Do WixEd Wings UAS Flights Over Power lines?What Kind of Data Needs to Be Taken During Inspections?Waiting For A Few More Steps … in The RegulationsSo far the most widely used inspection method is the one performed by manned helicopters and in specific areas with inspection by ATVs or on foot. But expensive helicopter operation is noisy and ecologically unsustainable. This is where we ask ourselves if the UAS sector, especially those with wixed wings, can be an alternative and provide new technological solutions that will complement or even replace the use of manned helicopters later.
