Where they fly
Each one has a different flight profile, a different payload and a different reason a person should not be doing it by hand. Below is what the work actually looks like from the air.
Scope
Everything on this page is agriculture, infrastructure, environment or public safety. We do not design, assemble or supply aircraft for defence, policing of individuals, weapons carriage or targeting. That is a fixed boundary, not a phase we are going through.
Within that boundary we are broad. The same engineering approach covers a spray rig over almonds and a thermal camera over a substation, because both problems start the same way: what has to be carried, how long, and how close to the ground.
If your job is not listed, describe it anyway. The honest answer is sometimes that a manned aircraft, a ground crew or an off-the-shelf machine is the better tool, and we would rather say that at the first conversation.
Agriculture
The oldest case for flying something small and slow. Terrain a tractor cannot cross, timing a contractor cannot match, and a crop that does not wait.
Infrastructure
Inspection is where the safety case is easiest to make. Every flight is a person who did not go up a tower, onto a roof, or out along a line.
Conductor, insulator and pole inspection along transmission and distribution runs, including thermal checks for hot joints.
Thermal sweeps across array fields to find dead strings, and close visual work on blade surfaces and nacelles.
Roofs, bridges, tanks, chimneys and communication masts, photographed close without scaffolding or a rope team.
Right-of-way patrol for encroachment, erosion and surface disturbance across long linear corridors.
Survey
Mapping is the application that changes a business process rather than just replacing a ladder. A site flown every fortnight produces a record of what actually happened, not what the schedule claimed.
Environment & safety
Four applications where the aircraft is not saving labour so much as buying time.
Thermal and optical sweep over terrain a ground team would take hours to cross, feeding a picture back to the people coordinating.
Early spotting over forest and scrub during high-risk periods, and overwatch of a perimeter once an incident is running.
Canopy condition, regeneration survey, wildlife counts and watercourse mapping across country with no road access.
Perimeter observation on industrial sites, plus indoor inventory flights through large warehouses and yards.
Honest limits
Every application above has a boundary. A supplier who does not mention them is selling, not engineering.

The area, the interval, the payload and the conditions. We will come back with a platform direction and the limits you should plan around.
