Narrative:
Approach was normal. On vector to final, ILS 29R given heading 270, 3 mi from bonna, maintain 4000 to bonna, 170 to jacko, cleared ILS 29R, tower at jacko. As we turned the localizer became active, but at 4000 ft the GS was full scale down. Since the ILS 29R has no DME, this was in conflict with ATC call of outside bonna, where the GS should be above. We checked idents again (both good) then switched to msp VOR for DME. It was 7.1 leaving us well inside bonna. We had to use excessive descent rates and speed to get down, which put us too close to traffic ahead of us, forcing a missed approach (which always scares the bejesus out of the passenger)! I believe the final turn put us well inside bonna, not 3 mi from. That, plus no DME on the ILS forced us to maintain 4000 ft until we were sure of our position, resulting in a lousy approach, and forced missed approach.

Title: ACR MLG FORCED INTO A GAR FROM A NON STABILIZED APCH INTO MSP.
Narrative: APCH WAS NORMAL. ON VECTOR TO FINAL, ILS 29R GIVEN HDG 270, 3 MI FROM BONNA, MAINTAIN 4000 TO BONNA, 170 TO JACKO, CLRED ILS 29R, TWR AT JACKO. AS WE TURNED THE LOC BECAME ACTIVE, BUT AT 4000 FT THE GS WAS FULL SCALE DOWN. SINCE THE ILS 29R HAS NO DME, THIS WAS IN CONFLICT WITH ATC CALL OF OUTSIDE BONNA, WHERE THE GS SHOULD BE ABOVE. WE CHKED IDENTS AGAIN (BOTH GOOD) THEN SWITCHED TO MSP VOR FOR DME. IT WAS 7.1 LEAVING US WELL INSIDE BONNA. WE HAD TO USE EXCESSIVE DSCNT RATES AND SPD TO GET DOWN, WHICH PUT US TOO CLOSE TO TFC AHEAD OF US, FORCING A MISSED APCH (WHICH ALWAYS SCARES THE BEJESUS OUT OF THE PAX)! I BELIEVE THE FINAL TURN PUT US WELL INSIDE BONNA, NOT 3 MI FROM. THAT, PLUS NO DME ON THE ILS FORCED US TO MAINTAIN 4000 FT UNTIL WE WERE SURE OF OUR POS, RESULTING IN A LOUSY APCH, AND FORCED MISSED APCH.
