There of course, is no prohibition against having two altimeters. One
set to QNH (field elevation) the other set to QFE (zero on the ground).
This is how American Airlines operated for decades. QFE is also the
standard in Russia and China.

The Chinese must have some pretty special altimeters if this applies to
all their airfields, including those in Tibet: Bangda airport in eastern
Tibet is at 14,219 feet AMSL.

Bangda has an 18,000 ft (5500m) runway and, I gather, needs it. I've
heard that the pilots must be on oxygen for takeoff and landing.
