Permission for Commercial Operations

Our permission

We, being Altitude Surveys Ltd (the 'SUA Operator'), are permissioned by The Civil Avaiation Authority, in exercise of its powers under articles 94(5) and 95(2)(a) of the Air Navigation Order 2016 (‘the Order’), as amended, to operate small unmanned mulitrotor and helicopter type aircraft during the hours of daylight and night within UK airspace, for the purposes of commercial operations and for operations over or within 150 metres of any congested area, subject to the following conditions.

Any small unmanned aircraft operated under our permission shall not be flown:

  • Other than by persons employed by or contracted to Altitude Surveys Ltd;
  • Unless there is insurance cover that meets the requirements of EC Regulation No. 785/2004;
  • Unless the small unmanned aircraft is maintained within the direct, unaided Visual Line of Sight (VLOS) of the remote pilot, out to a maximum horizontal range of 500 metres;
  • At a height exceeding 400 feet above the surface, unless permitted to do so under article 94A(3) of the Order;
  • Within the flight restriction zone of a protected aerodrome, unless in receipt of the appropriate permission as required within article 94A of the Order;
  • Over or within 150 metres of an organised open-air assembly of more than 1,000 persons;
  • Within 50 metres of any person, vessel, vehicle or structure that is not under the control of the SUA operator or the remote pilot, except that during take-off and landing this distance may be reduced to 30 metres;
  • Unless it is equipped with a mechanism that will cause the small unmanned aircraft to land in the event of disruption to or a failure of any of its control systems, including the radio link, and the remote pilot has ensured that such mechanism is in working order before the aircraft commences its flight;
  • Unless the remote pilot is reasonably satisfied that any load carried by the small unmanned aircraft is properly secured, that the aircraft is in a safe condition for the specific flight, and that the flight can safely be made taking into account the wind and other significant weather conditions; and
  • Unless the flights are conducted in accordance with the current operations manual of the SUA operator, to include a site safety assessment, as well as records of each flight undertaken. The SUA operator must maintain records of each flight made pursuant to this permission, and must make such records available to the Civil Aviation Authority on request.

How can I verify this permission is genuine?

The CAA publishes and maintains a list of authorised commercial drone operators which is available free of charge to the public to download, under CAA publication CAP1361.

Every commercial drone operator who has been granted CAA permission will have a document from the CAA granting the permission and setting out conditions for its use. You should ask any operator that you are considering for commercial drone work to show you his or her permission document and discuss how the work might be achieved within the conditions of the permission. We will happily make our certification available when requested in the context of consideration for commercial drone work.
