Specific Category

General Rules

 

If you cannot comply with one of the obligations of the OPEN category (including horizontal safety distances), you fall into the SPECIFIC category.

The SPECIFIC category is based on the SORA methodology. It is important to note that Luxembourg does not have national standard scenarios and that the national standard scenarios of other countries are not recognized in Luxembourg.

An operational authorization is mandatory for all operations in the SPECIFIC category excluding STS *.

 

SEVERAL POSSIBILITIES EXIST:

  • Standard scenarios * (STS) - applicable from 03.12.2023

A standard scenario (or STS)  is a defined type of UAS operation in the SPECIFIC category (see below), for which precise mitigation measures have been determined after a risk assessment carried out by the 'EASA. Compliance with the conditions of a standard scenario can be declared to perform operations in the SPECIFIC category (no operational authorization).

 

  • Predefined risk assessment (PDRA) - applicable from 31.12.2020

A Predefined Risk Assessment (or PDRA) is a defined type of UAS operation in the SPECIFIC category (see below), for which mitigation measures have been determined after a risk assessment performed by EASA. The PDRA is very similar to the STS but the differences with the latter are left to the discretion of the competent authority. The PDRA therefore requires an operational authorization to carry out operations in the SPECIFIC category.

 

  • SORA (Specific Operation Risk Assessment) - applicable from 31.12.2020

The SORA methodology is a systematic procedure to analyze a concept of operations (CONOPS), identify the associated risk level, mitigation measures as well as operational safety objectives (OSO) to enable safe operations. The development modalities of the SORA are available at AMC1 in article 11 of Regulation 2019/947.
