I wonder how altimeters for airliners work, given
the change that happens at 36152' - or indeed the
U2 altimeter. Must be some interesting stuff inside.

Typically the DADC's are corrected for known issues/errors in the
pitot/static system of the specific type aircraft it is installed in,
as well as the "change"s you've noted.
