Does our sim take into account Density altitude?

Recommended Posts

IF we are landing on high altitude airports, does the sim aircraft behave differently than landing at sea level?


Does out landing require a longer runway for takeoff and landing like in real life?


IS this an attribute of the sim or is it an attribute that needs to be coded in the add on aircraft? if so which addon aircraft take this into account?  Real air? PMDG? 


Which airport and which aircraft demonstrates this categorically? Any ideas?

If you're referring to air density variation with altitude, then yes, of course any half-decent flight simulator does model that.


On the other hand, among the general purpose flight simulators, only FlightGear models the variation of air density at altitude when there are ISA temperature deviations. Also, some non general purpose simulators (PSX and IL2 I think) model that.

That's why you see such lower RPM outputs and climbrates on normally aspirated engines at higher altitude airports. 


How detailed past a general sliding scale it goes (i.e. does it take temperature into account?) I don't know.
