For those who are unaware of the imminent changes relating to the flying of SUA (Small Unmanned Aircraft) in the UK, here is a link to the ANO Cap 1763 which will come into force on 13th March. http://publicapps.caa.co.uk/modalapplication.aspx?appid=11&mode=detail&id=9002
In addition, it's worth emphasising, those who operate a SUA for commercial purposes, without the correct CAA permissions, will be doing so illegally. If you are unsure whether the correct training and permissions are required, it is defined as:- “commercial operation” means any flight by a small unmanned aircraft that is performed under a contract between the SUA operator and a customer, where the latter has no control over the operator, in return for remuneration or other valuable consideration. For example, this could include free advertising or some kind of barter arrangement, or even if the operator would benefit from monetising their work on YouTube. So it isn't just about receiving financial recompense.
I suggest this document is read by anyone involved in the procurement of SUA equipment or hiring of operators, as it will be a useful insight into the legalities of flying drones in the UK.
