Correct me if I'm wrong but engine runups are part of the mechanics'
pre-handover (of the aircraft) routine, right? It's after that that
the aircraft is towed on to the ramp and delivered to the pilots. I've
only ever seen runups being performed near uninhabited areas outside
hangars.

this is recreational.aviation.piloting.
just about all of us do our own runnups because we dont employ
mechanics. they are done just before takeoff.

do you do things differently where you live????

I guess I got my wires crossed in a way, as a pilot friend kindly
pointed out to me in private :\

I was thinking of the everyday scene that I see en route home, in the
Emirates hangars at a spot circa here

where some aircraft's engines get runup every other day by mechanics
standing around.

You appear to have been looking at maintenance runups of large turbojet
powered aircraft, which whould typically be run up following some types of
work having been performed--rather than prior to each flight.

OTOH, propeller driven aircraft, especially those with reciprocating engines
and magneto ignition, are usually run up prior to each flight--or at a
minimum prior to the first flight of each day. That may change within the
foreseeable future, as FADEC systems replace the manual mixture controls and
the traditional dual magnetos--so that computer diagnostics can be
continuously available without the need for the pilot to conduct a series of
tests and measurements. Then, only the propeller governor would remain on
those aircraft with neither fixed pitch propellers nor single lever engine
controls.
