30W says it all.We use the straight in on this heading to establish as the most convenient (both in terms of R/T and workload) method for us, and (as expressed by the 'customer'
) the most expeditious routing.
The aircraft is continuously radar monitored and separation is maintained vertically from other traffic if required.Descent instructions (ie,on the G/P) are not given until well inside the protected area and anyway either due to interaction with other SID/STAR profiles or to the CDA requirement are not given until virtually the corresponding descent point on the G/P.
Let our retired brethren rest easy that safety remains assured
