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.
