What does the “MAGENTA” line indicate on a GPS?

The MAGENTA line on a GPS indicates the intended route or flight plan. This line is a visual representation that guides pilots along their pre-planned path from departure to destination, highlighting waypoints, airways, and other navigation points along the route. It allows pilots to clearly see their flight plan, making it easier to follow and navigate.

This function of the MAGENTA line is crucial for situational awareness, helping pilots maintain the correct course and making necessary adjustments during the flight. While there are other elements in the GPS display that may show position or terrain information, the specific identification of the MAGENTA line as the flight plan route is essential for effective navigation.
