Watch out below
Well for my two cents worth, As a Captain of a regional turboprop i thank God that there is a 500' buffer between me and a smaller craft be it fast or slow, i say this as all too common i have seen aircraft enter the curcuit at regional airports beneath me with no radio calls ,this after i have called at 25 nm and 10nm and when joining the curcuit.I tell you this that one day mark my words there will be a midair at a regional aerodrome between rpt and private aircraft,not only do you have aircraft not calling to avoid charges but unfortunately a great many pilots lack situational awareness when it comes to other traffic , especially when the target is travelling at 4 nm a minute on descent.
