Interoperability Program Interoperability Initiatives • Testbeds are fast-paced, multi-vendor collaborative efforts to define, design, develop, and test candidate interface and encoding specifications. These draft specifications are then reviewed, revised, and, potentially, approved in the OGC Specification Program. • Pilot Projects apply and test OGC specifications in real world applications using standards based commercial off-the-shelf (SCOTS) products that implement OGC Specifications. • Pilot projects help users understand how to best implement interoperable geoprocessing that meets their requirements for application, spatial data, and geoprocessing service sharing. • These projects also help identify gaps for further work. • Interoperability Experiments are brief, low-overhead, formally structured and approved initiatives led and executed by OGC members to achieve specific technical objectives that further the OGC Technical Baseline.

Use Cases SAA information Static Repository (NASR) query subscribe/un-subscribe SAA User Operational Repository (SAMS) SAA update notification Interoperability Layer OGC ® Copyright © 2011, Open Geospatial Consortium, Inc. 15
SAA Pilot Use Cases • Query for SAAs by – Spatial bounding box – Flight route filter (spatio-temporal) – Airspace feature property value (e. g. by lower/upper altitude) • Event Subscriptions and Notifications – – – Subscribe for flight route active schedules Get notified of airspace active schedules Get notified of schedule reservations/cancelllations Subscribe for SAA definitions/updates Heartbeat OGC ® © 2011 Open Geospatial Consortium, Inc. 1 6
SAA Pilot Scenarios 1. Commercial Flight (Lufthansa Systems & Luciad) – Flight planning • Dispatch personnel plans a flight from KORD to KLAX by generating route from departure to destination and checking restrictions along the route (checking for airspaces that are active at the time the aircraft would pass them) • Optimized route is released as part of electronic briefing package to crew – Flight preparation • Crew loads briefing package and visually inspect the route on their enroute chart (and checking all SUAs and their activation times) • Subscription for hearbeat reservation updates is registered with the Event Service – Flight conduction • During the flight, a new reservation for a restricted area is published. The event is received on flight deck. The crew checks the new activation time and location of the airspace and determine that the flight route does not cross the airspace directly • When passing by the active airspace one hour later, the crew checks again to make sure to avoid the airspace – In-flight replanning • Severe weather is encountered and the flight has to be diverted. • To plan diversion route, the crew displays the enroute chart including all SAAs represented differently (by color/pattern) depending on their activation time (active, becomes actives in 2/4/8 hours). The crew plans a new route. ® OGC © 2011 Open Geospatial Consortium, Inc. 1 7
SAA Pilot Scenarios 2. VFR GPS Chart Production (Jeppesen) – Interaction between a client production data maintenance application and the FAA SAA services for the ingestion of AIXM SAA data for use in client end product • Initial population of client data store with both Baseline SAA static data information and Baseline SAA Schedule data information • Subscription to Event Service for notification of any changes as they occur • Processing of SAA Static Delta changes and SAA Schedule Delta changes • Client production process ingests AIXM data, validates it is compliant with the published AIXM version and converts AIXM into appropriate formats for client end product. • Final output is graphical display of SAA static and schedule data 3. Student Pilot – Student pilot is planning a cross-country circuit to receive her solo license certification. • A round-trip route with both touch-and-go and airport sign-in stops will include five airports. During a sign-in stop, the pilot uses her mobile device to receive a commercial service notification of the cancellation of a nearby military mission that will allow a more direct route to the next airport, and the flight is re-planned and re-filed with the ARTC.

SAA Pilot Scenarios 4. Logistics Supply Mission – An Air Mobility Command pilot at Eglin AFB is notified that some equipment is needed immediately at Mc. Guire AFB. The local Air Base ops are closed. • The pilot uses the Internet to identify airspace scheduled by Mc. Guire that involve altitudes below 10000 feet MSL, and to obtain SAA reservation schedules for these airspace that will be active within the next 24 hours. He obtains flight plan approval from the local ARTC, and his departure is scheduled for three hours in the future. • Just before boarding the airplane, the pilot receives notification of a new SAA activation that impacts his flight plan. These pre-flight changes are seen as highlighted modifications on a display showing both his original flight plan and the new route. 5. Land Management Survey – The Bureau of Land Management is conducting an aerial survey to count the deer population within a 50, 000 square foot area defined as a rectangular polygon. Parts of this area are adjacent to an Air Force field used for target practice that requires NOTAM notifications for activation. • The survey is underway when a 2 -hour advance notice of activation is communicated to the local ARTC, which subscribes to such notifications for SAA within 100 nm of their facility. The ARTC warns the pilot of the planned activation. OGC ® 6. Styling and Portrayal Scenario(s) © 2011 Open Geospatial Consortium, Inc. 1 9
