I think a lot of things involve technique. For example speeds. We use to climb the 727 at Mzch .82 to cruise, level off, then reduce power to maintain the mach. 82. Descent ws at red line. But, "back then", fuel was cheap. In fact, it was, if I uinderstand correctly, the cheapest thing the ocmpany had as far as operating expense went.
Spoilers. Not only to increase descent. I have occassionally used them for that on FS, but more often I use spoilers to reduce ias to 250 to cross 10,000 on the descent. It's easy- pop the spoilers and raise the nose a bit- ias drops rather quickly and the descent continues. lr.

In FS "technique" helps .... BUT SOMETIMES .... employing a technique can lead one away from reality too given the limitations of FS. There are means (only we've discovered some of these at a fairly late stage) .... in regard to FDE writing .... by which descent, rather than airspeed reduction, may be prioritized in response to the inflight deployment of wing spoilers. Just don't pop the wing spoilers inflight on the DC-8's though .... that's all .... and that's a "real world", and not an FS, restriction. ON DC-8's the wing spoilers are for ground deplyment "ONLY" .... on touch down/landing. History records a couple of DC-8 accidents (one of which was particularly nasty) that resulted from the inadvertent inflight deployment of the wing spoilers ....
