In AEO you get the red LIMIT light with gong at 75% TQ ( T/P2 ) and an steady engine exceedance for >80%/10sec. If you are OEI , you can pull more ( 86/125/128% ) MCP or time limited without the above mentioned light/tone at 75% . Thats what i meant with "change to OEI mode" . So there must be some information going to the FLI to decide whether ist OEI or AEO?
