Operations and Safety: Judgment, Physiology, and Emergencies
Most drone accidents are decision failures rather than equipment failures, which is why the FAA tests judgment as its own subject. This chapter covers crew coordination, the aeronautical decision-making process, the five hazardous attitudes and their antidotes, human physiology and vision, and how to handle emergencies, lost link, and maintenance.
Crew Resource Management and Briefings
Crew resource management is the practice of using every available resource, including people, equipment, and information, to run a safe operation. On a Part 107 job the crew may be one person, or it may be a remote pilot in command, a separate person manipulating the controls, and one or more visual observers. Whatever the size, the remote PIC assigns roles and briefs the plan before the aircraft is powered up, so that no one is inventing a response during an emergency. Continuous, unambiguous communication is what turns several people into a crew instead of several individuals standing near a drone.
The remote PIC runs the crew
The remote pilot in command is directly responsible for the operation and assigns duties, sets limits, and makes the final go or no-go call.
14 CFR §107.19Visual observers must be able to see the aircraft
A visual observer must be able to see the unmanned aircraft well enough to know its location, attitude, and direction of flight and to scan for other traffic.
14 CFR §107.33Maintain effective communication at all times
The remote PIC, any person manipulating the controls, and any visual observer must be able to communicate effectively and without delay throughout the flight.
14 CFR §107.33Brief the operation before takeoff
Cover the flight plan, hazards, airspace, weather limits, abort criteria, lost link behavior, and who calls a stop, before anything spins up.
Protect the crew from distraction
Keep bystanders, clients, and phone calls away from the control station during critical phases, since divided attention is a leading cause of loss of control.
Anyone can call a stop
Establish that any crewmember may halt the operation without argument if they see a hazard, and that the remote PIC will support that call.
Aeronautical Decision Making and Risk Assessment
Aeronautical decision making is a structured way to choose a course of action instead of reacting to whatever happens next. Risk is easiest to organize with the PAVE checklist, which sorts hazards into pilot, aircraft, environment, and external pressures. Once a hazard is identified, judge it by how likely it is and how bad the outcome would be, and mitigate anything that lands in the severe or likely range before the flight rather than during it. Structured models such as the three-P method of perceive, process, and perform give you a repeatable loop that keeps working when you are tired or rushed.
Use the PAVE checklist
Sort hazards into Pilot, Aircraft, enVironment, and External pressures, and address each category before launch.
Self-assess with IMSAFE
Check yourself for Illness, Medication, Stress, Alcohol, Fatigue, and Emotion, and ground yourself if any item is unresolved.
14 CFR §107.17Apply the three-P loop
Perceive the hazard, process its severity and likelihood, and perform the mitigating action, then repeat as conditions change.
Name external pressure for what it is
A client waiting, fading daylight, and travel already paid for are pressures that push a pilot toward a flight the conditions do not support.
Mitigate before you launch
Risk is cheapest to eliminate on the ground; once airborne your options narrow to whatever the aircraft can still do.
Set personal minimums
Write down wind, visibility, distance, and fatigue limits stricter than the regulations, and treat them as binding regardless of who is watching.
The Five Hazardous Attitudes and Their Antidotes
The FAA identifies five recurring attitudes that lead pilots into bad decisions, and the countermeasure is to recognize the thought as it happens and answer it with a memorized antidote. The point is not personality analysis; it is interrupting a specific sentence in your head before it becomes an action. Every one of the five feels reasonable in the moment, which is exactly why the antidote has to be rehearsed in advance. Learn all five pairs cold, because they appear on the exam as matched sets.
Anti-authority: do not tell me
The antidote is: follow the rules, they are usually right. This attitude resents regulation and treats procedures as obstacles.
Impulsivity: do something quickly
The antidote is: not so fast, think first. This attitude reacts to the first idea rather than the best one.
Invulnerability: it will not happen to me
The antidote is: it could happen to me. This attitude accepts that accidents occur but assumes they happen to other pilots.
Macho: I can do it
The antidote is: taking chances is foolish. This attitude seeks to prove skill by accepting unnecessary risk.
Resignation: what is the use
The antidote is: I am not helpless, I can make a difference. This attitude surrenders control of the outcome to luck or to someone else.
Physiology, Vision, and Scanning
A remote pilot stands on the ground, but the body still limits performance in ways the exam expects you to know. Fatigue is the most common impairment, and chronic fatigue built over weeks cannot be repaired by a single night of sleep or by caffeine. Dehydration and heat stress build quietly on long outdoor jobs and degrade attention and reaction time before the pilot notices anything wrong. Vision is the other limiting system, because visual line of sight depends on eyes that scan deliberately rather than sweeping across the sky.
Ground yourself when impaired
Do not act as remote pilot, visual observer, or direct participant with a physical or mental condition that would interfere with safe operation.
14 CFR §107.17Treat fatigue as an impairment
Acute fatigue responds to rest, but chronic fatigue from prolonged stress or sleep loss requires an extended break and often medical attention.
Hydrate and manage heat
Dehydration and heat exhaustion reduce concentration and reaction time long before they produce obvious symptoms, so schedule water and shade into long jobs.
Scan in small, deliberate steps
Move the eyes in short regularly spaced steps of about ten degrees and pause briefly at each to let the eyes focus, rather than sweeping continuously across the sky.
Use off-center viewing at night
Night vision relies on the rods at the edge of the retina, so look slightly to the side of an object to see it, and allow roughly 30 minutes for the eyes to adapt to darkness.
Check medications before flying
Many over-the-counter drugs, including antihistamines and sleep aids, impair alertness and coordination, and their effects can outlast the label's dosing interval.
Emergencies, Lost Link, and Maintenance
An in-flight emergency is the one situation where the rules bend, because the remote PIC may deviate from Part 107 to the extent necessary to meet that emergency. That authority comes with accountability: on FAA request you must submit a written report explaining the deviation. Lost link is the most common drone emergency and it is largely handled in advance, by programming a sensible failsafe, setting an accurate home point, and knowing what the aircraft will do when the signal drops. Maintenance closes the loop, since the aircraft must be in a condition for safe operation before flight and any defect found afterward has to be corrected before the next one.
Deviation is allowed in an in-flight emergency
The remote PIC may deviate from any rule of Part 107 to the extent necessary to respond to an in-flight emergency.
14 CFR §107.21A written report may be required after a deviation
If the FAA requests it, the remote PIC must send a written report explaining the deviation.
14 CFR §107.21Program and verify the lost link procedure
Know whether the aircraft will hover, land, or return home on signal loss, confirm the home point is accurate, and check that the return altitude clears obstacles on the path.
Fly it in a condition for safe operation
The remote PIC must not operate an aircraft that is not in a condition for safe operation and must discontinue flight when continuing would be unsafe.
14 CFR §107.15Inspect before and maintain after
Preflight inspection catches loose props, cracked arms, and damaged wiring, and any hard landing or strike calls for unscheduled maintenance before the next flight.
14 CFR §107.49Keep maintenance records
Follow the manufacturer's maintenance program where one exists, build your own schedule where it does not, and log inspections, repairs, and battery cycles.
