+ An airspace evaluation for Helipuerto del Hospital Universitario de Salamanca, located in the municipality and province of Salamanca (Castilla y León), emphasizes the definitive prohibitions enforced under Real Decreto 517/2024. UAS operations are entirely forbidden by default inside this infrastructure's active safety zone (servidumbres aeronáuticas), with the restriction taking effect directly from the surface level (0 meters AGL) upward to safeguard critical medical helicopter flight tracks. While remote pilots frequently rely on a 2.5km radius around the helipad as an acceptable reference value to map out local low-altitude hazards, any physical entry into this protected envelope requires lifting the default ban through a signed Operational Coordination Agreement with the facility operator. Furthermore, operators must check official charts to determine if their planned trajectories intersect with Controlled Airspace (CTR); if a CTR overlap exists, obtaining an explicit flight authorization from ENAIRE or the responsible air traffic control provider is a mandatory legal prerequisite alongside the infrastructure coordination.
