The regulatory revisions for drone surveying changed “whether you can fly” to “how you operate”

Many practitioners interested in drone surveying, when they hear about regulatory revisions, first worry about whether permits are now required, whether flying has become more difficult, or whether paperwork has increased. Those concerns are important, of course. However, what has actually changed more significantly on the ground is not just the simple question of flight permissibility. The overall design of operations—what aircraft to use, who operates them, under what conditions, and what records to keep—has changed.

Previously, many sites treated drones as a convenient imaging tool within surveying work and focused operations on day-of-flight preparations and safety checks. After the regulatory revisions, however, the entire operation including aircraft management, pilot requirements, assessing flight categories, organizing flight plans, keeping logs, and verifying the accuracy and deliverables of surveying results is now under scrutiny. In other words, drone surveying has shifted from being an equipment-usage task to being an operation run reproducibly in accordance with regulations.

This change does not just mean extra hassle on site. Rather, because the necessary management items have become clearer, it is now easier to see what to prepare to balance safety and quality. It is becoming easier to create systems that sustain a consistent standard regardless of who is in charge, instead of relying solely on individual intuition or experience. This is particularly significant for companies handling multiple simultaneous projects or organizations where imaging and surveying roles are separate: the regulatory revisions are an impetus to formalize internal rules.

This article does not provide a detailed legal commentary on the revisions; instead, it organizes what has changed in drone surveying fieldwork from five practical perspectives. It is intended to make the practical check points visible for those planning to introduce drones as well as those who already operate them but want to review procedures.

Mandatory registration for aircraft weighing 100 g or more changed how sites prepare

The first point to grasp about the regulatory revisions is that unmanned aircraft weighing 100 g or more must now be registered. As a result, preparing for drone surveying is no longer just about charging batteries, checking whether a flight permit is needed, and bringing the aircraft to the site. You now need to ensure that the aircraft are properly registered and managed before they leave for the field.

What matters here is less the act of registration itself than the management system premised on registration. For example, the same aircraft may be reused across multiple projects on site. If it is unclear who manages which aircraft, whether registration information matches the physical aircraft, or whether aircraft identification is correct, confusion can arise during pre-flight checks. This is especially true when a company has multiple aircraft or operates backup units: understanding registration status becomes not a clerical task but part of site quality control.

In drone surveying, not only the airframe but also the mounted camera and peripheral equipment, flight conditions, and imaging settings all affect deliverables. Therefore, being able to trace which registered aircraft was used for which project leads to improved traceability. If questions arise about the quality of captured data, being able to track not only the pilot on the day but also which aircraft was used under what conditions has significant practical value.

Moreover, the mandatory registration requirement makes it easier to codify a basic internal rule such as “only registered aircraft are operationally permitted.” Small aircraft that had previously been used on an ad-hoc basis now need to be evaluated for whether they fall under management based on weight class. In short, after the regulatory revisions, simply owning an aircraft is no longer synonymous with having it ready for operational use.

This point is important even for projects involving subcontractors or partner companies. Thinking “the subcontractor will fly it, so it’s not our concern” or “only filming is outsourced, so no checks are necessary” is insufficient. Even as a recipient of deliverables, you are weakened later if you cannot explain under what aircraft management regime the flights were conducted. Practically, it is realistic to include confirmation of aircraft registration in contracts and work meetings and to embed it in pre-flight checklists.

In short, the change brought by mandatory registration for aircraft weighing 100 g or more is not merely an increase in registration tasks. It has made it routine at the pre-departure stage to treat aircraft as managed assets, assign appropriate aircraft to projects, and keep traceable records. If you intend to conduct drone surveying continuously, this change is a foundational point to grasp first.

Risk-based category classifications changed how flight plans are devised

Another major change is the clarification of category classifications based on flight risk and the approach to permit and approval for specified flights. In practical fieldwork, this change is more accurately characterized as “you need to redesign the flight plan from the start” rather than “you need to do more work to check where you can fly.”

Drone surveying risk varies greatly depending on the terrain or structures being surveyed, the surrounding environment, flight altitude, flight path, and takeoff/landing locations. After the regulatory revisions, you must pre-assess how risky a flight at a given site is and organize necessary measures according to that category. In other words, surveying planning and flight planning should not be treated as separate; they increasingly need to be designed together.

For example, deciding a flight route solely to capture a wide area can complicate procedures and safety management due to interactions with the surrounding environment. Conversely, by considering flight categories and optimizing takeoff/landing points or flight direction, you may achieve the same deliverables while reducing necessary procedures and site burden. What is required here is not just piloting skill but the ability to design the flight method while considering the project as a whole.

As a result of this change, pre-study responsibilities have increased for surveying personnel as well. Previously, some operations worked by doing a field check and making fine adjustments on the day; after the revisions, you need to determine before entering the site which categories the planned flights might fall into and how to approach permit approvals. Setting the survey area, image overlap rates, number of flights, placement of assistants, and access control should be considered not merely as efficiency issues but as part of risk reduction.

It is important to note that organizing category classifications is not meant to discourage fieldwork. Rather, it is a framework to clarify what to pay attention to in each project. The aim is not to avoid high-risk conditions at all costs but to incorporate necessary countermeasures in advance. In practice, if this mindset is not shared on site, surveying staff may prioritize imaging quality while flight staff err on the side of safety, and the plan ends up mismatched.

Therefore, after the regulatory revisions, flight plan creation should not be left solely to a specific individual; at minimum, the site manager, pilot, and the person responsible for verifying surveying deliverables should share the plan’s premises. Clarifying what accuracy is required where, what conditions are indispensable, and what areas might allow alternatives makes it easier to produce realistic plans aligned with the category classifications.

The essence of the regulatory revisions is that operations have shifted from confirming the need for permits after the fact to designing flight plans based on risk categories up front. The success of drone surveying increasingly depends not only on day-of-flight piloting but on the quality of pre-flight planning.

Reporting of flight plans and flight logs changed where the operational burden lies

Among the regulatory revisions, one change that field staff are likely to feel in daily practice is the clarification of operational record-keeping and procedural burdens such as reporting flight plans and keeping flight logs. This is not simply an increase in paperwork; it is a change that requires deciding where to check, where to record, and who is responsible, otherwise operations will not function.

Typical drone surveying workflow includes pre-flight preparation, on-site safety checks, post-flight data organization, and deliverable creation. After the regulatory revisions, it is necessary to naturally integrate reporting and recording elements into each stage of that flow. Flight plan reporting relates to pre-flight arrangements, while flight logs are involved in post-flight review and ongoing management. Although both could be consolidated later if one tried, in reality deferring them increases the likelihood of omissions.

In surveying work, attention often shifts immediately after flight to checking captured data and handing it off to the next process. As a result, record-keeping tends to rely on the operator’s memory. But after the revisions, record-keeping itself is an official part of operations. Being able to trace when, where, who used which aircraft and what kind of flight was conducted helps not only safety management but also later verification and recurrence prevention. When questions arise about surveying results, confirming flight conditions helps isolate causes.

This change makes it important to design mechanisms that do not overburden the field with record-keeping. For example, simply separating items to check before flight, items to record during flight, and items to整理 after flight reduces confusion for the responsible person. It is also effective to distinguish items that can only be confirmed on site from those that can be complemented at the office. Trying to complete everything on site can undermine concentration on surveying tasks, while pushing everything to post-processing can reduce record accuracy.

Standardizing checklists for field use, pre-operation preparation sheets, and post-flight record formats is also effective in reducing reliance on individual ways of working. Experienced staff can organize everything in their heads, but new staff or temporary reinforcements may not be able to reproduce the same process. Standardization of these tools makes regulatory compliance and training progress easier. This is not about onerous document management but about providing tools so people do not get lost on site.

Additionally, clarifying operational records has made it easier to review internal role allocation. Even in sites that previously assumed pilots handled everything, dividing responsibilities among plan creation, execution, record confirmation, and result organization can be more stable. As the number of projects increases, it becomes unrealistic to expect pilots to manage procedures, operations, and quality checks all at once. The regulatory revisions provide an opportunity to reconsider such overloads.

In short, what has changed with clearer flight plan reporting and flight logs is not whether administrative tasks exist, but that operations and record-keeping must be designed together rather than treated separately. Records should not be kept just because they are mandatory but used as foundational information for safety and quality management—this perspective is indispensable for future drone surveying.

The pilot competency certification system changed how personnel are selected

Another major point of the regulatory revisions is the establishment of a pilot competency certification system for unmanned aircraft. This has changed how we think about personnel who fly aircraft on site. Previously, extensive flight experience was sometimes considered sufficient, but after regulatory establishment, you need to plan more deliberately who will be assigned to fly.

What is important here is not to judge a person solely by whether they hold a competency certificate. In practice, what matters most is placing personnel who can safely carry out the flight required for the project and achieve the desired surveying deliverables. With the certification system clarified, organizations can more easily codify which level of projects can be entrusted to whom.

In drone surveying, it is crucial that pilots not only have good stick-and-rudder skills but also understand the surveying objectives. For example, they must ensure complete coverage of the target area, secure necessary overlaps, minimize unnecessary flight repetitions, and adjust plans according to weather and surrounding conditions. Establishing the system increases the need to develop and evaluate operational capabilities that include such judgment, not only by experience.

This change also affects how training is conducted. Previously, operations could function with on-the-job learning for skilled personnel, but after the revisions it is better to establish a training system that covers foundational knowledge, understanding of flight categories, safety management, record creation, and emergency response. In organizations where surveying and operations divisions are separate, it is advisable to share the basics of the system not only with pilots but also with site managers and those who verify deliverables. If only pilots understand the system and planning and decision-making do not permeate the site, operations remain unstable.

Furthermore, having the pilot competency certification system clarifies how to explain staffing to clients and stakeholders. It becomes easier to demonstrate internally and externally who is assigned to flight and under what premises. This is particularly important for projects with high public interest; clarifying how staffing requirements are considered increases overall project credibility.

At the same time, assuming the system alone is sufficient is dangerous. In practice, many capabilities cannot be measured on paper: field experience, understanding of target objects, a feel for surveying deliverables, and team coordination skills. Therefore, in the post-revision field, it is important to use certification as a baseline while making placement decisions tailored to actual projects. For example, standard projects and those with complex surrounding conditions requiring frequent plan changes demand different levels of capability. Having the ability to allocate personnel based on that difference will ultimately support both safety and quality.

In short, the pilot competency certification system shifted operations from ad-hoc assignment of pilots to selecting personnel based on project risk and deliverable requirements. If drone surveying is to be established as a continuous operation, organizing personnel assignment thinking is as important as aircraft management.

In public surveying, operations based on work procedures and accuracy control became more important

For sites involved in public surveying, the regulatory revisions have heightened the importance of conducting unmanned aircraft operations, deliverable verification, and accuracy control according to work procedures and manuals. This is not just about following prescribed steps; it is because surveying results must be explainable and reproducible.

Drone surveying can acquire wide areas in a short time, but the quality of results can vary depending on flight and imaging conditions, how control points are handled, and processing procedures. Therefore, in contexts like public surveying where objectivity is strongly required, simply proving that the aircraft was flown is insufficient. It is important to document the procedures used, how accuracy was managed, and what confirmations were performed before compiling deliverables.

After the regulatory revisions, this idea carries more weight. Because flight rules and categorization have been clarified, there is now greater scrutiny on whether, after flying appropriately, appropriate surveying results were produced. In other words, flight legality and the validity of deliverables should be confirmed separately; one alone is not enough.

It is important not to misunderstand this change. Having permits or procedures in order does not automatically mean the surveying is adequate, nor does having a high-performance aircraft guarantee quality. In public surveying, you need to incorporate from the start how to secure deliverable standards and accuracy according to work procedures and manuals. For example, decide flight conditions at the planning stage according to required accuracy levels, organize on-site verification items, and manage the entire process from post-acquisition data checks to deliverable validation.

In this context, the regulatory revisions clarified prerequisites for quality management rather than simply adding constraints. Because flight conditions, pilot requirements, and record-keeping are organized, you can more easily build surveying quality control on top of them. Conversely, if those prerequisites are ambiguous, deliverable verification and explanation become weak.

Also, in public surveying, if internal work standards vary by project, ensuring quality becomes difficult. If the depth of pre-flight checks differs among staff, post-capture data checks vary, and criteria for deliverable verification differ, stable results are hard to achieve despite regulatory compliance. Therefore, using the revisions as an opportunity to align internal procedures and manuals is important. Practically, start by preparing procedure sheets and checklists that are actually used on site rather than creating a massive system.

From the public surveying perspective, there are naturally situations where drone capture alone is insufficient. It is important to determine which parts are effectively captured from the air and which require ground checks or supplementary measurements, and combine them appropriately. After the revisions, attention tends to focus on flight rules, but the ultimate goal remains obtaining surveying deliverables at the required quality. Therefore, the important question is not whether to use unmanned aircraft, but how to position drone-based processes within the overall workflow.

The essence for public surveying after the regulatory revisions is that we have moved from an era where drones could be used to an era of using them appropriately within the framework of procedures and quality control. If you want to increase the stability of field deliverables, you need to consider understanding flight regulation and standardizing surveying procedures together.

Operational flows sites should review after the regulatory revisions

Considering the five changes described so far, what sites really need to do after the regulatory revisions is not to tack on individual measures as they arise but to review the entire operational flow. In drone surveying operations, aircraft registration, flight planning, record creation, pilot assignment, and accuracy control tend to be handled by separate people, but after the revisions these elements must be linked or problems will arise.

The first thing to review is initial checks when projects are accepted. In addition to the target area, surrounding environment, required deliverables, and deadlines, it is important to quickly assess how much flight risk the project entails and what management will be required. If this assessment is delayed, a surveying plan may be finalized first only to discover later that flight conditions are incompatible, causing rework. After the revisions, it is safer to have at least one early information-sharing session among sales, the site manager, assigned pilot, and the person verifying deliverables.

Next is the assignment of aircraft and personnel. Choosing an appropriately registered aircraft, assigning a pilot who matches the project conditions, and placing assistants or verifiers as needed are fundamentals. Deciding these assignments the day before a project makes both regulatory and quality compliance unstable. While schedules may change, basic allocation policies should be established in advance.

You also need to review when records are made. Even if you recognize that flight plan reporting and flight logs must be done, if it is unclear when, who, and in what format they will be processed, omissions happen on site. After the revisions, do not treat records as after-the-fact administrative tasks; structure the flow to naturally occur before, during, and after the flight. This flow helps maintain operations even when new personnel join.

Additionally, move beyond the mindset that “if it was captured, it’s fine” when confirming deliverable quality. Check for missing coverage, whether required quality was achieved, and for public surveying, whether confirmations aligned with work procedures and manuals were performed. Dividing checks into initial on-site confirmation and secondary office verification makes operations easier. After the revisions, it is increasingly important to separately manage that a flight was conducted and that the results are usable.

For internal training, do not treat the regulatory revisions as a one-time notice. Management of aircraft registration, the concept of risk categories, how to keep records, how to view competency requirements, and quality control for public surveying are practices that only become established through repeated use on site. Short briefings or post-project reviews tied to actual projects help institutionalize regulatory responses as on-the-job knowledge.

What matters in reviewing operational flows after the revisions is not to create a perfect system from the outset. Rather, adapt to your company’s project scale and structure by deciding the minimum essential checkpoints and ensuring they are reliably performed. While attention often focuses on developing hardware, what creates differences in practice is operational stability. If you view the regulatory revisions positively as clarifying the standards needed to build that stability, directions for improvement become clearer.

Summary

In one sentence, what changed with the regulatory revisions for drone surveying is that not only the permissibility of flights but also the management standards of field operations have been raised. Mandatory registration for aircraft weighing 100 g or more means aircraft must be treated as managed assets rather than merely owned. Clarifying risk-based category classifications increased the weight of pre-designed flight planning rather than on-the-spot decisions. Clarifying flight plan reporting and flight logs made records foundational information for safety and quality rather than afterthought administration. Establishing a pilot competency certification system made the process of deciding who flies more organizational. And in public surveying, the importance of managing deliverables and accuracy according to procedures and manuals became clearer than ever.

As a practitioner, it is important not to view the regulatory revisions only as bothersome additional tasks. Now that necessary checkpoints are organized, it is easier to design the full flow from pre-project preparation, on-site operation, post-flight records, to deliverable quality confirmation as one integrated process. Moving away from personalized operations and creating systems that achieve consistent standards regardless of who is responsible will be a major differentiator in future drone surveying.

Also note that many field situations are not completed by aerial capture alone. Depending on surrounding conditions and required accuracy, combining ground-based position checks, supplementary surveys, and deliverable confirmation often improves overall efficiency and quality. Tools that make on-the-ground positioning reliable are useful in such cases. For example, using LRTK-type iPhone-mounted GNSS high-precision positioning devices makes it easier to secure positional verification and field supplementation needed before and after drone surveying. After the regulatory revisions, it is more important to design operations that connect aerial and ground work rather than isolating flight alone. If you want to improve reproducibility and explainability of site operations, review your practices from that perspective.
