Hi Oskar,
I want to underline the argument of Supera380. When planing a route I'm always planing an alternate, too. I'm sometimes testing what to do, when a failure occurs and I have to divert to another airport in the vincity of my actual position. So, I would be very happy when you would recover this function.
I want to use the opporunity, to thank you for the excellent product an your decision supporting X-plane.
