The PIC is responsible for the preflight walkaround.

The FAA 9even though this was not in the US jurisdiction) has since required
that any time a static port or pitot tube is covered, that it has a
high-visibilty (red) streamer attached and a notation of the condition is
made in the aircraft record so as to insure its removal prior to flight.

Nope. The cabin pressurization system only indicates differential pressure
between the exterior and interior of the aircraft, and cabin pressure
altitude. A fast-thinking flight officer could WAG at the outside altitude
at best by this, but by this time he's got too many bells and horns going on
to allow time for even that.
