Hello everyonel,
Airspaces represented graphically in the map of FSX have this structure.
Excerpt from the SDK:
BoundaryStart
This element is used to indicate the start of a Boundary volume. This element is not allowed to contain other data and must be terminated with ‘/>’.
<BoundaryStart
lat="41.45240683"
lon="-87.01929230"
minimumAltitudeType = "UNLIMITED"
altitudeMinimum="235.00079346"
maximumAltitudeType = "UNKNOWN"
altitudeMaximum="240.00079346"/>
minimumAltitudeType Default is MSL.
UNKNOWN
AGL
ABOVE_GROUND_LEVEL
MSL
MEAN_SEA_LEVEL
UNLIMITED
altitudeMinimum Minimum altitude in meters.
maximumAltitudeType Default is MSL.
UNKNOWN
AGL
ABOVE_GROUND_LEVEL
MSL
MEAN_SEA_LEVEL
UNLIMITED
altitudeMaximum Maximum altitude in meters.
What I do not understand is that instead of the BGL defautl the "minimumAltitudeType" and "maximumAltitudeType" are quoted in "AGL". While the value is in reality AMSL (ABOVE MEAN SEA LEVEL) only in a few exceptional cases refers to AGL.
For example, if the upper and lower vertical limit in a given CTR is from FL145 to FL245 in the file of BGL Default is indicated as follows:
BoundaryStart
lat="41.45240683"
lon="-87.01929230"
minimumAltitudeType = "AGL" <<<<<--------
altitudeMinimum="4419.6M"
maximumAltitudeType = "AGL" <<<<---------
altitudeMaximum="7467.6M"/>
While the value is in reality AMSL (ABOVE MEAN SEA LEVEL) only in a few exceptional cases refers to AGL.
Does anyone know the reason why the team FSX used to indicate the altitude of the upper and lower level in AGL?
This for me now is just a small problem for one a little bigger.
Thank you for your attention and sorry for my bad English.
