The practical answer
Choose a wind inspection package around the required surface detail, thermal question and review method. M4T and M400 with H30T are two equipment routes in this range; neither package alone supplies a complete blade assessment or a specialist automated inspection system.
Write the inspection question before choosing the platform
Start with the turbine owner’s actual need. A blade surface record, a nacelle exterior observation, a tower condition photograph and a targeted thermal enquiry have different viewpoints and acceptance criteria. Specify the component and intended decision before treating them as a single wind-farm survey.
Ask the responsible reviewer to identify the evidence they need and the areas that require another method. NLR’s AIRTuB review distinguishes external and internal blade inspection methods. [1] Build that distinction into the brief so an aerial surface record has a clear role alongside the owner’s wider maintenance programme.
A portable team route: M4T
WE-01 includes M4T, five flight batteries in total, Terra Flagship for one year, controller-battery charging accessories, training and support. WE-02 adds DJI Power 2000. Consider these when a portable thermal-capable kit matches the planned viewpoints and evidence requirements.
Test representative images with the reviewer before extending the task to a full turbine list. The important question is whether the required area can be identified and assessed from the approved capture position. A compact kit may simplify mobilisation, but a difficult viewpoint or unsuitable observation remains a planning issue.
A larger payload route: M400 with H30T
WE-03 provides M400 with H30T, five TB100 flight batteries in total, BS100 charging station, two WB37 controller batteries, Terra Flagship for one year and team training. WE-04 adds Power 2000. This wind configuration has five flight batteries, unlike the three in the industrial M400 kit.
Compare the larger system against the payload requirement, transport, charging and team arrangements. Include a handover exercise using representative turbine evidence. Aircraft size is only one part of the decision; the owner still needs an accepted method, a competent operator and a reviewer who can use the delivered files.
Use an acceptance image rather than a headline specification
Ask the reviewer to supply an example of useful evidence and explain what makes it useful. It might show an identifiable blade region, a surface feature with adequate context or a connection that needs closer examination. Agree how an unusable or obscured area will be marked.
Run the proposed capture and file workflow on a representative target. Check the original image at the intended review scale, not only the controller preview. A successful trial includes traceable file naming, location and an honest coverage statement. Keep the accepted example with the work instructions for subsequent visits.
Make the turbine owner part of the method
The owner’s operating and access instructions should shape mobilisation. Agree who coordinates the turbine status, releases the work area, communicates changes and authorises a restart after interruption. Ask the operator to document the flight method and conditions under which capture will be deferred.
Keep aviation, turbine-operation and engineering responsibilities explicit. The equipment purchase does not settle those responsibilities. A suitable team can explain how the task interfaces with the owner’s maintenance activity and where an additional specialist inspection belongs. This is more useful than buying around a generic promise of uninterrupted operation.
Specify three useful handover layers
First request a coverage record: turbine, component, date and areas observed or deferred. Next request indexed original photographs with sufficient overview context. Finally agree the specialist review output, including author, status and proposed follow-up. These layers can be linked without presenting every image as an engineering conclusion.
For recurring work, preserve the owner’s turbine and blade identifiers. Record repairs and component changes so later comparisons remain meaningful. Ask how observations will be transferred into the owner’s maintenance system and retained when a project account or contractor changes.
Choose software for the agreed output
Terra Flagship is included in these wind packages, but the handover may centre on individual component photographs rather than reconstruction. Ask the team to demonstrate the actual processing and indexing route using representative files. Confirm who supplies any specialist blade-analysis platform the owner requests.
A licence and an aircraft do not automatically include proprietary flight automation, damage classification or blade-expert review. Put those services on explicit quotation lines when needed. This keeps a useful general inspection kit distinct from a commissioned end-to-end specialist blade inspection service.
Questions buyers should resolve
Is thermal always the main blade inspection method? Let the blade specialist specify the method for the question. Does the Power version collect different evidence? It adds portable power to the same core configuration. Choose it after the charging and mobilisation plan is clear.
What should we send Irish Drone? Send the turbine type, target components, sample accepted evidence, site instructions and intended team. Use the blade surface guide for traceability, the thermal guide for thermal questions and the handover guide for recurring maintenance records.
An example of a useful buying comparison
A buyer with a defined tower and blade photography brief can ask each proposed equipment route to produce the same sample register. A separate thermal question should be assessed as its own deliverable. The reviewer can then say which evidence is accepted, which needs a changed method and what remains outside scope.
Use those answers to choose training, accessories and review support. Keep the comparison grounded in the owner’s requested output rather than the number of turbines or the nominal generating capacity of a site. The final quotation should name the chosen workflow and the responsibilities that accompany it.
