+ Geographically, the Caatinga-Cerrado transition valley of Peruaçu is a massive, dry canyon carved by the Peruaçu River in the north of Minas Gerais, famous for its colossal limestone caverns, thousands-of-years-old rock art panels, and steep, dramatic cliffs like the Janela do Mansinho. The physical topography is a combination of sheer vertical stone walls, narrow karst ravines, hidden sinkholes, and fragile dry forest canopy. This landscape generates extreme microclimatic flight hazards, including severe thermal drafts rolling off the sun-baked limestone and sudden wind vectors inside the canyon mouths. Operating a drone here introduces immense technical risks: the deep, enclosed stone gorges trigger intense satellite signal shading and multipath GPS errors. This environment poses a critical risk of telemetry loss where any automated return sequence will cause the aircraft to collide directly with the canyon walls or drop into inaccessible, unrecoverable deep limestone crevices.
