Before getting into planning techniques, it is worth understanding the baseline requirements. CASA requires fuel carried for flight to be suitable, uncontaminated and of the correct type. Incorrect fuel, or contamination entering the system, can create problems long before quantity becomes an issue.

Simple habits remain important. Use reliable fuel sources, check fuel quality and drain tanks as required before flight and after refuelling.

The Visual Flight Rules Guide remains a useful plain English reference. CASR 91.465 deals with fuel quality and suitability, while the Part 91 MOS sets out reserve fuel requirements.

For most VFR operations in aircraft below 5,700 kg, pilots are required to carry a minimum of 30 minutes final reserve fuel. That does not mean planning to land with 30 minutes remaining. Minimums are exactly that.

Reserve fuel exists for circumstances that were not part of the original plan. Unexpected headwinds, weather deviations, holding, traffic delays or a runway closure can quickly reduce your available margin. Reserve fuel should not be treated as usable trip fuel.

Plan to arrive with it intact. If your fuel situation starts becoming uncomfortable, speak up early. A timely call can often prevent the situation from becoming critical. If required, declare an emergency.

Weather has a direct impact on fuel planning. Headwinds increase flight time and reduce range. Weather avoidance may necessitate the need to travel further. Conditions at destination may require holding or diverting. That means poor or uncertain weather generally requires more margin, not less. Sometimes the safest fuel decision is simply making an earlier stop and topping up.

Running out of fuel, or becoming critically low on fuel, is reportable. But reporting is not the real consequence. Fuel exhaustion can lead to an off field landing, aircraft damage, injury or worse.

In many cases, these events are avoidable through better planning, earlier decisions and maintaining comfortable margins. Fuel planning is not paperwork. It is one of the simplest ways to protect the flight, protect the aircraft and make sure everyone gets home safely.

When aviation events occur, our conversations naturally focus on what happened and how to prevent it happening again.

We review weather, qualifications, aircraft performance and operational decisions. We look for lessons, identify contributing factors and consider what could be done differently in future. That process matters. Learning from events is one of aviation’s greatest strengths and has shaped many of the improvements we now take for granted.

But there is another side of aviation events that receives far less attention. Not what happened to the aircraft, but what happened afterwards.

Aviation events can affect more than those directly involved. Family members, friends, witnesses, instructors, emergency responders and flying communities may all experience events differently and carry them in different ways.

New Zealand pilot Pete Blake has previously reflected on the impact of witnessing the fatal accident of a close friend and colleague and the effect it had on him afterwards. What stands out is not discussion about aircraft performance or technical causes. It is the reminder that aviation events do not always end when the aircraft stops moving.

As pilots, we naturally think about risk in terms of ourselves and the operation we are conducting. Am I current? Am I qualified? Is the aircraft serviceable? Do the conditions support the flight?

These are important questions and they should remain central to good decision making. But aviation decisions are rarely carried by one person alone.

Every flight also affects the people around us. The people expecting us home, the people who trust our decisions and sometimes the people who may unexpectedly become part of the event.

This is not about avoiding challenge or suggesting aviation should become risk free. Aviation has always involved making decisions in dynamic environments and accepting that uncertainty can never be completely removed.

But preserving margin is not only about protecting the aircraft. Sometimes it protects opportunities. The opportunity to continue flying. The opportunity to share aviation with others. The opportunity to come back tomorrow.

Perhaps there is value in occasionally asking one additional question alongside all the others. Not only whether I am comfortable accepting this risk. But who else may be accepting it with me.

Because when things do go wrong, the impact rarely stops with the aircraft. It doesn’t end there.

Airspace related occurrences continue to highlight the importance of preparation, situational awareness and sound decision making. Throughout the year, RAAus has seen an increase in airspace related occurrences, including airspace infringements involving entry into controlled airspace. These events rarely involve pilots intentionally operating where they should not.

More often, they involve changing conditions, increasing workload, reduced situational awareness, or assumptions that the original plan still works.

For most RAAus pilots, controlled airspace is generally not available as part of normal operations unless additional pilot and aircraft requirements are met.

That makes understanding where controlled airspace exists, and planning to remain clear of it, an important part of every flight.

Before every flight, take time to consider:

• Controlled airspace relative to your route
• Aerodrome activity and likely traffic flows
• Prohibited, Restricted or Danger Areas
• Relevant NOTAMs
• Terrain and weather impacts
• Alternates if conditions change

Where practical, avoid planning directly along boundaries and leave yourself margin. Airspace awareness is not about memorising charts.

It is understanding enough about the operating environment that your position never becomes a surprise.

Electronic Flight Bags have changed the way many of us plan and operate. Used well, they can improve situational awareness, support pre flight planning and reduce workload. But they still rely on pilots understanding what they are looking at.

Airspace is more than a line on a screen. Vertical limits, airspace status, operating hours and surrounding airspace all matter. Technology should support decision making, not replace it.
