The context is the Airport Collaborative Decision Making (A-CDM) concept as defined in Airport CDM Implementation Manual v4.

In A-CDM it is important to allow A-CDM Partners to set the value of some milestones when necessary.

The classical example is to allow the Aircraft Operator or the Ground Handler to set the Target Off-Block Time (TOBT) that indicates what is the target time for the aircraft to be ready for off-block.

Not any value can be accepted. There may be many business rules for validating the value. As for example: value cannot be in the past, value can no longer be changed, too many changes, etc.

Setting the TOBT value is possible at many stages during the A-CDM process, as early as Milestone 2 (EOBT-2hr) up to and including Milestone 11 (Boarding starts).

The Business Logic may involve validations such as:

• not accepting values in the past
• not accepting a new value too close the existing one (there is a minimum change involved)
• Limiting the number of changes after TSAT has been issued.

protocol configuration

HTTP Messages will indicate the payload content type using the content-type header

HTTP Messages that transport compressed payloads will use deflate/gzip/exi as expressed in the content-encoding header  (compression ratio is around 20%)

HTTP will use the chunked transfer encoding and indicate this in the transfer-encoding header.

HTTP will use the status header to indicate the status of the response using a code and corresponding meaning phrase. (see exception handling)

HTTP post method is supported

security

Server authentication based on  X.509 certificates

Client authenticates based on HTTP Basic

TLS1.2

Cypher Suites: AES_128_GCM_SHA256, AES_256_CCM

exception handling

The services make use of the standard HTTP 400 error [Bad Request] in any of the following cases:

• The request is for an unsupported release
• The request is not a well-formed XML
• The request is a well-formed XML but it is not valid with respect to the XSD (i.e. it does not conform to the type and attribute names defined in the XSD and documented in the reference manuals). Examples of causes for invalid XML documents are:
  • Unexpected element or attribute
  • Element order violation
  • Incorrect primitive value
  • Unexpected enum value

operation

setTOBT

The setTOBT Service Operation receives the Target Off-Block Time for a specific flight. The operation returns a confirmation of the validity of the provided Target Off-Block Time taking into account these business rules:

• Not accepting values in the past
• Not accepting a new value too close to the existing one (there is a minimum change involved)
• Limiting the number of changes after TSAT has been issued

input

TOBTSettingRequest

Message which provides the Target Off-Block Time value of a specific flight.

output

TOBTSettingResponse

Message which responds the validity of a previously sent TOBTSettingRequest message.

error

operation

The deleteTOBT Service Operation receives a request for deleting the Target Off-Block Time for a specific flight. The operation returns a confirmation of the validity of such request taking into account this business rule:

• Not accepting request affecting a flight with no Target Off-Block Time set yet.

Service messages

input

TOBTSettingRequest

Message which provides the Target Off-Block Time value of a specific flight.

output

TOBTSettingResponse

Message which responds the validity of a previously sent TOBTSettingRequest message.

error

The model is published as an XMI file that can be imported in Sparx Enterprise Architect.
