This is a really nice piece of software, that appears to be the chosen pushback for the upcoming FF A320,
What's more, I have just discovered, although i realise that i might be slow, you can use Betterpushback entirely without leaving VR. I have mapped the Start Pushback Plan, Stop Pushback Plan, Start Pushback and Stop Pushback to a hat on my Warthog joystick and it works perfectly.
The plan screen can be seen without dropping back to the Sim window, so this is awesome.
It is currently in beta, so is a free download. I've used it successfully on the Aerobask Panthera/Eclipse, Zibo 737 and SSG 747-800, although i am sure that it will work with others too. Go on, give it a try.
