Which HUD element helps estimate the next field of view when adjusting vantage?

• A. Altimeter
• B. Brackets on HUD graphics
• C. Compass rose
• D. Flight plan display

Answer: (B)

Understanding how your view will change as you move your vantage point is central here. When you adjust where you’re looking, you want a quick way to predict what will fall into your peripheral and central sight on the HUD. Brackets on the HUD graphics provide that predictive frame: they act as reference markers that stay tied to the display, showing where the edges of your future field of view will be and roughly where a target will appear as you shift perspective. This lets you estimate the next view quickly without searching around the screen.

The other elements don’t serve this purpose. An altimeter measures altitude, not what you’ll see in the display’s field of view. The compass rose indicates direction, which is useful for orientation but not for predicting viewing angles. The flight plan display shows route information, not how the scene will frame when you change vantage.
