Hi, Having difficulty activating FO prompt to start his Take Off flow which includes PA telling FA's to be seated for departure. I'm arming autothrottle about a minute from the runway and nothing happens. Am I doing something wrong? Thanks Marty

Hello Marty,Make sure the Beacon (Anti-Collision) light is on; that is a necessary condition.The FO will turn the beacon on during his Before Start Flow.After the 737 loads, make sure the beacon is in the 'off' position. It should be in the off position if you've loaded the 737 correctly using the Cessna method described in the manuals.Hope that helps,Bryan
