OK for day, but no night textures on the buildings and the ground night colour seems not quite right. Lots of textures could probably of been combined better to reduce drawcalls, so may be a bit stuttery on some systems. KMIA lite airport not very good, but it's not that expensive so don't expect too much.
The flight planning aspect of this program is good. It is a good advance over older softwares for planning your regular routes and saving them for later. I would suggest that the claim here of a 'large database of supported aircraft' is an exaggeration. Many common aircraft have no listing to be able to plan fuel, and it is even worse if you try to integrate it with Topcat to get take-off and Landing data. I would encourage the vendor to specifically list supported aircraft prior to purchase. It is not practical for average simmers to create brand new aircraft types. If you fly anything other than the most popular boeing, I would suggest you check forums to see if your aircraft is supported. The planning side only is probably not worth the price. You will want the fuel planning aspect too.
