[AIXM-538] Airspace activity reviewed list of values

ID:	AIXM-538
target version:	AIXM 5.2
version:	1.0
last updated:	08 AUG 2022
status:	APPROVED

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

[FWD_MAP_1:1] Data mapping is possible and no data loss occurs when data is exchanged from a system (A) that uses AIXM 5.1.1 for output towards a system (B) that uses AIXM 5.2 for input.

[BWD_MAP_1:1] Data mapping is possible and no data loss occurs when data is exchanged from a system (B) that uses AIXM 5.2 for output towards a system (A) that uses AIXM 5.1.1 for input.

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”
