We don't know yet. We would like to keep the current panel for now and we can't promise that the GPS device will be added to some of our default aircraft. This hasn't been decided yet. We'll see if it is received well from the JustFlight customers.
I sincerely applaud this positive development. Well done.
However, I respectfully suggest that your proposed approach to feedback might be worth re-considering.
Here's where I am coming from. To wait for feedback on the GNS instrument from the customers of an addon, will limit the feedback to those who buy that addon. It will not give you feedback from AFS2 users who have no interest in that particular addon.
Allow me to use myself as an illustration. I am a fan of AFS2, and an even bigger fan of JustFlight. BUT I did not buy the JustFlight Duchess because the aircraft itself does not appeal to me. Had you put the GNS in the Duchess, I would not be able to give feedback on it because I was not a customer of the Duchess.
In comparison, putting the GNS into an existing default aircraft will potentially open up the doors to feedback from all existing purchasers of AFS2. This would provide the possibility for greater feedback on the GNS, and also make it easier to tweak things (if needed) in the development of the instrument without implicating JustFlight if something does need to be changed.
I hope this makes sense. It is not a criticism, rather a different perspective on the proposed approach to feedback.
Keep up the positive development on these core features of AFS2. It is a very evident step in the right direction.
