You got me there, but we mostly just double the altitude and add 10-25 miles, depending on possible winter tailwind, even with the slick new pressurization (now digital!). In the dash 50, we might triple the altitude to lose. I'm just a bit lazy, can't speak for the others.
Except for VOR/LOC/GS-capture, without automation in a 100-122 seat two-person c0ckpit (even with the now fairly tight airfoil pneumatic system), we are too busy to worry or care about making the altitude and/or 250 knots with just a few miles to spare, in a general sense, flying three different series of Jurassic "steam-gauge"/'water-klok' planes.
