Hello all, I some questions about high interferance areas. There's a friend that needs a survey about a building in order to make a rehabilitation project. When checking the area, I've noticed that there was a building from our eletricity company. Once I went there with my P3pro to make the survey, I couldn't configure the compass as there was always the message of high interferance. My doubts about this are: 1- Can I balance the compass, get GPS coverage and "home point", in a relatively distant and safe place (where interferance is not a problem) and then fly up to this target area? 2- If I do so, is it safe to use the ATTI mode in this kind of works? Thank you all for the help, I've posted the map for you too see better this problem. Have great and safe flights!
