We happen to use Boeing for all of our initial and recurrent training so this little ditty was a result of one of those rec. training events. I did my "dearture briefing" as follows; I'll reject this take off for any reason prior to 80kts, between 80kts and V1, I'll reject for engine failure, fire, loss of directional control, and a windshear warning. etc. Well during that subsequent take off we had a generator drop off line at around 120kts. I rejected. During the post flight debrief the instructor reminded me that was not how I briefed the takeoff and in fact it was not a reason to reject the take off. Point well made.
We do call out 80kts and throttle hold on all departures, btw.
