Trying to learn, past the office hours, how to fly the airplane effectively without VNAV gizmos is frowned upon. Who is the magenta child here?

But then I should know better than to feed a troll.

But then again no reason to overly complicate things.
What I tell my trainees, is to plan approaching 10.000í at 40 track nm out, high speed. Then you have just the distance needed for slow down and manuevers.

With the RNP-AR procedures, there is a tick that shows TOD, likely put there so the pilot doesnt wonder why the thrust suddenly pulls back to idle!

But sometimes you get shortcuts, and if you know ATC is going to give you one, logic says you should act accordingly.

And anyway I'm a pilot, not a passenger sitting at the pointy end.

😁 Wouldn't work on the 'bus, design rules the aircraft cannot do what is not commanded.

Highly evolved tech might allow commanding a descent at a specific point (TOD) by selecting a cleared to altitude and observing the result.

Like I said, not on the 'bus. Design rules, no self-action.

That can be debated

Uncommanded pitch change at programmed acceleration altitude? Don't overspeed your flaps please.

In fairness, if it does that, it SHOULDN'T overspeed the flaps.

Fair call, there's also the pitch down at G/S capture or FINAL APP and pitch up shortly after LAND. Some of ours have auto TCAS, but it's a taboo until training is completed.

Youíre complicating what is relatively straightforward. And I promise you other experienced pilots are reading this and shaking their heads also.

No troll here, just a captain that hears FOís complicated BS on a daily basis. Anyway, get back to your riveting dialogue and I look forward to hearing your wisdom on the flight deck tomorrow 😉👍🏼

Descent Profile

Such fun to see professional pilots attempting to master arithmetic which an 11-year old can solve in their head.

Yeah, some people do need to heed the KISS principle a bit more. But there is no harm in discussing it for input.

For me and my type, distance times three works fine, then adjust for weather by simple logic... tailwind? Go down earlier. And remember that there is usually no ban on level flight during any descent or arrival . So donít stress it if you are off by a bit or too early on descent. Stay on the safe side. Also learn to say ďunableĒ to ATC if you are unsure if you can do what is asked.
