[ok] range bug? B707
« on: August 01, 2015, 06:30:13 AM »
Departure    Helsinki - Vantaa, EFHK (HEL), Finland Finland    4121 NM    
via (tech stop)    Okayama, RJOB (OKJ), Japan Japan    4874 NM    
Destination    Auckland, NZAA (AKL), New Zealand New Zealand    4874 NM    
via (tech stop)    Okayama, RJOB (OKJ), Japan Japan    4121 NM    


Im flying this with B707-320B Adv. So, it is littlebit over its range. But interesting thing I noticed is that when it fly back Auckland to Helsinki via Okayama pax seems to be right 129. But when I take a look when it flies Helsinki to Auckland via Okayama (Helsinki - Okayama is oves 4800NM from helsinki) It can carry full 162 pax ?!
BUG?

flying west-east is usually shorter (in time) than flying east-west. look therefore at the flying times for each leg. more than the distance it is the flying time that determines the range!

Ok. How do you explain legs example Helsinki - Los Angeles and Backwards. Both legs no difference with pax - same reduce on both ways and the same plane..? ~4800miles allso

Maybe it's because of runway limitations? If the runway in Auckland is short, the aircraft can't carry full weight of both fuel and passengers.

because flying from Los Angeles to Helsinki is shorter (in time) than Helsinki-Los Angeles. Both the rotation of the Earth and prevailing winds help. On a transatlantic crossing there is often a one hour difference. As fuel is burnt by the minute and not per km this explains the difference in range.

Yep, but like I said, Helsinki to los angeles and back, both have same pax reduce. But why Helsinki to auckland and back are less pax in back? Maby sami could explain? Becaus, It should happening allso in Helsinki to los angeles route... Same wind thing should happening east to west, west to east.. It should not depend, where it happening, Us or Asia soil..

The game does not use flight time when calculating range when load restricted. It only uses distance of flight, length of runway and aircraft performance. If you see differing pax counts then it should be a runway limitation on one of the two legs on the offending route.

Not possible becaus shortest runway I use in the leg is 3000meters. Plane needs Runway requirement    2 730 m (@ MTOW)
here is some pictures.

And allmost the same distance compared to stopover airport in Helsinki - Auckland route.
How the Helsinki via Okayama to Auckland can eaven be 162 pax becaus Helsinki Okayama have same distance than Helsinki - Los Angeles (130 pax only)... ?


Helsinki - Los Angeles, same plane.
Both directions same pax - and actually less than 162... But the pax number stays same in both directions...

Maby the bug is this: The system ignores route lenght after stop (if you go via some airport) - it calculates just the first or last leg of it?

Example:

route 5000nm stop 1000nm. Problem is that 5000nm, and the plane can carry just 20 peoples.

Backwards 1000nm stop 5000nm = Full pax 200 peoples, system calculates just first 1000nm?


Not tested, just toughts...
