity to Maintain It
Maintaining an accurate mental model requires spare cognitive capacity. You cannot verbalise, cannot step back to assess whether the picture is still current, cannot catch the small inconsistency that signals something has changed — if all available capacity is committed to managing the immediate demands of the operation. The actions that maintain SA require headspace. Creating that headspace is a prerequisite, not a luxury.
This is where workload management and situational awareness connect directly. Effective workload management — prioritising correctly, allocating tasks, managing the pace of the operation — is not just an efficiency behaviour. It is an SA maintenance behaviour. The crew that manages workload well enough to maintain spare capacity is the crew that can keep the shared model current. The crew that is consistently saturated is the crew whose model will drift, incrementally and invisibly, until the drift becomes consequential.
The corollary is also true: when SA is threatened — by a non-normal, by a sudden increase in complexity, by an unexpected development that adds demand — the response should include an active reduction in workload wherever possible. Buy time. Extend the timeframe. Reduce the scope of what is being managed simultaneously. The instinct in a demanding situation is often to accelerate — to do more, faster. The correct response for SA maintenance is usually the opposite.
When It Gets Hard — Fall Back to the Basics
There is a hierarchy for exactly this situation, and it has been in aviation for as long as complex operations have existed. When SA is threatened, when complexity is overwhelming, when the model is fragmenting and the pace of events is running ahead of the ability to manage them — Aviate. Navigate. Communicate. In that order.
Not because the other elements do not matter, but because the aircraft has to remain under control before anything else is meaningful. The model can be rebuilt once the aircraft is stable. It cannot be rebuilt if it isn't. Falling back to the hierarchy is not a failure of SA management — it is SA management. It is the deliberate decision to narrow the scope to what is most fundamental, re-establish control, and then expand outward from that foundation.
This requires the discipline to resist the pull of the complex picture and focus on the immediate one. Under pressure, with multiple demands competing for attention, the tendency is to try to manage everything at once. The crew that can recognise that moment and consciously simplify — task the other pilot, defer the non-essential, prioritise the hierarchy — is the crew that creates the space to rebuild the model rather than watching it collapse further.
The behaviour specifically names distractions — not just general workload, but the interruptions that pull attention away from the primary task and create gaps in the model at the moment of the distraction. A cabin call at a critical phase. An unexpected ATC instruction that requires immediate processing. A system alert that demands attention while an approach is in progress.
The discipline required is to manage the distraction without losing the picture. To handle what has to be handled, and then return actively to the monitoring task — not assuming that the picture is still current because nothing dramatic happened during the distraction, but checking. The gap created by a distraction is a gap in the model. Closing it requires going back to confirm what was known before the distraction is still accurate.
Admit It When the Model Is Failing
The most demanding of the active maintenance behaviours is the one that requires the most from the crew environment: admitting when your situational awareness is reducing. Saying clearly that you have lost the picture, that events are moving faster than your ability to track them, that you need time to re-establish before you can manage effectively. This is not a comfortable thing to say. It requires a degree of professional honesty that not everyone finds natural, and a degree of trust in the crew environment that has to be built and maintained deliberately.
This is where Leadership and Teamwork becomes a direct prerequisite for SA maintenance. The safe space — the atmosphere where voicing uncertainty is a normal, professional act rather than a confession of inadequacy — is not a soft requirement. It is the operational foundation on which this part of the behaviour rests. Without it, the admission does not happen. The crew member pushes through instead. The model continues to degrade. And the developing SA breakdown that could have been arrested at the admission stage is allowed to continue.
A crew member who can say they have lost the picture, and a crew environment in which that statement is met with support rather than judgement, is a crew that has access to one of the most effective SA recovery mechanisms available. The admission is the trigger. What follows — the time to re-establish, the support from the other pilot, the slowing of the pace — is the recovery. Both require the same thing to work: a crew that has built the trust and the safety to make it possible.
Saying you have lost the picture is not a failure. It is the most effective SA maintenance action available — and it requires more courage than almost anything else in this behaviour.
