When photographing from a vantage point just east of Cocolalla, what is the maximum altitude (MSL) authorized to fly over a hill?

The maximum altitude authorized for flying over a hill is determined by the elevation of the hill itself, plus a safety margin. In this scenario, when photographing from a vantage point just east of Cocolalla, the chosen altitude of 5,360 feet MSL is appropriate. This altitude likely considers the height of the terrain as well as the necessary buffer to ensure safe operations above obstacles.

The rationale behind the chosen altitude aligns with aviation regulations that require UAS operators to maintain a minimum distance above obstacles while ensuring compliance with airspace altitudes. By flying at 5,360 feet MSL, the operator is effectively incorporating the height of the hill plus a buffer, enabling safe operations and adherence to regulatory guidelines.

An understanding of local terrain elevations and relevant FAA Part 107 regulations is critical to selecting an appropriate flying altitude, ensuring both the safety of the flight mission and compliance with regulatory requirements.
