Narrative:
We accepted a visual approach to slc runway 34L in VFR conditions from slc approach control. The turn on was 'high and tight.' we elected to execute a missed approach at approximately 1100 ft AGL and requested a 'left closed VFR pattern' from tower. Tower immediately granted the request. At approximately 2 mi south on downwind at 1500 ft AGL, the tower directed we turn inbound. We declined as it would have resulted in non-stable approach at 1000 ft AGL. We continued to approximately 3 1/2 to 4 mi, turned inbound and landed uneventfully. In a subsequent cordial discussion with the tower supervisor, it turns out there are VFR corridors 3 mi north and south of the airport at 6000 ft MSL (approximately 1500 ft above field elevation) and we had encroached in the southern corridor. I explained to him that we did not have any way of knowing those corridors exist as they are not shown on the airport page as they are at other airports such as lax. Also, we discussed the requirement to be stable at 1000 ft AGL on final.

Title: A FLT CREW ENCROACHED ON A VFR CORRIDOR AT SLC ARPT DUE TO NEEDING TO EXTEND DOWNWIND TO STABILIZE THE ACFT.
Narrative: WE ACCEPTED A VISUAL APCH TO SLC RWY 34L IN VFR CONDITIONS FROM SLC APCH CTL. THE TURN ON WAS 'HIGH AND TIGHT.' WE ELECTED TO EXECUTE A MISSED APCH AT APPROX 1100 FT AGL AND REQUESTED A 'L CLOSED VFR PATTERN' FROM TWR. TWR IMMEDIATELY GRANTED THE REQUEST. AT APPROX 2 MI S ON DOWNWIND AT 1500 FT AGL, THE TWR DIRECTED WE TURN INBOUND. WE DECLINED AS IT WOULD HAVE RESULTED IN NON-STABLE APCH AT 1000 FT AGL. WE CONTINUED TO APPROX 3 1/2 TO 4 MI, TURNED INBOUND AND LANDED UNEVENTFULLY. IN A SUBSEQUENT CORDIAL DISCUSSION WITH THE TWR SUPVR, IT TURNS OUT THERE ARE VFR CORRIDORS 3 MI N AND S OF THE ARPT AT 6000 FT MSL (APPROX 1500 FT ABOVE FIELD ELEVATION) AND WE HAD ENCROACHED IN THE SOUTHERN CORRIDOR. I EXPLAINED TO HIM THAT WE DID NOT HAVE ANY WAY OF KNOWING THOSE CORRIDORS EXIST AS THEY ARE NOT SHOWN ON THE ARPT PAGE AS THEY ARE AT OTHER ARPTS SUCH AS LAX. ALSO, WE DISCUSSED THE REQUIREMENT TO BE STABLE AT 1000 FT AGL ON FINAL.
