Default Increasing power required with altitude.. what's a good plain english explanation?

Also, not that it would matter to a non-pilot, but IAS obviously matters
for keeping best range speed for instance.


How so?

Best L/D occurs at a particular angle of attack. This corresponds fairly
well to indicated airspeed.
