What is the required distance for an RPA to maintain from a heliport under Advanced Operations?

The requirement for an RPA (Remotely Piloted Aircraft) to maintain a distance from a heliport under Advanced Operations is set at one nautical mile. This distance is established to ensure safety and to prevent potential conflicts between the RPA and manned helicopters operating in the vicinity of the heliport. Maintaining this buffer zone allows for safe operations and the ability for both types of aircraft to operate without interfering with each other, particularly in high-traffic areas where helicopters frequently take off and land. The one-nautical-mile separation helps to minimize the risk of accidents and enhances overall situational awareness for pilots operating in those areas.

The other distances mentioned (two, three, and four nautical miles) could be seen as overly cautious and unnecessary for typical operations under the Advanced Operations framework, where the one-nautical-mile separation has been determined to be adequate for safety and operational effectiveness.
