Description
Additional values are introduced for the types of AirspaceActivation.activity to allow for more precise data coding and alleviating information loss, when regularly value OTHER is used.
Rationale for change
See https://aixmccb.atlassian.net/browse/AIXM-226.
It was identified that the current list of values of data type CodeAirspaceActivityType may be insufficient.
A big part of the AirspaceActivation.activity(ies) included in this proposal add the missing activities that can be referenced to the ICAO Doc 8126 - NOTAM Selection Criteria. The second part of the proposed activities includes those indicated in SAA.ACT/NEW Digital NOTAM scenarios and provided as a feedback, of common applicability. The proposed activities have been used as “OTHER:...”
Despite the fact that this change proposal tries to resolve a large part of these identified issues, it will certainly not satisfy all data providers/users. Further clarifications are expected in future versions of AIXM.
The table below provides the overview of justification for the values included in this change proposal:
| Proposed new airspace activity values | Definition | |
|---|---|---|
ACFT_MASS_MOVEMENT | Mass movement of aircraft | ICAO Doc 8126 - NSC |
CAPTIVE_BALLOON_KITE | Captive balloon or kite | ICAO Doc 8126 - NSC |
DEMOLITION | Demolition of explosives | ICAO Doc 8126 - NSC |
DISASTER_RELIEF | Disaster relief | Examples provided in JIRA review of common applicability |
FORMATION_FLIGHT | Formation flight | ICAO Doc 8126 - NSC |
MODEL_FLYING | Model aircraft flying | ICAO Doc 8126 - NSC |
NIGHT_VISION_OPS | Night vision device operations, aircraft lights out. | Examples provided in JIRA review of common applicability |
SAR | Search and rescue | Examples provided in JIRA review of common applicability |
SKY_LANTERN | Sky lantern | Examples provided in JIRA review of common applicability |
SMOKE | Presence of smoke | Examples provided in JIRA review of common applicability |
VOLCANO | Significant volcanic activity | ICAO Doc 8126 - NSC |
Impact assessment
There is no impact on existing implementations as the current AIXM 5.1.(.1) data remains fully valid against AIXM 5.2. No values are removed from this list.
When receiving data from AIXM 5.2 implementations, current AIXM 5.1(.1) systems will be able to map back the new values into OTHER:... values, as described in the mapping rules further in this document.
Change Proposal details
In the UML model:
- In the data type CodeAirspaceActivityType
Add following values:
- ACFT_MASS_MOVEMENT, definition = “Mass movement of aircraft.”
- CAPTIVE_BALLOON_KITE, definition = “Captive balloon or kite.”
- DEMOLITION, definition = “Demolition of explosives.”
- DISASTER_RELIEF, definition = “Disaster relief.”
- FORMATION_FLIGHT, definition = “Formation flight.”
- MODEL_FLYING, definition = “Model aircraft flying.”
- NIGHT_VISION_OPS, definition = “Night vision device operations, aircraft lights out.”
- SAR, definition = “Search and rescue.”
- SKY_LANTERN, definition = “Sky lantern.”
- SMOKE, definition = “Presence of smoke.”
- VOLCANO, definition = “Significant volcanic activity.”
The following UML class diagram shows the modified list of values. This includes the change introduced with CP AIXM-401, which has replaced UAV with UAS.
Mapping AIXM 5.1.1 to AIXM 5.2 (forward)
[MAPC-01] The following data conversion algorithm is proposed for AirspaceActivation.activity values:
- Replace “OTHER:ACFT_MASS_MOVEMENT” with “ACFT_MASS_MOVEMENT”
- Replace “OTHER:CAPTIVE_BALLOON_KITE” with “CAPTIVE_BALLOON_KITE”
- Replace “OTHER:DEMOLITION” with “DEMOLITION”
- Replace “OTHER:DISASTER_RELIEF” with “DISASTER_RELIEF”
- Replace “OTHER:FORMATION_FLIGHT” with “FORMATION_FLIGHT”
- Replace “OTHER:MODEL_FLYING” with “MODEL_FLYING”
- Replace “OTHER:NIGHT_VISION_OPS” with “NIGHT_VISION_OPS”
- Replace “OTHER:SAR” with “SAR”
- Replace “OTHER:SKY_LANTERN” with “SKY_LANTERN”
- Replace “OTHER:SMOKE” with “SMOKE”
- Replace “OTHER:VOLCANO” with “VOLCANO”
Mapping AIXM 5.2 to AIXM 5.1.1 (backward)
[MAPC-01] The following data conversion algorithm is proposed for AirspaceActivation.activity values:
- Replace “ACFT_MASS_MOVEMENT” with “OTHER:ACFT_MASS_MOVEMENT”
- Replace “CAPTIVE_BALLOON_KITE” with “OTHER:CAPTIVE_BALLOON_KITE”
- Replace “DEMOLITION” with “OTHER:DEMOLITION”
- Replace “DISASTER_RELIEF” with “OTHER:DISASTER_RELIEF”
- Replace “FORMATION_FLIGHT” with “OTHER:FORMATION_FLIGHT”
- Replace “MODEL_FLYING” with “OTHER:MODEL_FLYING”
- Replace “NIGHT_VISION_OPS” with “OTHER:NIGHT_VISION_OPS”
- Replace “SAR” with “OTHER:SAR”
- Replace “SKY_LANTERN” with “OTHER:SKY_LANTERN”
- Replace “SMOKE” with “OTHER:SMOKE”
- Replace “VOLCANO” with “OTHER:VOLCANO”
