Very impressive movie! Toward the end of the video I see you engaged A/P and LNAV and VNAV.  At that point the A/P commanded a power reduction and from a 4000 ft/min climb to a -500ft/min descend.  You then engaged FLCH.  Why was that? Was that due to the MCP ALT at that point? I hope the A/P didn't do that for no good reason.

By looking at the altimeter the VC gauge refresh rate is not bad but toward the low end.  But that may be the video itself?

Again, very good video.  The best presentation of this newly completed 757 that I've seen so far. thanks.  One more patch and I'm most likely buying this beauty!
