Communication sits at the centre of the Core Competency Matrix for a reason. It is the link between Leadership and Teamwork and everything else — the mechanism by which decisions are transmitted, situational awareness is shared, and workload is either managed or compounded. And within Communication, this behaviour is the one that most directly determines whether that mechanism works.

The behaviour is named precisely: conveys information clearly, concisely, and accurately. Three qualifiers. They are easy to read past as a standard — a baseline expectation of professional communication. But treat them as that and you miss what they actually are. Clearly, concisely, and accurately are workload management tools. Each one, if neglected, generates work for someone else on the flight deck, on the frequency, or on the ground. Each one, if handled well, removes it.

Three qualifiers — one standard
ClearlyNo ambiguity
Clear communication uses language, tone, and context to ensure the recipient understands the message without ambiguity. This applies equally to verbal, written, and non-verbal communication. In an environment characterised by language barriers, cultural variation, noise, and distraction, clarity is not a courtesy — it is a safety requirement. Say it clearly, say it once.
ConciselyNo excess
Concise communication delivers the maximum amount of information in the minimum number of words. Verbose transmissions force the recipient to extract the relevant content from surrounding noise — which costs cognitive capacity they may not have. Every word that doesn't add meaning subtracts attention. On a busy frequency or in a high-workload cockpit, brevity is not a style preference. It is a safety discipline.
AccuratelyNo doubt
Accuracy means the recipient receives information that is factually correct and complete — nothing essential omitted, nothing incorrect included. Inaccurate information feeds directly into the decision-making process. Decisions built on inaccurate inputs are invalid, and correcting them costs time, increases workload, and degrades situational awareness. Incorrect information is worse than no information.

Why It Matters Beyond the Obvious

The consequences of poor communication in aviation are well-documented and rarely subtle. Misunderstandings between crew members and controllers. Instructions that arrive too late to act on. Information that is technically correct but delivered at a moment of peak workload — and therefore not processed at all. The cascade from a single ambiguous transmission can be long.

But the less obvious consequence is the workload effect. Every unclear message generates a clarification request. Every inaccurate piece of information generates a correction cycle — the wrong action has to be identified, stopped, reversed, and replaced. Every verbose transmission forces the recipient to process more than they need to, at a moment when their capacity is already being consumed by the operation itself. All of this is avoidable cognitive load.

"Communicate the most amount of information in the least amount of words. If you can do this, you are generally achieving the goal of communicating clearly."

This is the deeper point about treating clearly, concisely, and accurately as workload management tools rather than stylistic preferences. A pilot who consistently achieves all three is not simply being professional — they are actively managing the cognitive load of everyone around them. A pilot who routinely falls short of any one of them is generating avoidable work for the whole crew on every transmission.

How to Achieve It

Clarity in practice

The enemy of clarity is assumption — the assumption that what is obvious to you is equally obvious to the recipient. Before transmitting, assess your own message from the receiver's position. Are you using language they will understand without effort? Are you relying on shared context that may not exist? In an environment with language barriers, cultural variation, and noise, clarity requires deliberate construction, not just good intentions.

On the radio, standard phraseology exists precisely to eliminate the ambiguity that informal language introduces. Use it. It is not bureaucratic constraint — it is the accumulated safety learning of decades of aviation, encoded into a form that minimises misunderstanding under pressure.

Key discipline

Before transmitting, assess your own message from the receiver's position. Have you been clear and unambiguous? Would someone with a different cultural background, a different level of situational awareness, or a higher workload understand exactly what you mean? If there is any doubt, restructure before you transmit.

Conciseness in practice

The most useful discipline for conciseness is a simple principle: communicate the maximum amount of information in the minimum number of words. Verbose communication forces the recipient to extract the relevant content from surrounding noise. Concise communication delivers it directly. The discipline to say precisely what is needed, and nothing more, takes deliberate practice — but once it becomes instinctive, it becomes one of the most powerful workload management tools available to a crew member.

Beyond word count: speak at an appropriate rate for the environment. Avoid colloquialisms, slang, and informal language that may not be shared. A transmission that takes twice as long as necessary is not twice as informative — it is twice as demanding of the recipient's attention at a time when that attention is already in short supply.

Accuracy in practice

The rule here is straightforward: if you are in any doubt about what you are communicating, check it before you begin. This applies to performance figures, weather information, clearances, intentions, and any other piece of information that will be used as an input to someone else's decision-making. Do not assume. Do not round. Do not omit the qualification that changes what the number means.

Accurate communication also requires awareness of what you do not know. A message that presents an assumption as a fact, or an estimate as a confirmed figure, is inaccurate in the most operationally dangerous way — because the recipient will act on it with a confidence that the underlying information does not warrant.

The Briefing as a Test Case

The approach briefing is one of the best available tests of this behaviour in practice — because it requires all three qualifiers to be satisfied simultaneously, under a workload that is already building, at a phase of flight where the consequences of failure are greatest.

Approach briefing — applying the standard
Clearly Avoid ambiguous language around intentions, crew roles, and decision triggers. The other pilot must leave the briefing with exactly the same picture as you. If there is any room for interpretation on a go-around trigger, a diversion decision point, or a crew callout, the briefing has not been clear enough.
Concisely An effective briefing is not an information dump. Reading figures aloud that can be independently cross-checked adds length without adding value. Focus on how you intend to operate the aircraft, what the threats are, and what is different from the normal case. That is what needs to be shared — and shared without excess.
Accurately Bring current information. Weather, NOTAMs, chart revisions, aircraft status, minima. A briefing built on outdated or incomplete information creates a mental model in the other pilot that does not match reality — and that divergence will surface at the worst possible moment.

The briefing that satisfies all three — delivered at the right time, built on current information, focused on what matters — is not a long briefing. It is a precise one. The crew emerges from it with a shared mental model, a clear understanding of roles and intentions, and no outstanding questions. That shared model is the foundation on which every subsequent decision in the approach will be built.

The barriers to this behaviour are real and persistent: language, culture, environmental noise, distraction, time pressure, and the assumption that what is clear in your own head is equally clear when transmitted. Each of these requires active management. None of them disappears with experience — but the pilot who has genuinely internalised this behaviour has developed the habit of checking, consistently, whether each message they send meets all three standards before it leaves their mouth.

Say it clearly. Say it concisely. Say it accurately. Then stop talking.
