Narrative:

The flight was conducted using the 'life guard,' designation. The forecast WX for the applicable time frame of operation at slc indicated visibility on the order of 1/2-1/4 mi in fog. Prior to departing ege airport en route to slc I made checks of WX trends, current surface analysis and forecasts for the slc area. The updates indicated that the RVR at slc was fluctuating between 1800 ft and 3500 ft and holding at those values with en route WX being clear. En route and approximately 30 mins out from ege I was advised by the medical team in the aircraft that the patient was in a time critical condition and that an undelayed arrival into slc was urgently needed. I advised salt lake city ARTCC of patient status and requested that center call slc tower for an advisory on salt lake city airport #2 for the purpose of contingency planning. Center reported that #2 was open but the fog rolled in covering the airport by the time we were in the vicinity. Upon being vectored for the ILS 34L approach the reported RVR was at 800 ft/800 ft/600 ft. I advised ATC that would need to 'take a look' at the approach with the following factors in mind: 1) FARS provide for deviations from mins to meet emergency requirements. 2) the ILS 34L approach is certified for CAT III operation and was fully functional, to include attendant lighting and markings. 3) I was confident in my ability to safely conduct the approach. 4) I was fully prepared to make a missed approach regardless of any medical problem if adequate forward visibility for landing and rollout was not available. 5) the aircraft was equipped with a fully functioning flight director system and a radar altimeter. 6) I have well in excess of 100 hours PIC time in type. The approach and landing were accomplished without incident or problem. Callback conversation with reporter revealed the following information: reporter states he felt he could successfully complete flight when departed. As WX deteriorated he felt only option was to attempt approach and do a missed if necessary. Patient condition was very much a factor.

Title: EMS FLT MAKES APCH AND LNDG BELOW MINS.

Narrative: THE FLT WAS CONDUCTED USING THE 'LIFE GUARD,' DESIGNATION. THE FORECAST WX FOR THE APPLICABLE TIME FRAME OF OP AT SLC INDICATED VISIBILITY ON THE ORDER OF 1/2-1/4 MI IN FOG. PRIOR TO DEPARTING EGE ARPT ENRTE TO SLC I MADE CHKS OF WX TRENDS, CURRENT SURFACE ANALYSIS AND FORECASTS FOR THE SLC AREA. THE UPDATES INDICATED THAT THE RVR AT SLC WAS FLUCTUATING BTWN 1800 FT AND 3500 FT AND HOLDING AT THOSE VALUES WITH ENRTE WX BEING CLR. ENRTE AND APPROX 30 MINS OUT FROM EGE I WAS ADVISED BY THE MEDICAL TEAM IN THE ACFT THAT THE PATIENT WAS IN A TIME CRITICAL CONDITION AND THAT AN UNDELAYED ARR INTO SLC WAS URGENTLY NEEDED. I ADVISED SALT LAKE CITY ARTCC OF PATIENT STATUS AND REQUESTED THAT CTR CALL SLC TWR FOR AN ADVISORY ON SALT LAKE CITY ARPT #2 FOR THE PURPOSE OF CONTINGENCY PLANNING. CTR RPTED THAT #2 WAS OPEN BUT THE FOG ROLLED IN COVERING THE ARPT BY THE TIME WE WERE IN THE VICINITY. UPON BEING VECTORED FOR THE ILS 34L APCH THE RPTED RVR WAS AT 800 FT/800 FT/600 FT. I ADVISED ATC THAT WOULD NEED TO 'TAKE A LOOK' AT THE APCH WITH THE FOLLOWING FACTORS IN MIND: 1) FARS PROVIDE FOR DEVS FROM MINS TO MEET EMER REQUIREMENTS. 2) THE ILS 34L APCH IS CERTIFIED FOR CAT III OP AND WAS FULLY FUNCTIONAL, TO INCLUDE ATTENDANT LIGHTING AND MARKINGS. 3) I WAS CONFIDENT IN MY ABILITY TO SAFELY CONDUCT THE APCH. 4) I WAS FULLY PREPARED TO MAKE A MISSED APCH REGARDLESS OF ANY MEDICAL PROBLEM IF ADEQUATE FORWARD VISIBILITY FOR LNDG AND ROLLOUT WAS NOT AVAILABLE. 5) THE ACFT WAS EQUIPPED WITH A FULLY FUNCTIONING FLT DIRECTOR SYS AND A RADAR ALTIMETER. 6) I HAVE WELL IN EXCESS OF 100 HRS PIC TIME IN TYPE. THE APCH AND LNDG WERE ACCOMPLISHED WITHOUT INCIDENT OR PROBLEM. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES HE FELT HE COULD SUCCESSFULLY COMPLETE FLT WHEN DEPARTED. AS WX DETERIORATED HE FELT ONLY OPTION WAS TO ATTEMPT APCH AND DO A MISSED IF NECESSARY. PATIENT CONDITION WAS VERY MUCH A FACTOR.
