Which display group shows the radar altitude on the HUD?

• A. Primary flight display
• B. Multipurpose display group
• C. Standby instruments
• D. Electronic flight bag

Answer: (B)

Radar altitude is the height above the ground shown by the radar altimeter, and the HUD is fed by a display group that aggregates flight data for quick glance readability. In this system, the multipurpose display group handles the data that the HUD projects, including the radar altitude. That makes it the most appropriate source for this specific readout on the HUD, since it’s designed to present flight-critical information beyond just the basic attitude or barometric altitude. The primary flight display usually emphasizes barometric altitude and attitude as its core metrics, while standby instruments serve as a backup set of mechanical or independent indicators. The electronic flight bag is used for charts and documentation rather than HUD data. So radar altitude being shown on the HUD through the multipurpose display group aligns with how the cockpit’s data streams are organized to deliver essential terrain-height information when flying at low altitudes.
