During what situation should you contact the FLM?

Contacting the Flight Line Manager (FLM) is essential when you have confirmed GPS anomalies. Such anomalies can significantly affect the safety and efficiency of flight operations by potentially leading to navigation errors or miscommunications between pilots and air traffic controllers. Reporting these anomalies allows for immediate investigations and corrective actions to be taken, ensuring that any adverse effects on aviation safety are addressed proactively.

In contrast, confirming NAVAID usage, reporting routine operations, or situations when no issues arise typically do not require FLM contact because these situations do not present immediate concerns that could compromise safety or operational integrity. The focus on GPS anomalies highlights the need for vigilance in areas of navigation technology, making it imperative to communicate such issues promptly.
