It can be a fraction of that if you don't mind yet another portable device
cluttering your cockpit:

If we are talking about why airplanes have vacuum systems then we need to
keep the discussion to certified equipment -- other options may work but if
they are not certified then the FAA will require a vacuum system for legal
IFR.

system? As I mentioned earlier, I have not yet managed to find a single
example of a fatal accident caused by a vacuum-pump failure in a
fixed-gear
plane flying IFR. There must be one or two, but it does not appear to be
a
significant risk.

I think part of this may be related to how the accidents are classified.

For example, there are a number of examples each year of IFR airplanes which
simply suffer inflight break-up for unknown reasons; these could well be due
to vacuum pump failure.

What's the FAA position on venturi-driven instruments?
