Airbus A350 data update
New features
- Airbus A350 data update:
- A350-900ULR and A350-1000ULR added (these are just weight variants of normal -900/-1000 with added fuel tanks, but they are added as own models since they're marketed with the ULR name).
- Climb/descent performance and all fuel usage values updated (AirwaySim Performance Model v.2).
- Production launch and start dates updated.
- A350-1000 max passenger capacity updated (480).
- Range values updated.
- Cargo capacity values updated.
- Engine variant names clarified.
- New +15.0 tn MTOW weight variant for A350-900 added.
- New +8.0 tn and +11.0 tn MTOW weight variants for A350-1000 added.
- These updates are applied to all future game worlds, and also currently running History and the Future and The Age of Flight games.
- Airbus A330-900neo data update:
- Max passenger capacity updated (465).
Improvements
- Freighter/cargo aircraft conversions are now limited to a maximum number of simultaneous conversions per airline, scaled to your maintenance staff size, to prevent unrealistic mass-conversion of stored fleets.
