Sonicbum is right.
ULLI is the only airport in Russia which uses QNH.
And yes. All the charts still have QFE and QNH values given.
It is a testing phase. All others work with QFE but more and more give you QNH if you ask them.
Even RNAV approaches are possible on a few airports if you ask for it.
I presume, flying and out of Russia about 20 times a month this was just a missinterpretation of the numbers on the charts.
Flying on QNH and reading the QFE values or vice versa.
The biggest problem is that you fly down to FL50 on QNH and then you have to transition to QFE. Close to ground, stress and "out of a sudden" a different altitude reading procedure/measurement.
Also the EGWPS does will not be triggered if you dont touch the altitude numbers in the FMS, like changing the airport elevation to 0 just your altimeter will show 0 upon landing. Plus, you need to set all other values in the FMS to QNH. Never use QFE in the FMS
