Sondrestrom APP

Sondrestrom Approach (BGSF_APP) provides an approach control service within the Sondrestrom TMA and CTA.

Sondrestrom TMA & CTA

The Sondrestrom TMA and CTA together make up the airspace controlled by Sondrestrom Approach.

The CTA and TMA are arranged as three sections of cylindrical airspace.

Arrivals

There are no STARs into BGSF. Aircraft generally join the instrument approach procedures directly from their flight plan route.

Runway 09

The RNP approach for RWY 09 is the preferred approach type. Aircraft should be cleared to either of the IAFs (DODIP or BELZI) and descended to the initial approach altitudes as published:

Missed Approach

TWR shall instruct aircraft to follow the standard missed approach. The standard missed approach varies between approaches:

Strict adherence to the standard missed approaches is critical due to high terrain surrounding the airport.

TWR shall instruct aircraft unable the standard missed approach to perform a visual climb.

TWR shall coordinate all missed approaches with APP prior to transferring back to APP.

Non-Standard Approaches (RWY 09)

If aircraft are unable to accept the RNP approach, then alternative approaches should be offered in order of precision.

LOC Z/Y

There are two published localizer approaches – LOC Z (for category A and B aircraft) and LOC Y (for category C and D aircraft.) They are both teardrop procedures, starting from SF NDB and making a left turn inbound for the localizer.

As both procedures descend into the BGSF CTR, APP should coordinate with TWR to make them aware if the approaches are used.

NDB Z/Y

There are, similarly two NDB approaches – NDB Z (for category A and B) and NDB Y (for category C and D.) They are also teardrop procedures, except instead of using the localizer, aircraft fly a final approach course towards SF NDB and the runway.

As both procedures descend into the BGSF CTR, APP should coordinate with TWR to make them aware if the approaches are used.

Runway 27

While not officially published for RWY 27, there are two RNP approaches available which lead aircraft to RWY 27. (RNP A for categories A and B, and RNP B for categories C and D.)

Aircraft should be cleared to one of the three IAFs (RUMAQ, FICWE, or KEFOP)  and descended to the initial approach altitudes as published:

Alternatively, aircraft may perform a visual approach.

Circle-to-land is not permitted north of the aerodrome.

Departures

Aircraft shall follow either their SID, or the non-RNAV RWY 27 departure procedure of climbing on runway track, then when passing 5300ft, proceeding direct to join their flight planned route.

Strict adherence to the SID is required below the MSA (5300ft) due to high terrain. After passing the MSA, APP may issue a direct to the end of the SID, traffic permitting.
