errrrrrr... not exactly the point here I'm afraid. At rotation, the pilot notices excessive control forces. (It is not THAT easy to break out any A/P) and no pilot in his right mind would want this scenario in even their worst nightmare, as was the case of AF in LOS. (In this case, due to a nice long runway, we had a coincident Vr/V1 , and the crew RTO'd !!!!!). No way would relying on breakout forces be acceptable to anyone in their right mind as a way of checking A/P engagement. As was posted by many in a related topic, don't mess with the MCP or anything else during the T/O, and 'live and die by your (E)ADI. (PFD in a 777).
