What does the HOT AIR FAULT light indicate when it illuminates amber?

• A. Leak detected
• B. Overheat detected
• C. Overpressure detected
• D. Underpressure detected

Answer: (B)

The illumination of the HOT AIR FAULT light in amber signals that there is an overheat condition detected within the hot air system. This is an important safety feature designed to alert the crew of potential thermal hazards, indicating that the temperature in the hot air duct has exceeded normal operational limits.

Recognizing this alert allows the flight crew to take appropriate action, which may include adjusting system settings or considering alternative procedures to manage the situation effectively. The condition could result from various factors, such as malfunctioning equipment or blockage within the system, underscoring the need for diligence in monitoring and reacting to these alerts during flight operations.
