Random 777 questions, part 1
Given old age I can only guess I'd be suspecting maybe winds (the point Uplinker made)/ or, and I'm clutching at straws here - programmed descent speed vs. programmed cruise speed - does it routinely happen if you transition from Econ cruise to Econ descent?
However, since anti-ice is normally only used when it's cold - well below the rating corner point for the Takeoff rating range - not everyone bothers to take a performance debit for anti-ice for Takeoff. Max Climb/Max Con are a different issue.
Some models permit dispatch with an EAI valve locked open (which can happen when it's pretty warm), but that's typically handled via the MEL.
I know VNAV has it's quirks but FWIW I had few thousand hours on the T7 and can't say I ever saw what you describe happen as a matter of routine.

I imagine not everything is in a checklist and some aspects of the operating the jet require the pilot to, well, be a pilot.
Don't know if this applies to the 777, but on the 787:
"If there is a complete loss of flight control signalling, direct wiring from the flight deck to the stabilizer and a spoiler pair allow pilot control of pitch using the alternate trim switches and roll using the control wheel."

Weird question, but still…
What is exact size of a small pitch rectangle on PFD (in degrees)?
In other words: What will be the pitch angle, if I just touch the 5 degree line with rectangle, then, if I keep inline the upper edge of the rectangle and the 5 degree pitch line?

Vnav influenced by wind and temperature variation?
