Technical Analysis

Safety Technical Analysis

In Europe, open category drones are required to have a class marking. The class marking ensures that the technical safety of the drone meets the required standards.

For the specific category, the UAV only needs to have a class marking if it is predestined to operate under a standard scenario. Otherwise, the SORA defines what the minimum technical requirements are for each SAIL. It is important to ensure that the drone used meets these requirements before being placed on the market or used for a specific operation.

There are several methods of analysing the risks of a system. We can help you perform the analysis that best suits your needs in order to prove the technical safety of your drone system.

You want to improve the safety of your UAV ?


The aim of the Functional Hazard Analysis is to identify the different types of failures and their consequences for each function of the UAS.


The Failure Mode and Effect Analysis dissociates the different possible failures for each component and analyses their effects on the entire UAS.


The "Fault Tree Analysis" uses the results of the two previous analyses and allows to reveal possible 'Single Point of Failure' and to draw a conclusion on the safety of the system.

CE Marking

CE marking is mandatory for all electronic products placed on the European market, including drones! Wrongly, some drones are assembled with CE components without re-certifying the system. CE marking of the final product allows to prove its conformity to european directives.

In order to obtain a CE marking, the product must have a declaration of conformity as well as a technical file according to the european directives. We are able to carry out the required tests and prepare the necessary files to obtain the marking.

In need of an EASA design verification ?

Class Identification Label

Class markings are specific technical requirements for UAVs. They do not replace a CE marking but are an additional proof of authorisation for the placing on the market for a use defined in the delegated regulation 2019/945.

In order to obtain a class marking, the UAV must meet the EN4709 standards.

Digisky solutions helps you target the most appropriate category and apply these standards.

EASA Design Verification

The design verification report issued by EASA ensures the conformity and technical reliability of one or more components of the UAV. 

Although the EASA design verification report is mandatory for some technical components from SAIL III onwards, it is advisable and preferable to have the pre-requisite verified directly with EASA even for lower SAILs. Thus, thanks to this report, the operator no longer needs to prove the necessary compliance and can obtain a specific category authorization much more easily.

Test and R&D

Thanks to our participation in the ASC-Laboratories, come test your drone and improve its performance and reliability. The test infrastructure allows to generate all environmental conditions in a precise and measured way.
