Drone Rules for Mairiporã
Drones are permitted across the municipality of Mairiporã but face strict constraints due to complex environmental protections and civil aviation codes. Under standard DECEA rules, professional mapping flights require an approved request through the SARPAS portal and must maintain a maximum altitude limit of 120 meters
Geographically, Mairiporã is a mountainous municipality located within the elevated Serra da Cantareira region, just north of the Greater São Paulo metropolitan area. The physical terrain is defined by dramatic topographical elevations, deep valleys, dense Atlantic Forest vegetation, and the expansive Paiva Castro reservoir. This sharp mountain relief creates severe microclimatic and aerodynamic flight hazards, including sudden, low-hanging ridge fog, intense thermal updrafts along the slopes, and localized wind tunnels that can quickly destabilize lightweight multirotor setups. The urban and semi-rural layout presents widespread structural challenges, featuring a web of high-voltage power transmission grids, cell towers, and steep residential developments nestled into the hillsides that cause intense radio frequency interference (RFI). Additionally, the massive elevation drops and vast stretches of deep, protected forest canopy ensure that any mechanical emergency or telemetry loss will result in an unrecoverable crash in highly inaccessible terrain.
