Mini UAVs on Civil Sky - New Risk Scanarios

While U.S. increase its strikes by large drone aircraft on suspected militants in Pakistan in the past few weeks to thwart terror attack plans in European countries, civil aviation authorities are warning for risks of mini UAVs at home land. 

With the increasing popularity of small, unmanned aircraft (20 kg or less), some of which can now be controlled by Smart Phones, the UK Civil Aviation Authority (CAA) has issued advice on using mini UAVs in built-up areas or when in proximity to people, property or vehicles. The CAA said it was important that owners of the aircraft understood the risks they pose, despite their small size, to other airspace users and also to individuals on the ground. The CAA pointed out that these devices are ‘aircraft’ and are therefore covered by regulations within the Air Navigation Order, which anyone flying them should be aware of. There have been a number of accidents in recent years, some fatal, involving model aircraft, and to avoid similar incidents and risk to third parties, operators of these new generation of unmanned aircraft should take great care when using them. Where such small, unmanned aircraft are fitted with surveillance cameras, they need permission from the CAA to operate within 50 metres of a person, vehicle, vessel or structure (not in control of the person in charge) and when operating over or within 150 metres of any area that is substantially used for residential, industrial, commercial or recreational purposes or open-air assemblies of more than 1,000 people.

Emergency services, and many commercial operators, are already using small, unmanned aircraft mounted with cameras, but are doing so with the full knowledge and authorisation of the CAA. All such flying is done within set distances from the pilot, who must also be able to clearly see the aircraft at all times to ensure safe operation and the avoidance of collisions.

Matt Lee, Head of Regulation Enforcement at the CAA, said: “Anyone thinking of buying a small, unmanned aircraft should be aware that whilst there is a lot of pleasure in flying one, they are not toys and they must be operated legally. In the wrong hands or used irresponsibly in built-up areas, or, too close to other people or property, they represent a very real safety risk. As well as the danger of being physically hit, there is also the chance of other accidents being caused through distraction, for example, if a car driver was to be surprised by something flying towards him. In the past we have seen people seriously injured or even killed by model aircraft and, now that small, unmanned aircraft are becoming more readily available and simpler to fly, we need to avoid any similar incidents.”
