I get responses from the first officer until I line up on the runway for take off and press the Sec button for RTO review. I get no responses from that point on in the flight.Richard

Hello Richard,Does the Rejected Takeoff Brief play?The backup is to 'left click' with your mouse directly on the RTO REV text on the Departure/TO Briefing page.If you hear the Rejected Takeoff Brief, you should be in Takeoff mode.Thanks,Bryan
