Drones

What Are Drones? Types, Flying Principles and the DJI Neo 2 | Defines drones and UAVs (air, land, sea), covers lift/thrust/drag/weight with Bernoulli's principle and Newton's third law, introduces the DJI Neo 2 spec and does a first gesture-controlled palm takeoff; homework is to install the DJI Fly app and charge batteries to 80%.

Gesture Control Technologies and Drone Applications | Computer-vision features behind gesture flying (ActiveTrack subject tracking, palm takeoff/landing and return-to-palm, two-hand gestures), everyday drone uses, DJI Neo 2 specifications and the antenna, then setting up iPad control; task is to fly around a chair and photograph it from behind.

Drone Components, Gimbal and Remote-Controller Flying | Drone components and gimbal stabilisation, omnidirectional obstacle sensing and forward LiDAR, Mode 2 joystick layout and hover/roll/pitch/yaw, and flying with the remote controller; task is a school-wide photo hunt voted as "Best of Flying Day".

Remote Pilot Duties and Hong Kong Drone Law | Remote pilot and visual observer responsibilities, Civil Aviation Department categories A1/A2/B/C under the Small Unmanned Aircraft Order (Cap.448G), the flight log book and what to report if a drone is lost; challenge is a 2 m square circuit at 2 m altitude, clockwise then anticlockwise.

Standard vs Advanced Operation and the CAD Drone Map | Uses the CAD eSUA drone map, compares standard and advanced operations (approvals, night flight, restricted zones, HK$10m insurance), introduces the required flight-recording, airspace-awareness and real-time alert systems and how GNSS works; challenge is a timed search-and-rescue camera mission.

Equipment and Airspace Awareness for Advanced Operations | Detailed look at the equipment HKCAD requires for Category B and C drones (flight data recording kept 6 months, eSUA airspace awareness, audible/visual alerts) and GNSS constellations; closes with the search-and-rescue challenge.
