Reduced Vertical Separation Minima (RVSM) was due to be introduced to the airspace of Afghanistan, Kazakhstan, Kyrgyzstan, Mongolia, the Russian Federation, Tajikistan, Turkmenistan and Uzbekistan on 17th November 2011. It is notable, according to IFALPA, that while the majority of these States will be using Flight Level (feet) based altimetry, Mongolia has opted for a metric application.

Accordingly, IFALPA has published two Briefing Leaflets using data obtained
from the affected States:
