I downloaded and installed the NGX in 24 hours (welcome to Indonesia/the jungle), but to my surprise there is no display of the exterior model when looking at the airplane from outside. I'll try to reinstall FSX these days, will let you know if the problem persists. In my first two flights, at cruise I tried to change some options in the PMDG Setup in the CDU. At that point FSX did not only crash, but my whole computer shut down (not even the correct shutdown procedure, but the power just went off). Anyone else having this problem? My third flight was more successful, but I noticed some behaviour which I've not seen in the real NG: - With the A/T engaged before takeoff, pushing TO/GA will switch on the FD's during takeoff roll, even if they are not switched on. In the NGX I cannot use TO/GA if I did not switch on both FD's - When using APP mode (after VOR/LOC capture, before G/S interception), selecting the second A/P should switch this on (not yet engaged) and not transfer A/Ps like in the NGX - On the descent I noticed that if the speed drops too low, the FMA (for A/T) changes to "FMC SPD", which is correct. However, after gaining the correct speed, the thrust was set to idle again, and I expected the FMA to change back to "ARM". This did not happen. - When creating a waypoint on the LEGS page in the CDU based on coordinates, the FMC correctly creates a waypoint (WPT01 in this example). However, I am not able to use this waypoint to create another (eg WPT01360/40). This example returns "not in database". Could you tell me if this is the programmed behaviour or if this might be bugs? Thanks
