Which altimeter setting do you use when approaching an ex USSR Airport?
I was landing in Astana, below TL we decided to set Qfe at 4 Dme we were established and perfect VMC daylight the Egpws started to sound "TOO LOW TERRAIN", we disreguarded the warning and landed normally.
I reported it to my Tr.PH and he said that he had tha same warning when using Qfe because the EGPWS system works with altimeter setting and suggested me to use Qnh...
When you approach and land in Astana the ATC provide you with Qfe ( Qnh only on request ) but their clearances are issued in HEIGHTs ( example "descent to height 800 Qfe 998") so if you decide to use Qnh you have to do the maths by yourself to get the ALTITUDE ( height plus elevation ) and it's quite hard as long as you have to convert from meters to feets!!
