UAS Certification Consulting

Obtaining UAS certification can be a challenging process. Our experience and understanding of current developments in CS-UAS, CS-LUAS and EASAs Special Conditions for Light UAS, means that we can help you plan and implement the certification strategy you need to be a market leader in UAS manufacturing.

UAS Certification

Carriage of Dangerous Goods by UAV

Rules around the carriage of Dangerous Goods (DGs) by unmanned aircraft continue to evolve. Our detailed understanding of DG regulations has already helped operators in the UK obtain CAA approval for transporting specific categories of DG during BVLOS delivery operations.

CAA Approved Dangerous Goods Training

We provide CAA approved training relevant to the handling and transport of Dangerous Goods by unmanned aircraft (a prerequisite to obtaining approval to carry DGs).  The training is customised to the type and classes of Dangerous Goods that you intend to transport and whether you are 'shipper' or 'operator' of DGs. 

Training can be conducted online or, Covid regulations permitting, face to face.

Temporary Danger Area Applications

At present, most BVLOS operations require the use of segregated airspace.


The applications process for establishing a TDA can be quite complex (e.g. UK CAA CAP 1616 'Airspace Change') but our experienced team are able to help you get your TDA set up with a minimum of delay and headache.

What our clients have said:

“Across Safety has provided excellent continuous support on all regulatory aspects of our vehicle development programme. They have helped us to define a regulatory strategy that matches our long-term global business plans, while simultaneously managing all the detailed regulatory work for our sub-scale vehicle testing. We have been impressed by the ability of Across Safety to navigate the regulatory complexity of developing a high-altitude unmanned airship, which does not normally fit within the existing rules of most countries."

Director of Vehicle Operations, Avealto, United Kingdom

“Across Safety has provided excellent value for us when we’ve needed external support the most.  Thanks to their specialist knowledge and expertise in obtaining unmanned aircraft regulatory approvals, Skyports has been able to secure BVLOS operational authorisation from the UK CAA to deploy our delivery drones for the NHS in the Scotland as part of the response to COVID-19, including becoming the first drone operator in the UK to be granted permission by the CAA to carry dangerous goods by unmanned aircraft.  We cannot recommend Across Safety enough and they will continue to be our go-to unmanned aviation consultants in the future.”  Head of Regulation, Skyports, United Kingdom

"Across Safety was the right choice for us. With their assistance, and expertise in the SORA method, we have been able to obtain the first drone light show approval in Switzerland using a swarm of up to 100 specially equipped LED drones.

They were proactive and easy to work with from our base in Switzerland using a combination of online meetings and email. We happily recommend their consulting services."
