Decision-Making, Risk Matrix and Operational Worksheets

Human factors become visible in decisions

Human performance is not just a list of personal limitations. It shows up in ordinary decisions: launch now or wait, continue or land, trust the plan or update it, accept a client request or hold the line.

The remote pilot's job is to make those decisions deliberate. That means noticing pressure, naming the risk, choosing a control and leaving a decision trail that another competent person could understand later.

• If the crew is rushing, slow the operation down.
• If the plan no longer matches the site, update the plan before launch.
• If the risk control is vague, the operation is not yet controlled.
• If the decision cannot be explained simply, pause and re-brief.

Pressure creates decision traps

Most poor decisions do not feel careless at the time. They often feel efficient, loyal, confident or helpful. That is why pressure should be treated as a threat in its own right.

Common traps include confirmation bias, plan continuation, risky shift and screen fixation. The practical countermeasure is to give the crew a short pause point where someone asks what has changed and whether the operation still has margin.

• Confirmation bias: only noticing information that supports the plan you already wanted.
• Plan continuation: pressing on because stopping would be inconvenient.
• Risky shift: a group becoming more comfortable with risk than any one person should be.
• Screen fixation: losing the aircraft, site or airspace picture because the display is absorbing attention.

Use a risk matrix as a conversation starter

A risk matrix is not magic. It will not make a bad operation safe by colouring a square green. Its value is forcing the crew to discuss likelihood, consequence, controls and the residual risk after those controls are applied.

The strongest remote pilot habit is plain wording: this hazard could cause this outcome, so we will apply this control, and our final decision is go, modify, delay or stop.

• Likelihood asks how credible the event is in this operation, not in aviation generally.
• Consequence asks what could happen if the hazard is not controlled.
• Controls should reduce likelihood, consequence or exposure.
• Residual risk is the risk left after the control is actually in place.

Turn TEM into a live worksheet

Threat and error management is easiest to teach as a loop. Identify the threat, choose a countermeasure, trap errors early, recover before the aircraft state becomes unsafe, then learn from the job.

In a remote pilot briefing, this can be a short worksheet rather than a long speech. The crew should know the top threats, the stop words, the recovery action and who has authority to call a hold or landing.

• Threat: what can push the job away from the plan?
• Countermeasure: what will we do before that happens?
• Error trap: how will the crew notice and call it early?
• Recovery: what action returns the operation to a controlled state?

Give every crew member a useful voice

Crew coordination is a control only when the crew knows what to say and when to say it. An observer who is unsure whether they are allowed to interrupt is not an effective observer.

The pre-flight brief should give plain callouts for traffic, people, loss of visual contact, battery concerns, weather change, boundary drift and confusion. Closed-loop communication then confirms the message was heard and acted on.

• Use short calls: stop, hold, land, traffic, people, visual lost, battery, boundary.
• Acknowledge critical calls so the sender knows the message landed.
• Re-brief after any material change instead of relying on assumptions.
• Protect assertive calls from rank, customer pressure or embarrassment.

Use personal minimums before the legal minimums

Legal limits are not always enough for a particular pilot, aircraft, crew or site. Personal and operational minimums help prevent a pilot from negotiating with the limit while under pressure.

Examples include maximum gust spread, minimum battery reserve, maximum distance for reliable VLOS, minimum crew numbers for complex sites, a maximum number of concurrent tasks, or a rule that any lost-visual event triggers an immediate hold or landing.

• Write personal minimums before the job, not during the hard moment.
• Make the minimum measurable where possible.
• Brief the trigger and the action together.
• Tighten the minimum when fatigue, heat, glare, poor visibility or complex airspace increases workload.

Debrief the decision, not just the flight

A short debrief closes the learning loop. It should ask what changed, what was missed, which controls worked, which calls were useful and what the next operation should do differently.

This is study guidance, not legal advice. Use current CASA guidance, operator procedures and aviation reviewer advice when setting risk matrices, operational thresholds and reporting requirements.

• What was the strongest threat today?
• Which control gave us the most safety margin?
• Where did workload rise?
• What should be changed in the JSA, checklist or brief before next time?
