There was a comment somewhere deep in the thread about the new rules which asked if there was a simple graphic which summarised the new regulations. It didn’t seem that one existed, so I took the initiative to make one.
It’s not intended to be entirely comprehensive as there was a balance to be struck between over-complicating things while still getting as much information included as possible. The new Where can I fly my drone in the UK? - Good 2 Go - Can I fly my drone here? is a great place to validate your plans in more detail than I was able to present in this document.
Remember this only covers the regulations in relation to flight, you still need to ensure you don’t endanger people or property and consider any privacy issues.
