What does a flashing 'EOCS' annunciation on the HUD indicate?

The flashing 'EOCS' annunciation on the HUD signifies that the engine out compensation system has engaged. This system is designed to assist the pilot in maintaining control of the aircraft in the event of an engine failure. By utilizing aerodynamic controls and adjusting the flight parameters, the EOCS helps ensure the aircraft remains stable and manageable despite the loss of power from an engine.

Recognizing this annunciation is critical for pilots, as it triggers specific procedures that need to be followed to ensure safe handling of the aircraft. Engaging the engine out compensation system is a crucial response to an engine failure, as it directly addresses the operational demands imposed by the situation. Understanding this system's functionality helps pilots prepare for emergency scenarios and ensures they are equipped to take appropriate actions immediately.
