Overview
- The campaign began in January and is slated to run into mid-February across Germany.
- Specialist pilots fly at 30–40 km/h and approach masts and conductors to within a few meters for high‑resolution imaging.
- Findings are reviewed after each route, with serious defects such as broken insulators reported immediately for repair.
- Exact flight times and locations can change due to weather and the network’s length, with a broad list of NRW regions published.
- Amprion describes the aerial checks as a routine, legally required complement to ground inspections as scrutiny of grid security has intensified following the Berlin blackout.
