So I have a quick question about descending. Should I descend before contacting the approach frequency, or should I remain at my cruise altitude and let the approach controller guide my descent? I know this may be a stupid question, but I just got to grade 3 and I’m flying expert server now, so I just want to know the proper procedure.
Edit: thanks guys for the support and help, but many of you have misunderstood the post. Maybe it is the title, or maybe you didn’t read the post, but I’m asking about the ATC part of descent, not the actual descent calculations and stuff. Still, thanks for trying to help.
