Thanks for the reply, it is quite helpful. From your own experience, if the aircraft is not going to overshoot the track, can you say how close most aircraft normally pass by a FLy-By? Most aircraft in our airspace will be 250 knots or less and on a SID or STAR and I guess what I am asking is what can the controller expect the aircraft to do when it is approaching a Fly-By? Can you clear an aircraft to the FLy-By point for instance although it is not actually required to Fly over it? In some of our procedures, a FLy By is the start of an approach and it is only the final approach fix and a waypoint beyond the runway after a go-around that are designated as Flyover points. We are in the process of redesigning our airspace and introduce SID/STARS and RNP5. Should one clear an aircraft to the Flyover via the Fly -By or what do you do in such a scenario?
Thanks, your reply is much appreciated.
Cheers
