11.2 Situational Awareness, Fixation and External Pressure

Situational Awareness: The Big Picture

Situational awareness (SA) is keeping track of everything that matters to the flight, all at once. For an RPAS pilot that means five things:

1. The aircraft — where it is, what it is doing, what mode it is in, whether it is behaving correctly.
2. People — crew, bystanders, the dog that just appeared, the photographer who walked under the drone.
3. Airspace — other traffic, your boundary, controlled airspace, any aircraft you can hear.
4. Weather — wind speed and direction, gusts, changing cloud, temperature (affects battery).
5. Battery — voltage, time remaining, margin to the return-home threshold.

Lose any one of these and you no longer have a safe flight. SA is not a state you reach and keep for free — it is an active process of scanning and updating.

How SA is lost

SA is usually lost in one of three ways:

• Attention tunnelling — you focus hard on one thing (framing the shot, reading a battery number) and everything else drops out.
• High workload — too much happening at once, so you stop scanning and start reacting.
• Distraction — a conversation, a phone call, a problem on the ground pulls your eyes off the drone.

Screen Fixation: The Signature RPAS Trap

The single most common SA failure in drone operations is screen fixation — staring at the controller screen or a monitor and losing visual contact with the RPA and the surroundings. It is easy to do because the screen gives you so much information: live video, telemetry, map, battery, warnings. It feels like you are more in control, not less.

But the screen is a small, low-fidelity slice of the real situation. It does not show the aircraft's true attitude against the sky, the light aircraft you can hear but cannot see on the map, the people who have walked into your landing zone, or the wind change you would feel on your face. CASA's visual line-of-sight (VLOS) requirement exists precisely because the screen is not enough.

The counter: forced VLOS glances

• Look up. Every few seconds, take your eyes off the screen and look at the drone.
• Look around. Scan the sky for traffic, the ground for people, the trees for wind.
• Use the spotter. Your observer/spotter's entire job is VLOS and hazard callouts while you watch the screen.
• Brief the glance. Some pilots use a rhythm: screen, drone, screen, sky, screen, ground. Make it a habit.

If you cannot see the drone with your own eyes, you are not flying VLOS, and you have lost your most reliable SA source.

External Pressure and the Go/No-Go Decision

External pressure is any force from outside the cockpit that pushes you toward a poor go/no-go decision. In RPAS work it almost always sounds like one of these:

• "We've driven three hours, just fly it."
• "The client is on site and they only have a one-hour window."
• "We're losing the light, just get it up."
• "We already paid for the location, we can't come back."

This is sunk-cost and deadline pressure dressed up as operational urgency. It is dangerous because it feels reasonable in the moment, and because it is the one human factor that comes from other people, not from you.

Recognise and resist

• Recognise — when you feel pressure to fly that you would not feel if the client were not there, name it: "this is external pressure."
• Resist — fall back to your pre-decided go/no-go criteria (weather, battery, site, fitness). Those criteria were set when you were calm and clear-headed. Honour them now.
• Pre-brief the client — before the job, tell the client that the pilot alone makes the go/no-go call. This removes the argument on the day.

The Pilot's Absolute Authority to Cancel

The single most important rule in this chapter: the remote pilot's authority to cancel, delay or abort a flight is absolute. It cannot be overridden by the client, the director, the crew, the schedule, or the contract. If you, the pilot, decide the flight is not safe, the flight does not happen.

This is not arrogance — it is responsibility. CASA holds the remote pilot responsible for the safety of the flight. Because the responsibility is yours alone, the authority to stop it must be yours alone too. You cannot be responsible for a decision someone else made for you.

Scenario

You are on a film shoot in a river valley. The call sheet says the drone shot is at 2 PM. At 1:50 PM the wind gusts up to 25 knots, well above your drone's operating limit. The director says, "The light is perfect right now, we won't get another chance, just get it up for two minutes."

The correct response is a calm, clear no, followed by the reason (wind above the operating limit) and an offer to reassess in 15 minutes. The director is applying external pressure; your pre-decided wind limit is your go/no-go criterion; and your authority to cancel is absolute. Two minutes of flight in 25-knot gusts can end in a wrecked aircraft in the river and, worse, in someone on the bank being hurt. The shot is never worth that.

Keeping SA Active

SA is maintained actively. Three habits that work:

• Scan — move your eyes on a rhythm: screen, drone, sky, ground, battery.
• Verbalise — say what you see out loud: "drone at 40 metres, clear above, wind from the west, 60% battery." It forces you to actually check each thing.
• Use the crew — the spotter watches VLOS and hazards; you watch the aircraft and the flight. Brief the roles before takeoff.
