4. Maintain line of sight
Once you’ve gone through your checklist and ensured that your drone is fit for flight, do take note of the height limits for recreational drone activity. According to the Civil Aviation Authority of Singapore’s (CAAS) guidelines, drones should fly below 200 feet (which is about 60 metres, or 12 storeys of an HDB apartment block), beyond which an activity permit is required for each flight session or block of repeated flight sessions.

Also, the rule of thumb for drone flights is to never let the drone out of sight. If you can see your drone, you’ll be able to adjust its flight path to avoid obstacles, or bring it ‘home’ when its batteries are nearly exhausted.

From ground at Marsing park likely cannot see it by causeway checkpoint.
