What does NO GPW indicate in the HUD?

• A. No warnings available on the system
• B. PGCAS is selected with no warnings available
• C. Gears are not deployed
• D. Flight path is obstructed

Answer: (B)

The correct answer indicates that PGCAS (Pilot Ground Collision Avoidance System) is selected, but there are no warnings available to display. This situation can occur when the system is operational and monitoring the aircraft's flight path for potential ground collision threats, but it does not have any alerts to communicate to the pilot at that moment. This can happen if the flight conditions are safe and no immediate threats are detected. In contrast, the first choice suggests a generic lack of warnings, which does not specifically refer to the PGCAS context. The third choice about gears not being deployed does not relate directly to the HUD indication discussed. Lastly, the option regarding the flight path being obstructed usually correlates with potential warnings being issued, rather than suggesting no warnings at all. Thus, the nuances of PGCAS and its functionality in providing warning information make the second choice the fitting answer in this context.
