All I just recently bought Simtouch and I have released a new version of maps for Prepar3d & fsx.
It has multimaps to use such as Google maps,Bing maps,Yandex maps and ope street maps.
It will should you aircraft and all other aircraft in real-time. It has built-in TCAS system and it will show all surrounding airports up to 20 NM. Have a look and see what you think www.simtouch.eu
