What does the Multipurpose Display Group provide?

• A. The airspeed indicator
• B. The engine RPM
• C. The fuel quantity
• D. The radar altitude on the HUD

Answer: (D)

The Multipurpose Display Group is the part of the avionics that feeds the HUD with essential flight data, and it specifically provides radar altitude on the HUD. Radar altitude is the height above the ground measured by the radar altimeter, which is crucial for low-altitude flight and terrain awareness because it reflects what’s immediately beneath the aircraft, not just altitude above sea level. Other data like airspeed, engine RPM, and fuel quantity typically come from different instruments or displays, so the MDG’s role here is to present the radar altitude on the HUD for precise height information during critical phases of flight.
