A3SG-IER-08 Obstacles Data Exchange

Owned by FERNANDEZ SANCHO Pedro
Last updated: 2022 May 17

Abstract

This requirement describes the information exchanged by an AISP in order to support the dissemination of information related to obstacle data publication.

Actors 

The following actors are involved in this information exchange:

  • The Information Provider is the AISP
  • The Information Consumer is any other stakeholder including other AISPs as well as Civil and Military stakeholders. 

Purpose 

This exchange address the need to disseminate information relative to obstacle data.

Information 

The information exchanged relates to obstacle data expressed as aeronautical information features.

The specific list of aeronautical features aligns with those identified as part of the "Obstacle Data Set" of the ICAO data set features.

Interaction 

The information is expected to be exchanged between the identified stakeholders taking into account the following interaction characteristics:

  • The information exchange may enable filtering
    • by feature type and name. 
    • based on spatial, temporal and logical operators.
  • Information Exchange Frequency relates <<obstacle data publication cycle???>>

Non Functional Requirements

There is no non functional requirement identified.

Constraints 

This exchange of information is constraint to be performed as follows: 

  • Based on AIXM

Reference and Related Requirements

This information exchanged relates to the requirements stated by CP1 and the SDP as described here:

In terms of CP1

It corresponds with the following requirements associated to AIFS, but specialized to obstacle data :

A3SG-REF-002CP1/AF5.1.3AIFSOperational stakeholders R/T AIFSOperational stakeholders must implement aeronautical information feature on request; filtering possible by feature type, name and an advanced filter with spatial, temporal and logical operators … that support the exchange of the aeronautical information… as described in the deployment programme


In terms of SDP

It extends the information scope stated in the SDP to include obstacle data.  The AIFS requirements of the SDP are only focused on the AIP/SUP data:

A3SG-REF-018SDP/AF5.3AIFSAIFS purposeThis service supports consumption of published AIP and AIP SUP data

It covers functionality requirements stated in the SDP:

A3SG-REF-020SDP/AF5.3AIFSAIFS functionality

The provider of the aeronautical information feature service ensures that systems implementing the service:

• Shall allow the retrieval of aeronautical information features.

• May enable filtering by feature type and name.

• May allow advanced filtering based on spatial, temporal and logical operators.

It covers roles the roles stated in the SDP, taking into account that airports in the context of AIFS provide information when acting as AISP.

A3SG-REF-019SDP/AF5.3AIFSAIFS roles

The aeronautical information feature exchange shall be implemented by:

• AISPs that are the primary provider of the service

• Airports when aerodrome information is provided by an Airport

• AUs, ANSPs that are the primary consumers of the service and the information it provides
