Does the software take into account airport altitude above sea level when determining airplane ranges? I mean, if I operate out of ADD, which is 7700 ft high I got lower range as in fact is in real world?
Many thanks,
Claudio
Yes, the airport altitude is taken into account in fuel usage calculations for example (ie. plane starts climb from the true airport elevation instead of sea level always).
However for range calculations.. I fail to see the correspondance - unless it actually is runway length (performance) limited. But anyway, takeoff thrust requirement variations based on elevation and runway length etc are not modelled, as that would be going into senseless small details already.
Understood and agreed. Only it should indeed be considered cause it generate significant performance drop in real world. I make just a quick example: Ethiopian just opened its flight to YYZ, which is a mere 6217 NM, with 77L but still it has to stop at FCO for refuel. This I guess in not modeled in the game. Is it?

No, all runways are sufficient, and the loss in performance due to altitude is not in...
This would actually make 707-220, VC-10, B741B, etc. really have a point, because you'd have to use them as unavailability of the others. E.g. the 707-220 just uses 100kg fuel less than the 707-120 and adds 200NM, not much of an effect, but IRL it was specialized on H&H (Hot and High) operations. This also made the VC-10 such a success.
Also the 747-100B was specially equipped for such airports, so was the 747SP. These planes yet only make limited sense in the game :/
Anyways, that would just be some "senseless small details", as said priorly.
cheers
Sometimes IRL there's a limit on the rolling speed of the wheels. When in hot & high, the air is much less dense than otherwise, therefore you need more speed in order to produce lift. Imagine a MTOW 77L in H&H for a 6,000nm route... :P
