Frequently Asked Questions

Where we can fly and where we cannot

It is probably easier to say where we cannot fly and below shows a graphical representation of the rules and restrictions as stipulated in our permission granted by the CAA.  Importantly we do need permission from the landowner to take-off and land the aircraft on their property before we are able to proceed.  At the time of take-off and for the duration of the flight we do need to maintain a 30 metre radius from the landing pad to people and property outside of the control of the pilot.

Where we can fly

After take off and for the duration of the flight a safe distance of 50 metres must be maintained between the drone and people, structures and vehicles, outside the control of the pilot.  In addition to the 50 metre rule the drone is not permitted to fly directly over people, structures and vehicles at any height.  The maximum height permitted is generally 120metres.

 

In the example above, if the requirement to photograph or film either the industrial buildings or the new housing estate, then the shaded areas show where the drone is not permitted to fly in accordance with the rules above.  In addition, the drone must be able to fly from the take-off area to the position where the photography is to commence without passing through any no fly zone.  Here we can see the flight from the take-off area to Fly Zone A to photograph or film either the industrial buildings or the housing is straightforward.  The job can proceed in Fly Zone A providing the drone does not encroach on any of the shaded areas.  Potential hazards the pilot and his crew will be aware of is the track running alongside the industrial units and the possibility of vehicles or walkers in this area.  Signage maybe provided and if it is a public footpath, spotters would be positioned there with radio contact with the pilot.  Safety is paramount at all times.

 

Achieving the same in Fly Zone B is not quite so simple where we would not be permitted to fly over any of the industrial units from the take-off position if we did not have permission from the owners of these units.  An alternative take-off position may be sought or it maybe possible to fly around Unit 1.

 

It is important all of these considerations are fully explored before the job commenced on site.  This is all part of a pre-site survey that needs to be undertaken.  The information is provided here to assist a potential client establish what is feasible and what is not. All of the above changes completely if permission is granted by the owners of all the properties affected.  We are then able to fly closer than 50 metres and also directly overhead.  The 120m maximum altitude requirement would still remain and we wouldn’t fly direct over people.  Safe operations still remains our paramount consideration.  [It should be noted that these rules and restrictions are different for gatherings of people of more than 1000]

How far away can we fly ?

At Heliviz we only operate within the regulations defined by the Civil Aviation Authority. The restrictions for operation are to fly within 400 feet in height and 500 metres horizontal distance and we must always be within the pilot’s line of sight (VLOS). In reality we rarely need to go anywhere near those distances to get you the shots required and we find safe practice is to assess the conditions and risks of individual scenarios. If you want to work outside these distances, we can apply for an individual safety case to the CAA.
*Insured with £5 million cover.

What about safety ?

Safety is paramount, a full safety assessment will be completed upon instruction. We are required to operate no closer that 50m from any person, vessel/vehicle or building outside our control.  We can not fly over public roads, pathways buildings or public spaces that are not under our control.

How long can we fly for?

Depending on weather conditions we can operate for around 12 to 15 minutes per battery. Battery replacement is quick, we can be operational once our safety checks have been completed.
