For how long will the ST READY annunciator remain illuminated if activated, regardless of the PCL position?

The ST READY annunciator in the T-6A aircraft is designed to remain illuminated for 3 seconds when it is activated, regardless of the Power Control Lever (PCL) position. This time duration is set to provide the pilot with a clear indication that the system is ready and operational. The consistent timing ensures that pilots can reliably anticipate the annunciator's behavior, allowing for better situational awareness and decision-making during critical phases of flight. This feature is essential for maintaining consistent training and operational standards, and understanding its function is crucial for effective aircraft operation.
