4.2 Reacting to Approaching People & Abort Decisions
Key Takeaways
- When an uninvolved person enters the separation bubble, create horizontal separation with a lateral escape or land in a clear contingency area; climbing alone does not increase horizontal distance.
- Do not overfly approaching people to “get past” them; intentional overflight of uninvolved persons remains prohibited and overflight is a poor recovery geometry.
- If people or events distract you from the aircraft, freeze non-essential camera/ops tasks, re-establish VLOS and attention on the aircraft, then manoeuvre; the remote pilot’s primary duty is safe control of the UA.
- A co-located observer may maintain the direct visual function and airspace scan where the rules allow, including FPV, but clear communication and the remote pilot’s responsibility for safe control remain.
- Abort the mission when separation, segregation, VLOS, weather, performance, or attention cannot be restored promptly—completing the shot is never worth a ground-risk or attention failure.
The Separation Bubble Is Dynamic
Even excellent site selection fails occasionally: a dog-walker appears from a side gate, a delivery van stops inside your contingency patch, school children cut across the closed car park you thought was empty. A2 competence is judged as much by mid-flight reaction as by pre-flight planning. The regulation’s person-distance floors and the ban on intentional overflight of uninvolved persons do not pause because the shot is almost finished.
Treat the separation bubble as a moving volume around every uninvolved person. When that volume and your aircraft’s position conflict, you have a short list of lawful, professional responses:
- Move the aircraft to restore at least the required horizontal separation (and preferably 1:1 / extra margin).
- Land in a clear contingency area if continuing flight cannot restore separation quickly and safely.
- Pause or abort the mission if people keep entering the area or segregation has collapsed.
What you do not do is press on, overfly them, or argue that they “should not be there.” On the exam, options that prioritise client delivery over restoring separation are wrong.
Restore Horizontal Distance: Lateral Escape or Land
The usual recovery is a lateral movement that increases horizontal distance, or a landing in a clear contingency area. A climb may help clear an obstacle or improve control geometry, but climbing alone does not increase horizontal separation:
- Lateral move away from the person’s track—do not mirror their path into a corner.
- Climb only as a supporting action when it is safe and useful for obstacle clearance or control; do not count it as horizontal separation, and never climb into an overflight path.
- Reduce speed / confirm low-speed mode if you were already using it and energy management helps you stop short—but mode does not excuse being inside the floor.
- Reposition the whole task volume further into the segregated zone if one still exists.
Decision sketch
| Observation | Preferred first actions | Avoid |
|---|---|---|
| Walker enters 30 m bubble (UK2 normal) | Lateral escape; climb only if separately useful and safe; hold outside ≥30 m (and 1:1) | Fly over them to the next waypoint |
| Person enters ~8 m while you are at 5 m privilege | Immediately increase horizontal distance or land; re-check whether 5 m is still justified | Hover and film them “carefully” |
| Crowd forming on multiple sides | Land or climb out to a holding point, then abort or re-plan | Thread between groups |
| Person walks toward contingency pad | Choose alternate landing area early | Descend onto the pad anyway |
Remember horizontal is the regulatory axis for the 30/5/50 m floors. Gaining height alone while remaining directly above someone does not create compliance—and intentional overflight is banned in A2 regardless of height.
Do Not Overfly to “Get Past”
A persistent practical and exam trap: the pilot is on one side of a path, the next camera angle is on the other, and a few people are on the path. The temptation is a quick transit over them at height. That is intentional overflight of uninvolved persons in A2 Near People operations—it is not allowed as a transit convenience.
Better options:
- Wait until the path clears and segregation returns.
- Fly a long way around while keeping horizontal floors.
- Land, walk the kit, relaunch from the far side inside a segregated area.
- Redesign the shot list.
“They are only under me for two seconds” is not a legal or syllabus answer. Two seconds of overflight is still overflight.
Freeze Camera and Secondary Tasks When Distracted
Near People flying raises workload: framing, app menus, client talk, radio, and the aircraft’s energy state compete for attention. If an approaching person or any anomaly pulls your eyes and mind off the aircraft:
- Stop non-essential camera work — pause recording adjustments, stop reframing, ignore the client’s “one more angle” until the aircraft is safe.
- Re-establish VLOS and a stable flight condition (hover or gentle climb in clear air if appropriate).
- Solve the people / hazard problem (move, land, abort).
- Only then resume the creative or commercial task.
The A2 theory link is direct: VLOS and attention management are part of safe Open-category flying. Losing visual contact with the unmanned aircraft while you argue with a passer-by or tweak ND filters is a primary failure mode. A properly briefed, co-located unmanned-aircraft observer may maintain direct unaided visual contact and the airspace scan where the Open rules allow, including during FPV. The observer must communicate clearly, while the remote pilot remains responsible and able to act immediately.
Communicate with Involved Crew
When you have a spotter, marshal, or assistant, use them:
- Agree call-outs before flight (“person left path,” “pad clear,” “land now”).
- Give the spotter responsibility for approach routes you cannot watch continuously while flying.
- Confirm hand signals or radio brevity so you are not in a long conversation mid-hover next to people.
- Make clear that anyone can call a safety stop; ego does not outrank separation. If the observer is maintaining the direct visual function, remain co-located and use unambiguous traffic and stop calls.
Crew communication is an operational mitigation. It fails if the observer loses direct unaided contact, cannot scan the airspace, is not co-located, or cannot communicate promptly. FPV remains lawful only within the permitted observer arrangement; it is not a route to extended-range BVLOS.
When to Abort the Mission
Abort means ending the airborne task (usually by landing safely as soon as practicable) because continuing would breach rules or unacceptably raise risk. Strong abort triggers in A2 Near People work include:
- Uninvolved persons repeatedly enter the buffer and segregation cannot be restored.
- You cannot maintain VLOS or attention on the aircraft.
- Weather or performance degrades below your go criteria (gusts, battery sag, GNSS hop, control lag).
- An airspace or ground emergency appears (manned aircraft, emergency services activity, site evacuation).
- You discover the site plan was wrong (FRZ, unexpected assembly of people, obstacle).
- Low-speed 5 m conditions fail mid-flight—you must open distance to at least the normal floor (30 m for UK2) or leave the area; you do not “hope” the mode still justifies 5 m.
Abort is not failure of competence; refusing to abort when separation cannot be held is the competence failure. Commercial pressure is a classic distractor on scenario questions: the client paid for golden-hour light; the correct answer is still land and rebook if people fill the park.
Linking Reaction to VLOS and Chapter 3 Numbers
Use the same hierarchy mid-flight that you used in planning:
- No intentional overflight of uninvolved persons.
- Meet the statutory floor for mark and mode (30 / 5 / 50 m as applicable).
- Apply 1:1 and extra margin when height, energy, or reaction time demand more.
- Protect VLOS and pilot attention while you manoeuvre.
- Land or abort if 1–4 cannot be maintained.
Worked reactions
Scenario 1 — Single walker, UK2 normal mode, 25 m AGL. Horizontal distance falls toward 20 m. You lateral-translate away and climb slightly, restoring ≥30 m (1:1 would want ≥25 m; floor dominates at 30 m). You do not cross above the walker. Brief the spotter to watch the path.
Scenario 2 — Low-speed 5 m privilege, child runs toward the hover. Immediately increase horizontal distance or land in the contingency zone away from the child. Do not descend toward them “to land at their feet.” Reassess whether any further 5 m work is justified; one intrusion may mean segregation has failed for the day.
Scenario 3 — Client waves you over their head for a selfie. Refuse. They may be involved only if briefed and accepting risk and you still obey Open rules for the operation; encouraging overflight of people is the wrong culture and often the wrong legal call for uninvolved-style geometry. Keep the aircraft clear; land and re-brief if needed.
Scenario 4 — The aircraft passes behind a building while attention is divided. That is a VLOS break. Use the pre-planned lost-visual procedure, stop extending the flight, communicate with the observer if present, and recover or land only through a safe known path. Do not continue a map-only wander near people.
Attention Management Checklist (Mid-Flight)
- Eyes and scan: aircraft → people/obstacles → instruments/app → back to aircraft.
- One primary pilot; do not dual-wield complex camera moves and public management without capacity.
- If workload spikes, simplify: hover, gain space, hand camera framing back to defaults.
- After any conflict with people, reset the mental plan before the next manoeuvre.
Memory Hooks for Section 4.2
- Restore distance or land — first response to bubble intrusion.
- Never overfly to transit past uninvolved persons in A2.
- Freeze secondary tasks when attention is compromised.
- Crew calls help; pilot or permitted observer maintains direct visual contact.
- Abort early when segregation or attention cannot be recovered.
