Emergency Engine Shutdown C/L
This symbol (+) will be used to indicate a concurrence item, meaning that you must point to the specific item (example - power lever) and say "Left power lever idle, concur?" IP will say "Concur" then you will pull it to idle. This is to ensure you are not pulling the wrong levers in your haste.
