Cool! So if you lose your engine the plane helps you get back to the
ground quickly by extending the air brakes? Is there an override (for
those who fly over inhospitable terrain/water)?

The hydraulic pressure is probably provided by an electric pump

Ah...that makes a difference.

Furthermore, loss of pressure should only happen if there's a leak in the
system somewhere;

I can buy that (although my gear commonly "droops" after many checks) with
the emphasis on "should". (On farm equipment, the typical culprit is the
controlling valve.)

Is there a placard that says "Do not lose engine power in excess of max.
gear extension speed."?

There would be no need for such a placard.

Yeah, it looks like it would need to be "Do not leak hydraulic fluid in
excess of max. gear extension speed."
