Altitudes

[TheLever]

Looking at the SimConnect SDK docs, specifically those for the simulation variables, I am trying to determine which of the many ALTITUDE variables will give me the altitude of a plane slated to standard pressure (29.92/1013.2). My understand of the following altitudes is given below:

• "PLANE ALTITUDE" - the altitude the simulator knows the plane to be at. Is that in any way related to pressure?
• "INDICATED ALTITUDE" - the altitude the pilot would see in the cockpit with reference to altimeter setting the pilot has set
• "PRESSURE ALTITUDE" - the altitude referenced to standard pressure

Are the above assumptions correct?

Thanks,

'Plane Altitude' is height above sea level
'Plane Alt Above Ground' is height above the ground beneath you (usually what you'd use in a radar altimeter)
'Indicated Altitude' is altitude derived from barometric pressure
'Pressure Altitude' is derived from standard ISA. See this explanation on how it's derived: https://www.flyingmag.com/guides/what-is-pressure-altitude/

Excellent! Thanks for the response
