Not sure what you are referring to, I'm talking more about the TCA [terminal control area]. I use all the nav tools to get where I want, WP input, TACAN, VOR etc, and as mentioned formulation speed/60=miles travelled per minute/into the distance you need to go=minutes to target [use cockpit stopwatch].
What I'm referring to is a more interactive ATC simulation and I'm happy to say so is DCS.
Thanks for the input.
