ABSTRACT:
The present apparatus relates to nonvolatile fault flags for use in aircraft. The term "flag" refers to an electromechanical indicator which displays a human-readable signal which identifies a fault. A fault is a malfunction occurring in the aircraft. The term "nonvolatile" refers to the feature that the signal is not lost when electrical power is terminated to the indicators. In addition, apparatus are provided for displaying the first, and only the first, fault signal received by the indicator, and for the prevention of triggering of the indicator by spurious signals.
