Description
Add a new code list value MEDEVAC to the CodeFlightStatusBaseType.
Rationale for change
See https://aixmccb.atlassian.net/browse/AIXM-330
The AirportHeliport element in AIXM 5.1.1 does not have the ability to identify whether an airport/heliport can be used for medical evacuations. Because this is referring to a life-critical situation, a flight with this status may be prioritized by air traffic control. In addition, a need for coding the MEDEVAC value has been identified in the Digital NOTAM scenarios. New usage conditions based on the type of flight, such as needed for medical evacuation, should be supported in FlightCharacteristic.
Impact assessment
AIXM 5.1.1 files remain valid against the AIXM 5.2 schema as no value is removed. In existing systems, the the missing value can be coded prefixed with “OTHER:”, thus making it suitable for automatic conversion into proper values in AIXM 5.2.
AIXM 5.2 files that use the new values would be invalid against the AIXM 5.1.1 schema and will need to be converted, using the data type extension mechanism - prefix with “OTHER:”. The conversion is straightforward.
Change Proposal details
In the UML model, add the following code to CodeFlightStatusBaseType:
- MEDEVAC = “Life-critical medical flight”.
Mapping AIXM 5.1.1 to AIXM 5.2 (forward)
[MAPC-01] The following data conversion algorithm is proposed:
- For each FlightCharacteristic.status that has the value ”OTHER:MEDEVAC”:
- replace the value with “MEDEVAC”
Mapping AIXM 5.2 to AIXM 5.1.1 (backward)
[MAPC-01] The following data conversion algorithm is proposed:
- For each FlightCharacteristic.status that has the value “MEDEVAC”:
- replace the value with “OTHER:MEDEVAC”
