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.

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.

7. What Is the Designator to Identify Which Aircraft Are Participating in HAR?
HAR in 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)

PTP in field 11 of the flight plan identifies aircraft that have the capability of participating in LIMITED functions of HAR:
Limited or No NRS Waypoints

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.

You can check out our progress and view some of our performance measures at
With the establishment of the ATO, we’re creating room for the professionals in the FAA to exercise their judgment and apply their knowledge to achieve goals that are explicitly stated and clearly measured.
We’re creating a government organization that honors performance above process, cost-awareness above fiscal indifference, innovation above rigidity, and transparency above the self-protective cover of sometimes arcane rules and regulations.
I’m delighted to be part of such an exciting and rewarding adventure.
