Post Global = Much Bigger Flying Space = Less ATC Coverage
I want to keep it simple & sweet.
Calculating decent and approach path how you want it is great but not realistic. It’s been quite a challenge to calculate the perfect decent as stated by many threads. Approach coverage is little to none on TS1 at even major airports because either there is too little traffic or too much traffic to control. In real life, approach routes and altitude is always directed by ATC.
Create AI Bots which play the role of Approach ATC. Assigning altitude, speed and heading as you proceed to your destination. The directives are influenced by airport charts, airspace traffic, emergency requests, etc.
Disclaimer - This request is only for the approach frequency. This is because it is very practical for it to be controlled by AI. Tower & Ground frequencies don’t have the need to be operated by AI as there are already a unicom frequency which help pilot’s communicate effectively.
