The idea that drones get used at earthquakes, wildfires, floods and major accidents is familiar. The actual role, though, is far more prosaic than the dramatic rescue footage suggests. Specific figures from individual incidents, the operating status of particular agencies and the scale of any deployment differ by country and need separate verification, so what follows concentrates on the use patterns that recur consistently across overseas practice.
The biggest contribution is situational awareness
The central problem in the early hours of a disaster is usually not that resources are scarce. It is that nobody knows where to send them. Drones are used to close that gap.
- Damage extent: rapidly imaging the condition of roads, bridges and buildings in areas that have been cut off
- Thermal search: an aid to identifying people or heat sources at night or through smoke
- Mapping: converting captured imagery into orthophotos or three-dimensional models so damage can be quantified rather than estimated
- Pre-entry risk assessment: checking the state of a structure at risk of collapse before crews go inside
- Communications relay: trials using aircraft as temporary relays where ground networks have been damaged
What makes these operations difficult
A disaster site differs sharply from routine flying. These are the constraints that overseas operating guidance emphasises consistently.
- Manned aircraft such as helicopters are operating in the same volume, so airspace coordination comes first. An uncoordinated flight obstructs the rescue effort rather than assisting it
- Separate procedures are needed for operating when the communications network is degraded
- Crews must know the airframe's limits in high wind, rain, smoke and darkness before they are tested by them
- Standards are required for handling captured imagery and protecting the privacy of people in it
- Without relief crews, sustained response is impossible. Pilot fatigue management is an operational item, not an afterthought
It also bears repeating that flying a drone into a disaster area without authorisation can ground firefighting and rescue aircraft entirely. Individual pilots should follow the designated control arrangements without exception.
Turning imagery into decisions
The failure mode that recurs in disaster response is rarely technical. It is a failure of information transfer — good footage is captured and the command post cannot use it. Preventing that means settling several things before the aircraft launches.
- Define who is viewing this and what decision it supports before anything is filmed
- Agree the deliverable format in advance: a live video feed to watch, or an orthophoto processed so areas can be measured
- Standardise the coordinate system and file naming so multiple agencies can overlay the same material
- Secure baseline data during normal operations so before-and-after comparison is possible at all
How Korea differs
The point Korean response organisations most need to internalise is the lead time on approvals. Night flight and beyond-visual-line-of-sight flight both require special flight approval, applied for to the Regional Aviation Administration, with a stated processing period of 30 days, extendable to 90 days in special circumstances, and subject to a conformity review against the national safety standard for special unmanned aircraft flight. In other words, applying after a disaster has occurred is already too late. Having the approval framework and procedures in place during normal operations is itself the response capability.
Beyond that, flight above 150m above ground level, in controlled airspace or in prohibited airspace requires flight approval, and aerial photography permission is a separate process administered by the Ministry of National Defense rather than by the aviation authority. Device registration applies to all commercial aircraft regardless of weight, and to non-commercial aircraft above 2kg maximum take-off weight, filed through the Drone One-Stop Civil Service under the Ministry of Land, Infrastructure and Transport. Foreign responders and international agencies planning to operate in Korea should note that these are four distinct filings with four distinct owners.
Pilot certification is based on aircraft weight, which has direct consequences for disaster work: an airframe carrying a thermal camera and large batteries becomes heavy quickly and pushes the crew into a higher class. Above 7kg up to 25kg is Class 2 at 10 hours of logged flight experience, and above 25kg up to 150kg empty weight is Class 1 at 20 hours. Above 2kg up to 7kg is Class 3 at 6 hours, and above 250g up to 2kg is Class 4 via an online course. Certification is administered by the Korea Transportation Safety Authority (TS). Where the US organises its rules around the pilot and commercial intent and Europe around operational risk, Korea organises around weight and airspace — but on the one axis that matters most in disaster work, BVLOS, all three converge on requiring individual review.
What Korean organisations need to prepare
Local governments, fire services and police organisations in Korea have been steadily adopting drones. What that adoption needs most is not airframes but people: the flying proficiency to operate in poor conditions, competence with thermal imaging payloads, and the skill to process captured material into something a commander can act on. Mandatory liability insurance for commercial and business use — a minimum of 150 million won bodily injury and 20 million won property damage — is another item any organisation-level operation must confirm.
Light Beyond Drones, based in Daejeon, offers remote pilot certification training alongside industrial field solutions in aerial imaging and surveying. If you are working towards public safety or disaster response, we would be glad to help you plan the order in which to build the certification class and equipment skills you will need.
