GCRPt in generated flight plan

Recommended Posts

Hello All; 

Quick Question:

What are these GCRPt_0, GTRPt_1, etc. points that are being generated in the Auto Plan flight plan?
Will the effect my flight plan in the plane?

For instance: KDCA to KSFO is entered then Auto Plan is pressed. Then you get all these crazy GCRPt_x waypoints. 

Just curious.

GCRPts are "Great Circle Route Pts" and are added when the distance between waypoints is over about 250 NMs.  Generally, this is an indication that you need to add airways or other waypoints to have a good flight plan.

When you add the airways or other waypoints, the GCRPts will be removed.

Depending on the aircraft and its avionics, the GCRPts may cause an issue with the GPS/Autopilot function, so replacing them is always a good idea.
