Hello Proudprivate!
The answer for your question - there are different minimas. You can apply for a lower minimum on the standart LDE approach 26 giving your exact aircraft performence data (climbe rate in the mapp single engine, etc.). The data is used by austro control to calculate your flight profile in case of mapp and as a result you are getting autorisation for a lower minimum. Additionally you have to do sim-trg to get this autorisation.
It is also nearly the same for the rnp rnav approach 26 which has presently the lowest possible mnm as the mapp is not turning back to the east but going straight over the rwy along waypoints to the west. To get approval by austrocontrol for this your aircraft must be rnp 0.3 approved. If you are interested just check aip austria ad lowi 2-18 and 2-22
