Task 14.3 - STS vs. PDRA - Choose the right path
This assignment invites the group to analyze the differences between STS and PDRA and apply the knowledge to hypothetical scenarios.
Learning materials:
Available text, paper and pens. Can be done at a table or in group work.
Activity:
Discuss key differences:
- Application process: STS requires a declaration, while PDRA requires an application to the CAA. What does this mean for the operator?
- C marking: STS requires a C5 or C6 labeled drone. PDRA provides flexibility as long as the operator documents that safety requirements are met. Why is this flexibility important?
Scenario analysis:
Divide the group into smaller groups. Each group considers the following situations and decides whether STS or PDRA is most appropriate and which specific template (e.g. STS-01, PDRA-S02, PDRA-G01) is suitable.
Scenario A:
An older, non C-marked drone (7 kg) is to be used for VLOS pesticide spraying over a controlled field, close to - but not over - densely populated areas. Need 10 m contingency area.
Tips: Rate PDRA-S01.
Scenario B:
A new C6-branded drone will conduct BVLOS inspection of power line in sparsely populated area, with visual observers. Maximum altitude: 100 meters.
Tips: Rate STS-02.
Scenario C:
A large, powerful drone (not C-marked, 2.5 m) will be used for long-range surveillance in a very remote, sparsely populated area. BVLOS, 140 meters altitude, with multiple observers.
Tips: Rate PDRA-G01.
Discussion:
- What determined the choice between STS and PDRA in each scenario?
- How do the different PDRA-G categories (G01, G02, G03) provide extended capabilities compared to STS - especially in terms of distance, height and area?
- Both STS and PDRA require approved training and passing the STS exam. Why is this common requirement important, even with different technical requirements?
- Discuss ground and air risk reduction measures (M1 and M2). How are these used differently - or equally - in the scenarios you analyzed?
