I do want to use the A320NX, as this seems a far more realistic simulation than the native A320 NEO in FS2020. If ever the Fenix A320 is released, I might have a look at this one as well.
Doesn’t that feel a bit strange? I mean, you press a button so you expect to have a reaction. Why would you program the action on the release of the button? I’m curious for the reasoning behind this.
By the way, I just found a very handy trick with the Behaviors window. If you hover over a control in the sim until it becomes blue, and you press “CTRL G”, the Behaviors window shows immediately the data related to that control. This means you don’t need to search in these long lists with sometimes very ambiguous names. This means that I can use the codes in MobiFlight, but I can always cross-check in the sim afterwards. Reason is that I’m a bit suspicious about the quality of the data provided in MobiFlight. As I understand, everybody can contribute. But that means that there is no real quality check. So there might be a lot of mistakes in there. Better not to rely 100% on that data.
