Attributes
|
|
CODE_TYPE
[Type]
mandatory
|
|
|
A code indicating the type of Airspace. E.g. UTA, CTA, TMA, CTR, OCA, Advisory Area, Limited Area, Uncontrolled Airspace, etc. .
|
|
|
Notes:
|
|
|
It seems that a number of countries use the 'traditional' airspace types like FIR, CTA, etc. and others just use the 'class' instead.
|
|
|
Rules:
- If CODE_TYPE is 'ICAO', 'ECAC', 'CFMU', 'IFPS', 'FIR', 'FIR-P', 'UIR', 'UIR-P', 'CTA', 'CTA-P', 'OCA', 'OCA-T', 'UTA', 'UTA-P', 'TMA', 'TMA-P', 'NO-FIR', then the airspace may not be part of an AIRSPACE_ASSOCIATIONS of type 'TIME-DIST'.
- This attribute is non-updateable. This means, for example, that an FIR cannot change into a sector or a danger area and vice-versa.
- If CODE_TYPE has the value 'FIR' or 'UIR', than CODE_LOC_IND is mandatory.
- If CODE_TYPE='CLASS', then attribute CODE_CLASS is mandatory.

Domain:
CODE_TYPE_AS
|
|
CODE_ID
[Coded identifier]
mandatory
|
|
|
A published identifier associated with the airspace. Typical examples are the ID of the Danger, Prohibited, Temporary Segregated Areas, etc.
|
|
|
Domain:
CODE_ID_AS
|
|
TXT_LOCAL_TYPE
[Local type designator]
optional
|
|
|
A type designator used locally for a particular airspace category.
|
|
|
Notes:
|
|
|
For example, the type 'HPZ' is used in some States in order to designate 'Helicopter Protected Zone' (established around oil installation zith helidecks). In the interest of international harmonisation, such airspace may be recorded as type 'PROTECT' [Airspace protected from specific air traffic] with the activity 'TFC-HELI' [Helicopter/Gyrocopter traffic]. In addition, the local type designator 'HPZ' may be recorded using this (TXT_LOCAL_TYPE) attribute.
This attribute does not have a predefined list of allowable values.

|
Domain:
VAL_DIST_VER
|
|
UOM_DIST_VER_UPPER
[Unit of measurement [upper limit]]
optional
|
|
|
The unit of measurement expressing the upper limit.
|
|
|
Rules:
- If the unit of measurement has the value 'FL' or 'SM', then the attribute CODE_DIST_VER_UPPER must have the value 'STD' (standard pressure)..
|
|
|
Domain:
UOM_DIST_VER
|
|
CODE_DIST_VER_LOWER
[Reference for lower limit]
optional
|
|
|

Domain:
CODE_DIST_VER
|

|
|
UOM_DIST_VER_LOWER
[Unit of measurement [lower limit]]
optional
|
|
|
The unit of measurement expressing the lower limit.

CODE_DIST_VER_MAX

VAL_DIST_VER_MAX
[Maximum limit]
optional

|
|
The value of maximum limit. 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.
|
|
|
Notes:
|
|
|
Usually, the maximum limit is expressed as distance from the ground while the upper limit is expressed as an altitude or as a flight level. In mountainous areas, due to large variations of the ground level inside the airspace, the maximum limit becomes locally higher than the upper limit.
|
|
|

VAL_LOWER_LIMIT
[Lower/upper separation]
optional
|
|
|
The limit between the upper and the lower airspace.
|
|
|
Notes:
|
|
|
1) The concept of 'upper airspace' is not uniformly applied through the ECAC area. Some States declare Upper Flight Information Region(s) - UIRs. Other States just declare Flight Information Region(s) -FIR, but also indicate that there is a separation between the upper and the lower airspace inside the FIR. In order to accommodate these two situations, VAL_LOWER_LIMIT may be specified only for airspace of type 'FIR'. If there is an UIR above, this value is equal to the VAL_DIST_VER_UPPER value (the upper limit) of that FIR.
|
|
|
Rules:
- This value may be specified only if CODE_TYPE = 'FIR'.
