Interesting thread!
But if the flightplan says BE35 - it is not a Beech 350 (as I was called the other day) and I do not have access to all this fancy FMS gear.
I do have some toys up front and I was pretty good at maths (although completely cr*p at mental arithmetic), so it takes me a few minutes to work out how to "adjust speed to cross XXX at time YYY", ....... and when I stick the nose down I will accelerate (and overtake the Dash 8 in front of me) unless told to do otherwise.
I can hold 160 kts to 1000'/5nm and still turn off at the first taxiway.
Cheers
Dr
