FSDreamteam has updated GSX to version 2.7.3. This version introduces pushback with multiple waypoints. The new custom pushback uses hand placed nodes to create routes, similar to an AFCAD creation. The nodes are created ingame, using a combination of key presses and mouse clicks. It is fairly simple to use, and up to 9 waypoints per pushback route can be added.
The developer released the update along with a short video explaining how to use the new pushback creation tool.
The update is free to all GSX customers, works in both Prepar3D v4 and FSX and is available through the FSDreamteam updater. If you do not own them already, GSX and its Level 2 expansion can be bought for respectively €34 and €27 on Simmarket.
