Guide to Drone Aerial Photography in the UK
We will use the term UAV throughout this informative article but you may find them online under different names and acronyms. This is because there is no standard term for this kind of equipment. The common names are:
UAV (unmanned aerial vehicle)
UAS (unmanned aerial system)
SUSA (small unmanned surveillance aircraft)
ROV (remotely operated vehicle)
RPA (remotely piloted aircraft)
Multirotor (tricopter, quadcopter, hexacopter, octocopter)
Quadcopter and Drone are the most popular terms used.
This list is not exhaustive. While there are fixed wing operators out there, the majority of these are not used for filming, therefore this guide will focus on multirotor and helicopter use as these are becoming most commonly used.
Why use a UAV or Drone?
Recent advances in camera, flight and battery technology mean that UAVs and Drones are now capable of obtaining footage at a quality comparable to that achieved by manned aircraft. Combined with the fact that UAVs can be used closer to the ground and nearer to people than manned aircraft, this means that they are becoming an incredibly versatile tool for filmmakers across a wide variety of genres. UAVs have been used to replace dolly and jib shots in awkward locations and can be used for dramatic lift and zoom shots.
The majority of UAV Drone operators will be significantly cheaper than hiring a helicopter. The ability to monitor the footage from the ground allows for directorial input to the flight team and immediate review of the footage. Control methods vary and include traditional transmitters, tablet and laptop control. The control method employed will be dictated by the type of filming required.
What about the legislation concerning UAVs and Drones in the Uk?
If a company or individual is operating their UAV or Drone commercially (which the Civil Aviation Authority defines as getting any kind of valuable consideration for your work) then their aircraft must be registered with the CAA and have a permit for aerial work. Any reputable company will be able to show you their permissions document for the aircraft they are going to use. This clearly shows the conditions they can fly under. The conditions vary slightly for different aircraft. If a company is operating without a permit for aerial work then it is possible that the pilot’s experience is questionable and it is unlikely that they are insured.
What qualifications do I look for?
Aside from checking the permit that allows aerial work, the CAA requires that pilots demonstrate a level of skill when they register their aircraft. Until recently it was possible to obtain a permission for aerial work with a British Model Flying Association Helicopter A certificate. New registrations are now generally required to complete a PFAW qualification, which is administered by various companies but we work closely with Aerial Motion Pictures who are a qualified entity for obtaining this qualification.
More information on our CAA Approved Drone training can be found here and current CAA Drone Training Courses we run.
This qualification consists of a theory exam and flight exam. The aim is to show that the pilot is knowledgeable about their own aircraft and how they can use it in UK airspace. The qualification is weight specific so if, for example, a pilot is qualified only to use a sub 7kg machine, they should not be flying a machine greater than 7kg for aerial work. All operators who have completed the course should be able to show you their certificate, which should tie in with the details on their permission for aerial work.
What are the limitations?
In order to make sure UAVs and manned aircraft are working in separate airspace, there are a number of limitations placed on UAV use. The rules below are subject to change by the CAA so it is worth noting that its best to check on there official website for upto date rules and regulations.
These are the main ones to keep in mind:
• The maximum altitude is 400 feet (120 metres)
• The maximum distance from the operator is 500 metres
• The minimum visibility needs to be 5 km
• UAV must be flown in line of sight of the operator
• UAVs cannot be flown at night without special permission
• Permission must be obtained from the owner of the take-off point
• UAVs cannot be flown within 50 metres of structures, vehicles or people that are not under the control of the person in charge of the aircraft. The rules are different for different weight classes unless a exemption is obtained.
This final point may sound very limiting but the key phrase here is “…under the control of…” It is perfectly acceptable to fly close to buildings and actors, for example, as long as permission has been obtained and the actors have been briefed about the use of the UAV. It would be highly irresponsible to fly over or near members of the public who are not aware of the purpose of the flight.
How to get insurance
There are specialist UAV insurance companies that are able to provide cover for UAV operations. As a bare minimum, the CAA recommends that the company or individual should have public liability insurance. Some insurance companies will not cover UAV use in high-risk areas though so do check this beforehand.
Most operators will have cover for their own equipment or cameras, but if you ask the company to use your cameras, their insurance will not normally cover your equipment. Flying hired cameras may be possible, but it is advised that the hire company is informed of this as their insurance may not cover UAV use.
It is also advised when starting out at hobby level flying Quadcopters and Multirotors to join the BMFA and get there third party liabibility insurance cover, more details can be found on the BMFA website.
Which size camera do I need?
The type of UAV and the size of a camera are closely linked. The size of the UAV will generally dictate the camera payload. The type of camera mount or gimbal the UAV uses is also very important.
Most individuals start off with a small quadcopter like a DJI Mavic that is capable of carrying a small compact camera or something like a GoPro. There are octocopters and hexacopters like the DJI S900 and S1000 that are capable of carrying cameras such as the Panasonic GH4, Canon 5D or Black Magic Pocket
Another very popular choice is the DJI Inspire 2 as these have built in HD Video Transmission and 4K Cameras as standard.
Generally, the bigger the camera, the shorter the flight time. With the larger cameras, flight times may be limited to 6-7 minutes per battery pack. However, in filmmaking, shot sequences are usually very short so this isn’t a major problem. Quadcopters.co.uk are the specialists in this field and can supply heavy lift platforms to bespoke requirements.
But with advancements in technology and lighter cameras becoming available flight times of over 20 mins are possible.
Camera gimbals used to be generally servo stabilised but new Brushless Type gimbals came into the market and were a game changer to this industry and already fantastic gimbals like the Zenmuse are making headway in this field but there are more and more to come soon. Some operators use a single pilot and camera operator setup, while others have a separate pilot and camera operator. This may affect costs as well as the quality of the final product. Costs of UAV hire, at present, tend to vary considerably but are generally proportionate to the video quality that the operator can achieve.
