2. Navigation Reference System • Initial Implementation: • June 10, 2004 • ZAU, ZKC, ZMP, ZDV, ZLC, ZOA, ZSE • National Implementation: • May 12, 2005 • Remaining Centers (48 contiguous states) • Non-Oceanic and Domestic Airspace Only • Anchorage Center TBD F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

3. Navigation Reference System NRS Waypoints may be used: • As part of a filed flight plan • For route changes requested by flight crews • Tactically by controllers NRS Waypoints are currently not intended to be included as part of TMU initiated routes.

4. Navigation Reference System Expect a more immediate use by GA and corporate aircraft, with a gradual increase of usage by Airlines. Aircraft database memory limitations will restrict user ability to fly the NRS. Some aircraft have less that 128K of onboard memory !!!!

5. Navigation Reference System Customers seek to file flight plans based on their own operational priorities. • To the maximum extent possible, these aircraft should be left on the filed route. • Filing via NRS and/or NRR (the Non-Restrictive Routing portion of High Altitude Redesign) gives users freedom to develop a flight path that meets all goals. F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

6. Navigation Reference System Aircraft capable of using the NRS should include HAR or PTP in remarks. • HAR indicates ability to use all of the NRS. • PTP indicates Limited or No NRS capability. Controllers should be aware this is not a mandatory filing standard. System Users have been asked for voluntary compliance. It is possible controllers may find conflicting information. Issues? Notify your NAR FLT so the HAR office can address the problem. F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

7. What Is the Designator to Identify Which Aircraft Are Participating in HAR? HARin field 11 of the flight plan identifies aircraft that have the capability of participating in these functionalities of HAR: • NRS Waypoint • Waypoints around SUA’s and ATCAA’s • Pitch / Catch points (Non-Restrictive Routing) F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

8. What Is the Designator to Identify Which Aircraft Are Participating in HAR? PTPin field 11 of the flight plan identifies aircraft that have the capability of participating in LIMITED functions of HAR: • Limited or No NRS Waypoints • Possible Limitations on • Waypoints around SUA’s and ATCAA’s • Pitch / Catch points (Non-Restrictive Routing) F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

9. Fly By vs Fly Over Waypoints • All Enroute NRS waypoints are FLY BY unless being used for: • holding aircraft • associated with a published SID or STAR • All controllers should be aware of possible early turn or late turn characteristics associated with high altitude turns.
