What will display at the bottom left of the HUD if PGCAS or AGCAS is inoperative?

• A. GCAS INOP
• B. NOGCAS
• C. AGCAS OFF
• D. DTC ERROR

Answer: (A)

The correct answer, GCAS INOP, signifies that the Ground Collision Avoidance System (GCAS) is inoperative. This notification is crucial for pilots as it directly impacts the aircraft's safety management systems. It alerts the crew to the absence of this critical function, which is designed to prevent loss of control situations by providing warning prompts about potential ground collisions. The design of a Heads-Up Display (HUD) ensures that any inoperable system like GCAS is clearly indicated so pilots can take necessary precautions or implement alternative safety measures while flying. Having this information readily available on the HUD allows pilots to make informed decisions regarding the operation of the aircraft, ensuring they are alert to any additional risks associated with the inoperative system. Other options do not accurately represent the typical notifications for inoperative GCAS systems. For instance, terms like NOGCAS or AGCAS OFF may suggest a status, but they are not standard indicators found on the HUD. Similarly, DTC ERROR would pertain to a discrete technical communications error rather than the operational status of the collision avoidance systems.
