If the navigation source is FMS, the active leg is magenta and all other legs are blue.

• A. Active leg: Magenta; Other legs: Blue
• B. Active leg: Blue; Other legs: Magenta
• C. Active leg: Red; Other legs: Blue
• D. Active leg: Yellow; Other legs: Blue

Answer: (A)

In FMS navigation displays, the color magenta is used to highlight the leg that is currently active, while blue is used for the other legs of the flight plan. This color contrast helps you quickly see which segment you are actively flying and which segments are upcoming or not yet active. So when the navigation source is FMS and the active leg is magenta with all other legs blue, the statement “Active leg: Magenta; Other legs: Blue” matches the standard color coding. Colors like red or yellow aren’t used here to indicate the active leg, and assigning blue to the active leg would not visually emphasize the current segment.
