The infamous "fly by". A pain in the neck and potentially dangerous too.
Of course if you knew ANYTHING about procedure design, you'd realise what a stupid statement that was
Go read the definitions for 'fly by' and 'fly over'
Only potentially dangerous if you don't know wtfwhn
Remember that when enroute we navigate to RNP5 - we must remain within 5nm of the route centerline. Thus the aircraft can at any time be up to 5nm to one side of the ATS route and still be considdered to be navigating to the required accuracy.
Which means that you remain within 5NM for 95% of your route ..... sometimes (for 5%) you could actually be MORE than 5NM off track (legally
)
