When would a special flight be conducted to investigate a potential problem?

A special flight to investigate a potential problem is conducted specifically when there are indications that a leak may be present, such as pressure drops, meter readings, or other relevant data. This proactive approach allows for quick identification and assessment of potential hazards that could affect the integrity of the pipeline and the safety of the surrounding environment.

Routine check-ups generally do not trigger special flights but are part of regular monitoring processes. Maintenance schedules focus on scheduled upkeep and repairs rather than responding to immediate potential problems. Additionally, conducting flights at the beginning of every month would not be a sufficient reason for a special flight since not all months may show signs that necessitate immediate aerial inspections. Thus, the decision to conduct a special flight is directly tied to specific indicators of potential issues, making it critical for timely response and effective management of pipeline safety.
