Ministry of civil aviation

For sure is not for aviation. If anything they are a hazard that is documented in aviation charts and procedures. they are most likely transmission towers for radio and TV since they require the height.

Not different from non-Airbus planes as the safety standards are set by aviation authorities (FAA in the US). If you do not have their minimal safety equipment, you cannot fly.
