• B. AGCAS OFF
• C. GCAS INOP
• D. HUD FAIL

Answer: (A)

When the PGCAS (Pilot Generated Collision Avoidance System) or AGCAS (Automatic Ground Collision Avoidance System) is inoperative, the HUD (Heads-Up Display) indicates this in a specific manner to alert the pilot. The display of "NOGCAS" in the top left of the HUD serves as a clear and concise message to notify that the Ground Collision Avoidance System is not operational. This is crucial for situational awareness, as it informs the pilot that they should not rely on the automated features that would typically help in preventing ground collisions. The option "NOGCAS" accurately reflects the status of the system, directly communicating that the AGCAS functionality is not available. Therefore, it emphasizes the need for the pilot to exercise increased vigilance and manual oversight due to the lack of that safety feature. Understanding these alerts is essential for safe operation, ensuring pilots can make informed decisions in critical situations.
