As my longtime relation to Russian hardware is known, I also have loaded down the AN 158 thanks to Alex post. For the moment I am still working on waking up the beast with the original panel. Good news: engines already running, Bad news: The PFD is not working as it should. Looks like this screenshot at AVSIM.SU:
The startup is not my problem, but the non-working PFD and AP is. The Samdim AN 148 panel for me looks bad. So I hope that the developers of the AN-158 will adress the problem of the PFD and the AP. They could have a very nice simulation then!
