I note that a VLM exec is
quoted as saying they want to get 300 hours a month utilisation from the aircraft. That's - to say the least - pretty ambitious.
Not necessarily.
The SU95 has been happily operating 300+h/m with Aeroflot and Intejet with a 99+% technical dispatch reliability.
Armavia allegedly had a number of issues with theirs, however it was both the first production model off the line and handed back to UAC shortly before they went bankrupt, so presumably they worked out they couldn't afford it/didn't have the right route structure for it.
The design and economics look competitive against the CRJ/ERJ, and it would be nice to see Russia's first serious project get off the ground to the full extent.
