Dumb Reg question

The regulations says:

no person may act as pilot in command of a pressurized aircraft
(an aircraft that has a service ceiling or maximum operating
altitude, whichever is lower, above 25,000 feet MSL)

I don't see any way to read that parenthetical as anything other than
a *definition* of "pressurized aircraft". I don't understand what you
think it means.

(g) Additional training required for operating pressurized aircraft capable
of
operating at high altitudes.

They are defining the conditions under which you must acquire additional
training. If you wanted to operate a
pressuized aircraft that had a service ceiling of 20,000 ft, then no
additional training is needed.
