What action is required to eject from the aircraft?

The correct action to eject from the aircraft is to pull the ejection handle. This handle is specifically designed for initiating the ejection sequence, allowing the pilot to safely exit the aircraft in emergency situations. When the ejection handle is pulled, it activates the ejection mechanism, ensuring that both the pilot and the seat exit the aircraft rapidly and safely.

The other options are associated with different controls and emergency procedures within the aircraft but do not initiate the ejection process. The firewall shutoff handle is used to cut off fuel flow to the engine, while the green ring is associated with a different feature that does not relate to ejection. Placing the PCL in idle is a preparatory step in some emergency procedures but is not the action that directly leads to ejection. Understanding the specific purpose of each control is crucial for effective emergency response in-flight.
