PANSA Digital NOTAM Subscription and Request Service 1.0.0
Current JSON Original JSON

Abstract

PANSA Digital NOTAM Subscription and Request Service allows the service consumer to get aeronautical information in accordance with the Digital NOTAM specification. The aeronautical information conforms to the event scenarios that are supported by Digital NOTAM such as runway closures. The service consumer may subscribe to the service, specifying the event scenarios of interest. It is also possible to send a direct request to the service to get the aeronautical information. The information returned is in the form of an AIXM 5.1.1 message. This supports the integration of the latest information into an existing aeronautical information store in the various ATM systems.

PANSA

PANSA is responsible for air traffic management and navigation services in Poland. The key activities of the organisation include airspace management and ensuring safe and efficient flow of air traffic. Every day, the Polish Air Navigation Services Agency (PANSA) takes care of the safety of passengers of about 2 500 aircraft moving over Poland, and coordinates thousands of drone flights out of nearly 1 million registered in the PansaUTM system. The airspace we supervise and control covers more than 334 000 square kilometers and is one of the largest in Europe. PANSA is the only institution in Poland that trains and employs civilian air traffic controllers.

Operational Needs

Air traffic management is defined by ICAO as the "dynamic, integrated management of air traffic and airspace including air traffic services, airspace management and air traffic flow management - safely, economically and efficiently - through the provision of facilities and seamless services in collaboration with all parties and involving airborne and ground-based functions". Stakeholders involved in air traffic management need aeronautical data concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential for flight operations. This service satisfies this need by allowing clients to subscribe to event scenarios and to be notified when the aeronautical data described in the event scenario is affected. The aeronautical data can be used, e.g., in pre-flight information bulletins. It can also be used to improve decision making thus positively impacting the efficiency of their planning and flight executions, enabled through automatic data verification and graphical visualisation. The aeronautical data is also used in other systems such as those used for airspace reservations (ARES). A list of these is available in Appendix C. This service satisfies this need by offering the aeronautical data (in the form of event features) as regulated by ICAO Annex 15 - Aeronautical Information Services.

Information

The service shall expose the event scenarios found in Appendix B. These reflect the Digital NOTAM Specification.

The event scenarios use features that are in the Aeronautical Information Exchange Model (AIXM) 5.1.1 and the AIXM Event Extension.

The AIXMBasicMessage that is returned by the service shall contain an event feature and the related AIXM features and time slices.

Event-based filtering for subscription service

The subscription service allows a client to subscribe either to selected event scenarios or to the full event context. This supports both targeted event consumption and broader event monitoring according to consumer needs. The AIXM 5.1 data and digitalNOTAM are returned together with the referencing time slice, which contains the actual feature change (TEMPDELTA or PERMDELTA) and the underlying BASELINE of the feature change. This allows clients to receive the full scope of the DNOTAM.

PANSA AIM System
Queue Name

The queue name is represented exclusively by a UUID. This UUID is included as part of the AMQP broker address through which the connection is established. Queue name is generated by the system and is returned in Subscription reply message. AMQP Queue Name convention/pattern is:<uuid>

Duplicate subscriptions

Service consumer is responsible for creating subscriptions for selected/specific Digital NOTAM scenarios. The system allows service consumer to create multiple subscription with same filter.

Normal Conditions

The service behaviour is in accordance with the patterns detailed in Message Exchange Patterns: Identification Guidelines. A combination of an AMQP 1.0 implementation and an OGC Web Feature Service 2.0 Interface Standard implementation is used. Regarding message exchange patterns the service consists of- SYNCHRONOUS_REQUEST_REPLY - RESTful interfaces handle the subscription and request for Digital NOTAM.- BROKERED_PUBLISH_SUBSCRIBE_WITH_PUSH_MECHANISM - an AMQP 1.0 implementation handles the distribution of the messages. The behaviour of Digital NOTAM Subscription and Request Service Subscription Interface under normal conditions: - The service consumer sends RESTful request message to subscribe (subscription request contains valid filter)- The service consumer remains blocked while awaiting the reply- The service remains blocked while processing the reply- The service sends response message with AMQP Queue name, subscription filters and subscription status to the service consumer (subscription is by default created with status "PAUSED", i.e. subscription will not receive any Digital NOTAM messages yet)- The service consumer sends RESTful request message to activate subscription- The service consumer remains blocked while awaiting the reply- The service remains blocked while processing the reply- The service sends response message to the service consumer, informing about subscription status change The behaviour of Digital NOTAM Subscription and Request Service Distribution Interface under normal conditions: - event scenario is triggered, this causes change of aeronautical data in the system- the system generates Digital NOTAM message- the system distributes the message to AMQP Queues based on subscriptions and their stored filters (handled by AMQP Message Broker) - the service consumer connects to their AMQP Queue and consumes the message- the service consumer sends acknowledgement to AMQP Message Broker, the message is removed from the queueThe behaviour of Digital NOTAM Subscription and Request Service Request Interface under normal conditions: - The service consumer sends RESTful request message with WFS GetFeature query- The service consumer remains blocked while awaiting the reply- The service remains blocked while processing the reply- The service sends response message with data.

Technical messages

Implementation of SYNCHRONOUS_REQUEST_REPLY - RESTful interfaces handle the subscription and request for Digital NOTAM using REST API. BROKERED_PUBLISH_SUBSCRIBE_WITH_PUSH_MECHANISM- an AMQP 1.0 protocol uses technical messages to inform the service consumer about: update or deletion of AMQP Queue linked to subscription

OGC Web Feature Service

This International Standard specifies the behaviour of a service that provides transactions on and access to geographic features in a manner independent of the underlying data store. It specifies discovery operations, query operations, locking operations, transaction operations and operations to manage stored parameterized query expressions.

OGC Web Feature Service - Temporal Extension (WFS-TE)

The temporality extension has been developed in order to align the OGC WFS 2.0 and FES 2.0 standards with the AIXM 5.1.1 Temporality Concept. It allows retrieving data in AIXM 5.1.1 format via OGC WFS 2.0 requests.
