What Parameter/Units for Amosphere/Alt?

#1
Hey guys,

Yep.. Me again.

What would the parameter and unit of measure be for 'altitude pressure' measure of the atmosphere in the aircraft?


Cheers,

Bill,

Depending on which country Altitude indicator you build.

STRUCT LATLONALT Returns the latitude, longitude and altitude of the user aircraft. SIMCONNECT_DATA_LATLONALTstructure N -

PLANE ALTITUDE Altitude of aircraft Feet Y -

INDICATED ALTITUDE Altimeter indication Feet Y -
KOHLSMAN SETTING MB Altimeter setting Millibars Y -
KOHLSMAN SETTING HG Altimeter setting Inches of Mercury, inHg N -

BAROMETER PRESSURE Barometric pressure Millibars N -
SEA LEVEL PRESSURE Barometric pressure at sea level Millibars N -

PRESSURE ALTITUDE Altitude reading Meters N -


Is this what you are asking? You will need to do all the calculations if you want true altutude.

Hey Ron,

Actually, I think its atmospheric 'pressure' outside the aircraft. I'll have to research that. I was hoping it was a common use data field. (Didnt realise there were that many variables).

Many thanks. (Off to read some more in the Garmin manual).

If you want to know current pressure in atmospheres, use

(A:Barometer Pressure, atm)
