Look through drone accident cases and the cause is more often a gap in procedure than a defect in the equipment. Battery condition was not checked. Nobody re-checked the airspace at the site. The operator changed and there was no handover. If you fly drones commercially, the answer is not to lean on individual skill but to build a safety management system that runs to the same standard whoever goes out that day.
Start by treating the legal procedures as ongoing maintenance
Safety management brings aircraft inspection to mind first, but for a business it is the paperwork that collapses soonest. Each of the following needs a named owner and a review cycle.
- Insurance: renewal date, whether cover meets the statutory minimum of at least KRW 150 million per person for bodily injury and KRW 20 million per case for property damage, and the list of aircraft named on the policy
- Device registration (기체 신고): registration status and marked registration numbers for every aircraft held, plus cancellation filings for aircraft disposed of or transferred
- Business registration: whether changes to registered particulars have been updated
- Operator certificates (조종자 증명): the class and validity held by each person. These are administered by the Korea Transportation Safety Authority (TS); Class 1 requires 20 hours of flight experience, Class 2 requires 10 hours and Class 3 requires 6 hours, while Class 4 is obtained by completing online training.
Insurance, device registration and business registration are interlocked in that order — insurance first, then registration, then the business licence — so when one lapses, everything downstream of it wobbles too.
Fix the pre-flight check in writing
The next thing to build is the checklist. A procedure that exists only in someone's head is the first thing dropped on a busy site.
- Documents: device registration status, operator certificate class, flight approval and the Ministry of National Defense aerial photography permit, insurance validity period
- Airspace and environment: airspace classification for the flight area, the 150m altitude limit, nearby buildings and power lines, and the movement paths of people and vehicles
- Weather: wind speed and gusts, precipitation, visibility, and battery performance loss with temperature
- Aircraft: propeller damage, motor noise, battery swelling and charge level, gimbal security, firmware and calibration
- Operations: take-off and landing points, return-to-home altitude setting, behaviour on loss of link, sunset time
Without records there is nothing to manage
Flight logs and maintenance history protect the business when something goes wrong, and they are also the evidence of flight experience needed to sit an operator certificate examination. At minimum, keep the following.
- Date, time and place of flight, operator, aircraft and batteries used
- Purpose of the flight and the approval number
- Flight time and anything unusual
- Parts replacement and inspection history, and battery charge cycles
Batteries in particular need managing. Number them individually to track cycles, and set a rule for retiring any pack that shows swelling or a sharp voltage drop, with no second thoughts.
Emergencies and division of roles
Real incident response happens while everyone is rattled, which is why the response to each situation has to be decided in advance. Loss of link, unstable GPS, motor trouble, an unexpected person entering the area, an aircraft coming down — set out what to do in each case on a single sheet and take it to the site.
On any site of scale, you should also separate the roles of operator and observer. When the operator is watching the screen and the surroundings at once, an approaching person or an obstacle is easy to miss. Simply assigning someone else to set the cordon and handle bystanders cuts the risk substantially. Reporting procedures, the contact chain and the threshold for notifying the client after an incident should be fixed in advance too.
The moments when the system breaks down on site
- An urgent request for extra footage, and straying just outside the approved area
- The sun starting to go down and "just one more shot" carrying you into night flying territory
- Putting a newly acquired aircraft to work without adding it to the insurance policy
- The operator being swapped out for someone without the certificate for that aircraft's weight band
- A checklist existing but with nobody designated to sign it, so it becomes a formality
Most of these begin not with deliberate breach but with schedule pressure. That is why a system only works if it goes beyond "don't do that" to include stop criteria — "under these conditions, the shoot moves to another day". Related laws and standards can be revised, so check the current position on the Drone One-Stop Civil Service or in Ministry of Land, Infrastructure and Transport notices.
Light Beyond Drones runs drone training and commercial filming together in Daejeon, so we treat this system as a working field standard rather than a chapter in a textbook. If you are preparing for commercial operations, we can advise on the stage after certification too: building the checklist, managing flight and maintenance records, and matching qualifications to people. Tell us how many aircraft you operate and what kind of sites you work, and we will set out how to start a checklist and record format at that scale. You are welcome to send that along with a training or filming enquiry.
