LHW Partnership LLP has held a CAA Commercial Operations Approval Drone Licence since early 2015, and in 2016 was augmented with an additional Operational Safety Case approval zone of 20 metres to operate in restricted areas that permits the use of UAVs (drones) in areas that the normal 50m area of control will not permit without extensive prior notifications and additional resource.
This necessitated constructing an aircraft with dual redundancy on all critical aspects including power supply, GPS, flight controller, and ESC, motors / propellers emergency parachute to satisfy the CAA that the reduced area of control was acceptable. LHW Partnership LLP designed, specified, constructed and commissioned the UAV to meet the required standard.
Since 2014 LHW has recorded several hundred hours of flights, and undertaken numerous assignments for commercial and private clients across the UK.
LHW Partnership can undertake Visual Still & Video, and additionally Infra Red video and stills for scientific review.
The standard CAA approval allows the use of drones with control of a 50-metre area around the drone. Control means the people within the area are under the instruction of the pilot. In rural areas this control area is realistic, but for inspecting more urban areas, this will often mean that there are roads and other pathways that will need control. This is often impractical.
With a twenty-metre control area this equates to 16% of the area of control for a 50 metre approval.
This means most buildings can be inspected.
For buildings where a 20-metre approval is still not acceptable, then LHW has other solutions including extendable poles and hand-held photography.
