Hi all,i notice RCv 3.1 working not base on 3 to 1 rule of decent path, it instruct me to decent even i'm still 130nm away during cruising FL300. how many percent the tolerance for this function in RCv ?

i believe this is what you are looking for(Plane_Alt - arrival_elevation) / 210now what do you mean "how many percent the tolerance"?you can descend at 300 ftm per minute or 3500 ft per minute. your choice. as long as you make the crossing restriction, i don't really care. i do expect you to descend thoughjd

Hi, again, JD:When the type of aircraft is selected in the options panel, does that affect the ATC selection of the descent profile timing? Other characteristics?

no

Strictly altitude dependent. And, starting a flight down 130m out that's at cruise AOA FL300 is not unrealistic. Very normal and common.
