What is the Field of View (FOV) of the HUD?

• A. 40 deg wide, 30 deg high
• B. 30 deg wide, 20 deg high
• C. 50 deg wide, 25 deg high
• D. 25 deg wide, 15 deg high

Answer: (B)

The Field of View (FOV) for a Head-Up Display (HUD) is essential in aviation, as it determines how much information the pilot can see simultaneously without needing to look away from their primary sightline. In this context, the FOV of 30 degrees wide and 20 degrees high is commonly accepted in many aircraft designs for HUDs, as it provides a balance between visibility of vital flight data and the pilot’s ability to maintain awareness of the outside environment. This configuration allows pilots to see essential information, such as airspeed, altitude, and navigation data, all while still being able to visually monitor their surroundings, which is critical for safe flying. The specified dimensions create an optimal window for situational awareness, reducing the chances of missing important external cues while accessing relevant HUD information. When considering the other potential options, they either offer a wider or narrower FOV, which may not align with the design and operational efficiency principles commonly accepted in avionics. Thus, the 30 degrees wide and 20 degrees high specification is recognized for enhancing pilot performance without compromising exterior visibility.
