Hi NS...
The FMC track miles to go change with each alteration of flight plan, with the final vectors taking circa 7 miles off the FMC value, they can't be relied on. The argument then comes back that they should leave us on the RNAV arrival, but even those 7 miles save fuel so I wouldn't like to loose the opportunity of being more efficient. We spend so much time saving 5kg here, 15 kg there doing things like reduced flap approaches, uplifting a few kg less clean water to make the aircraft lighter that these procedures as far as I can see are a thoughtless waste.
I believe this 'point merge' could work efficiently, but it just isn't designed well at Oslo taking into account their traffic flow levels. To be 30nm abeam the field firing downwind in the wrong direction and no1 to land is mad
BTW, I have no beef with the controllers in OSL (they are good and very helpful), they are just implementing what they are given. I do have MAJOR problem with the folk who designed the system...
