Estonia follows instrument flight rules established by the European Commission Implementing Regulation (EU) No 923/2012.
Free Route Airspace (FRA):
A specified airspace within which users may freely plan a route between a defined entry point and a defined exit point, with the possibility to route via intermediate (published or unpublished) way points, without reference to the ATS route network, subject to airspace availability. Within this airspace, flights remain subject to air traffic control.
FRA Arrival Connecting Point (A):
A FRA (A) point is a published significant point (5LNC or NAVAID) to which FRA operations are allowed for arriving traffic to specific aerodromes.
FRA Departure Connecting Point (D):
A FRA (D) point is a published significant point (5LNC or NAVAID) from which FRA operations are allowed for departing traffic from specific aerodromes.
FRA Horizontal Entry Point (E):
A FRA (E) point is a published significant point (5LNC or NAVAID) on the horizontal boundary of the Free Route Airspace from which FRA operations are allowed.
FRA Horizontal Exit Point (X):
A FRA (X) point is a published significant point (5LNC or NAVAID) on the horizontal boundary of the Free Route Airspace to which FRA operations are allowed.
Combined FRA Arrival Connecting and FRA Departure Connecting Point (AD):
A FRA (AD) point is a published significant point (5LNC or NAVAID) to/from which FRA operations are allowed for arriving/departing traffic to/from specific aerodromes.
Combined FRA Horizontal Entry and FRA Horizontal Exit Point (EX):
A FRA (EX) point is a published significant point (5LNC or NAVAID) on the horizontal boundary of the Free Route Airspace from which and to which FRA operations are allowed.
FRA Intermediate Point (I):
A FRA (I) point is a published significant point (5LNC or NAVAID) or unpublished point, defined by geographical coordinates or by bearing and distance via which FRA operations are allowed.
Eligible flights are all flights that are intending to operate within the vertical and horizontal limits of NEFAB FRA and/or in DK/SE FAB FRA as specified in ENR 2.2 in the national AIPs. This includes arriving, departing and transiting traffic.
Eligible flights shall flight plan according to the table below.
From | To | Remark |
|---|---|---|
FRA Entry Point | FRA Exit Point | Flight plan DCT or via one or several FRA intermediate points. FRA intermediate point can either be a navaid (as published in ENR 4.1) or a significant point (as published in ENR 4.4) in the national AIP of Estonia, Finland, Latvia, Norway, Sweden or Denmark. FRA intermediate points can also be entered as coordinates. |

Access to FRA for departing traffic is via a FRA Departure Connecting Point.
Depending on the aerodrome there are different requirements:
a SID Final Waypoint,
a specific connecting point linked to an aerodrome according to the RAD, Appendix 5,
if required, the last point on a FRA Connecting Route as described in ENR 3.5,
if no suitable SID is available or there is no requirement for a connecting point, a waypoint within a required distance from the aerodrome according to the RAD, Appendix 5.
Exiting FRA for arriving traffic is via a FRA Arrival Connecting Point.
Depending on the aerodrome there are different requirements:
a STAR Initial Waypoint,
a specific connecting point linked to an aerodrome according to the RAD, Appendix 5,
if required, the first point on a FRA Connecting Route as described in ENR 3.5,
if no suitable STAR is available or there is no requirement for a connecting point, a waypoint within a required distance from the aerodrome according to the RAD, Appendix 5.
Requirements for IFR flights related to VHF 8.33 kHz channel spacing radio equipage are stated in GEN 1.5.
