LatinVFR has released AREX: Airport Regional Environment X North America for Microsoft Flight Simulator.
The package replaces the stock ground services at all airports in North America (Continental US and Canada) with more realistic service vehicles common to the area. The vehicles and catering trucks have logos for all major ground handling and catering companies. It is possible to select from nine Airlines: American, Air Canada, Delta, United, Jetblue, Spirit, Alaska, West Jet and Frontier.
Additional details include sounds for different vehicle engines, custom animations and pushback trucks depicting regional companies. AREX uses the default system of summoning ground services; no external apps or files are needed. It also has no negative impact on performance.
