1. Pre-Flight Planning

Airspace Authorization: Verify the operational airspace using FAA-approved applications (e.g., B4UFLY, Airmap). Ensure the location is not in restricted or controlled airspace (Class B, C, D, or E). If controlled airspace access is needed, obtain necessary LAANC (Low Altitude Authorization and Notification Capability) approval.

Weather Check: Confirm weather conditions are safe for flight using reliable weather sources. Ensure wind speeds and visibility are within FAA Part 107 regulations.

Equipment Check: Conduct a thorough inspection of the drone and all associated equipment (batteries, camera, propellers). Ensure the drone is registered with the FAA and has an up-to-date registration number.

Flight Plan Review: Outline a flight plan that covers the specific areas of the site or roof that need to be documented, accounting for any potential hazards (e.g., power lines, trees).

2. On-Site Preparation

Site Survey: Perform an on-foot survey of the site and building to identify obstacles and potential hazards. Take note of emergency landing zones.

Stakeholder Notification: Inform relevant site stakeholders (e.g., property managers) of the planned drone operations, ensuring that no unauthorized persons are in the flight area.

Check for Bystanders: Confirm the site is clear of non-essential personnel. Set up safety cones or signs if needed.

Safety Equipment: Bring safety gear such as high-visibility vests and set up barriers if necessary.

3. Flight Operations

Pre-Flight Checklist: Double-check the drone’s GPS, compass calibration, and battery levels. Ensure the camera settings are configured for the best documentation quality.

Takeoff Protocol: Follow standard takeoff procedures and hover at a low altitude momentarily to check stability and control responsiveness.

Maintain Line of Sight (LOS): Always keep the drone within visual line of sight as per FAA Part 107 regulations.

Altitude Compliance: Do not exceed the maximum allowed altitude of 400 feet above ground level (AGL) unless operating within 400 feet of a structure and without exceeding its height.

Avoid Flight Over People: Ensure the drone does not fly over uninvolved individuals.

4. Roof and Site Documentation

Structured Approach: Start with broad, sweeping passes of the roof and site for context. Use specific passes for detailed sections or problem areas.

Capture Angles: Photograph and film at various angles to ensure comprehensive coverage of key features such as HVAC units, gutters, or structural anomalies.

Monitor Battery Levels: Keep an eye on battery levels to allow for a safe return and landing.

5. Post-Flight Protocol

Data Review: Immediately review footage and images to confirm the quality and completeness of documentation.

Equipment Check: Inspect the drone and equipment for any damage or wear.

Flight Log Update: Record flight details including date, time, location, and any incidents or observations.

6. Reporting and Compliance

Report Incidents: If an incident occurred during the flight, report it to the FAA as required under Part 107.

Compliance Records: Maintain records of airspace authorizations, flight logs, and equipment maintenance for auditing purposes. By following these procedures, FAA Part 107 pilots can ensure safe, compliant, and efficient drone operations for retail site and roof documentation.
