Couple of questions about Career mode

I have a few questions about Career mode and would really appreciate insights/solutions.

  1. Random Airpstrips

How long do I have to fly to random airstrips in the middle of nowhere? I have a VIP charter company and done countless missions and none of them have me flying to a proper airport. Are airliner missions the only one originating and ending at airports?

  1. Mission is IFR but ATC is broken

ATC seems broken as of now for IFR missions. Before a mission, in the EFB the mission is set to IFR and I have my approaches selected but ATC does not inform me altitude for descent. In the middle of the flight it just says ‘resume own navigation’. I never cancel IFR nor do I ever miss a transmission.

  1. AI does not respond to ATC

In my settings under Assistance I have turned on “AI Radio Communications (ATC)” but the Copilot/AI does not respond to ATC even once on any mission. This means I can not be away from my desk on a long flight because I will end up missing ATC transmissions during transition.

  1. UNKN / No Night Time missions

I operate on the West Coast of the US and usually sim during the night. As of now, no missions have a red dot on them meaning they are not real-time. The only time I get a red dot is if I change the time to day. And most of them are LIFR for destination airports. When they are not real-time, UNKN is displayed next to the departing and landing airports, does this mean the sim is forcing VFR regardless if I file a IFR plan?

  1. Custom flight plan

I like to get real-world flight plans from SimBrief as much as I can. Since there is no way to import a plan directly, I end up entering waypoints manually into the EFB before the flight but there is no place to enter altitudes for each waypoint. I can only enter cruising altitude but where do I enter descend phase altitudes for ATC? Is that something I need to do inside the aircraft and then re-file the flight plan with ATC? I fly the Vision Jet so any help would be appreciated.
