When the PFD declutters, what is the result?

• A. It reduces information by hiding some data
• B. It increases information density
• C. It dims the screen
• D. It keeps only essential information visible

Answer: (D)

Decluttering the Primary Flight Display is about prioritizing what matters most during flight. By removing or hiding non-essential data, the display becomes simpler and easier to read, so the pilot can focus quickly on the critical cues needed for safe control. The result is that only essential information remains visible, reducing cognitive load and helping faster, more accurate decisions in busy situations.

Hiding data is part of the process, but the best description of the outcome is that essential information stays visible. It isn’t about dimming the screen, and it doesn’t necessarily mean the total amount of information increases; it means the important information stands out when non-critical items are removed.
