Yes I tried all of them.
1st try: closed all the apps from background. Starts Aerofly, I select 737NG and for airport I choose Singapore, initialising and crashes after some seconds.
2nd try: restarted the device, launches Aerofly, i select the same aircraft, this time, I selected Hong Kong, initializing and again crashes.
It’s strange, only those heavy aircrafts like 737, A320 and other heavy aircrafts like A380 only crashes while, I load from any of the HD airports. Small aircrafts like dash 8, baron work well without issues.
Regarding the unpopulated areas, yes, it works well. Even with those heavy aircrafts.
It’s only crashing at heavy or large airports like WSSS, KJFK and some places. It didn’t crash at NZAA, YSSY and some Australian airports . (as well as Mumbai).
