• A published NAVAID/Significant Point from which FRA operations are allowed.

FRA Exit Point (X):

• published NAVAID/Significant Point to which FRA operations are allowed.

FRA Intermediate Point (I):

• A published NAVAID/Significant Point or unpublished point, defined by geographical coordinates or by a bearing and distance via which FRA operations are allowed for all traffic.

FRA Connecting Route:

• One or more segment(s) connecting a SID end point (or other departure procedure) with a FRA Departure Connecting Point, or FRA Arrival Connecting point with a STAR start point (or other arrival procedure).
