<<object>> [Logical View::AIXM::AIXM
Features::Airspace]
Definition
The role of the component in the airspace geometry. If the geometry of an airspace
is composed of single volume, then the attributes of this association class may be
left empty.
Properties
operation CodeAirspaceAggregationType A code indicating how the
component participates in
the aggregation, such as
addition, subtraction or
intersection.
operationSequence NoSequenceType A number indicating the
order of the component in
the aggregation.

Layer]
Definition
The portion of airspace between two specified vertical levels.
Properties
upperLimit ValDistanceVerticalType Upper limit of the block. The
data type also allows a
special non-numerical value
"CEILING", meaning "the top
of the airspace. This can
useful in the case of
Airspace that have a nonconstant
upper limit.
upperLimitReference CodeVerticalReferenceType A code indicating the
reference for a vertical
distance. Two series of
values exist: 1) real distance:
from GND, from the MSL,
from the WGS-84 ellipsoid 2)
pressure distance: QFE,
QNH, STD.
lowerLimit ValDistanceVerticalType Lower limit of the block. The
data type also allows a
special non-numerical value
"FLOOR" meaning "the
bottom of the airspace". This
can useful in the case of
Airspace that have a nonconstant
lower limit.

AirspaceVolume ^
<<object>> [Logical View::AIXM::AIXM
Features::Airspace]
Definition
A defined volume in the air, described as horizontal projection with vertical limits.
Properties
upperLimit ValDistanceVerticalType The vertical position of
the airspace ceiling.
upperLimitReference CodeVerticalReferenceType The reference surface
used for the value of the
upper limit. For example,
Mean Sea Level,
Ground, standard
pressure, etc..
maximumLimit ValDistanceVerticalType When specified, the
maximum limit overrides
the upper limit, in those
parts of the airspace
where the upper limit is
situated below the
maximum limit.

used for the value of the
maximum limit. For
