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.

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.

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.

Aircraft capable of using the NRS should include HARHAR or PTPPTP in remarks.
– HARHAR indicates ability to use all of the NRS.
– PTPPTP 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.

• 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.
