Study Notes
Preparation for Aerial Mapping and Inspection
- Survey the area for obstacles such as busy roads or power lines before the flight.
- Maintain visual line of sight of the drone and avoid flying over people or moving vehicles.
- Recommended altitude for three-story buildings is 150 ft AGL; for buildings over five stories, consider flying at 200 ft AGL.
Safety and Compliance
- Establish a designated takeoff and landing area to prevent public interference; use safety cones and tape.
- Prepare for FAA inquiries regarding safety briefings and operational plans.
Mapping and Modeling
- 2D maps, orthomosaics, and 3D models created may not be geo-referenced; ensure understanding of limitations.
- Arrow points and ground control points (GCPs) can be used to enhance positioning accuracy for contractors.
Pre-flight Setup
- Set up the drone and mission parameters before powering on the drone to conserve battery life.
- Begin with ensuring the drone is functional: check battery, attach propellers, and prepare the remote.
Minimum Obstacle Clearance Altitude (MOCA)
- MOCA is the minimum height above the tallest obstacle within the planned flight area.
- Identify the tallest obstacle and record its height, ensuring to fly at least 10 ft (3 m) above this height to avoid collisions.
Flight Preparation Steps
- Set the drone’s return-to-home altitude above the established MOCA for safety.
- Configure mission settings: enable continuous file index mode and adjust obstacle avoidance features as needed.
- Conduct a compass calibration using the DJI Go app before flying.
Launching the Mission
- Check all automated settings before starting the mission.
- Establish organized routines to facilitate smooth operations during flights, promoting efficiency and safety.
Preparation for Aerial Mapping and Inspection
- Conduct a survey to identify obstacles like busy roads and power lines prior to drone flight.
- Maintain visual line of sight for effective control and avoid flying over populated areas or moving vehicles.
- Recommended flight altitude is 150 ft AGL for three-story buildings; increase to 200 ft AGL for buildings over five stories.
Safety and Compliance
- Designate a clear takeoff and landing area using safety cones and tape to minimize public interference.
- Be prepared to provide safety briefings and operational plans to FAA representatives to ensure compliance.
Mapping and Modeling
- Understand that 2D maps, orthomosaics, and 3D models may lack geo-referencing and know their limitations.
- Utilize arrow points and ground control points (GCPs) for enhanced accuracy in positioning for mapping projects.
Pre-flight Setup
- Configure the drone and mission parameters prior to powering on to help conserve battery life.
- Perform a functionality check: ensure battery is charged, attach propellers, and prepare the remote control.
Minimum Obstacle Clearance Altitude (MOCA)
- MOCA refers to the minimum height necessary above the tallest obstacle in the planned flight area.
- Identify the tallest obstacle’s height and plan to fly at least 10 ft (3 m) higher to prevent collisions.
Flight Preparation Steps
- Set the drone’s return-to-home altitude above MOCA for added safety during operations.
- Adjust mission settings such as enabling continuous file indexing and provide necessary obstacle avoidance configurations.
- Perform a compass calibration using the DJI Go app to ensure accurate navigation before takeoff.
Launching the Mission
- Review all automated settings thoroughly to avoid errors before initiating the mission.
- Develop structured routines to enhance operational efficiency and safety during drone flights.
