GCXO-EFHK: long flight/great experience

Featured Replies

Don't take a full load of passengers / cargo and fill in the cruise winds. A 100+ knot westerly jet stream will do quite a bit for your fuel use.KLM does KSEA-EHAM in one go when taking delivery of their new 737s though they don't take any passengers in that case of course.

Sounds like a nice route - longest so far for me in the NGX is EGCC - HESH and return in the same day.Heading that way myself tomorrow - EGNT GCTS.Enjoy!Carl Beeby

How do you guys do such long flights from NYC to Copenhagen without refueling? If I try that, I'll get "INSUFFICIENT FUEL".
The trick is to not always believe the messages the FMC gives you about destination fuel remaining. I'm no RL pilot but I've found that if I do my fuel calcs correctly and I get the "Using RSV fuel" message during prep, once airborne and without exception the FMC recalcs fuel usage and stops complaining -- especially when you factor in winds and a couple of step climbs to chase optimum fuel usage.For example on my GCXO-EFHK flight I calculated that, given winds, initial altitude and 2 steps, I'd need 36,500 lbs in order to have roughly 6000 lbs on arrival. I set 5000 lbs in the FMC as my reserve but during prep the FMC complained that I was only gonna have 4,300 at Helsinki. I knew from experience that the FMC's initial calc is wrong. So, when I got airborne I entered the info for the first step and that was enough to push the estimated destination fuel remaining up to 5,300. With a good tail for the second 3 hours and another step climb, I arrived with 5,800 lbs, which was more than enough to get me to my alternate at Turku, Finland.The worst that could have happened would be a re-fuel at Copenhagen or Stockholm. Over the Atlantic, Iceland can be used as a fuel stop if you've seriously miscalculated. Call me a nerd, but his is the kind of stuff that makes simviation fun :)

ESSA-LEMG 4h20min ESSA -3° and snow.LEMG +18° and sun, the airport doesn't even have a de-icing facility (actually I wouldent say that ESSA can handle de-icing either :( )
