Narrative:

For the second time in a couple of weeks; when I have been cleared for the ILS 12 at bzn; salt lake ATC has been holding me very high; much higher than the MDA on the respective transitions; and only 'clearing' me for the approach (i.e. Allowing me to descend to the MDA) after turning inbound on the localizer. Problem is; they have kept me at 12000 ft MSL until that point; and the MDA at that part of the approach is 6800 ft. Salt lake did this to me once while flying the 14 mile DME arc from the north; and yesterday while on the hia transition. It is completely impossible to have a stabilized approach under those circumstances. I understand that ZLC loses radar coverage below 12000 ft here; but as long as I am established on a transition; why are they holding me high? This is a safety issue for me; as I am finding it almost impossible to intercept the glideslope prior to manni; the FAF.callback conversation with reporter revealed the following information: reporter stated the performance limitations of his aircraft make it very difficult to execute a safe; stabilized approach with salt lake center keeping him that high on the approach. When he requests lower altitude earlier in the procedure; center denies the request.

Title: A BE30 PLT RPTS ZLC KEEPS HIM TOO HIGH ON APCH TO BZN TO ALLOW A STABILIZED APCH.

Narrative: FOR THE SECOND TIME IN A COUPLE OF WEEKS; WHEN I HAVE BEEN CLEARED FOR THE ILS 12 AT BZN; SALT LAKE ATC HAS BEEN HOLDING ME VERY HIGH; MUCH HIGHER THAN THE MDA ON THE RESPECTIVE TRANSITIONS; AND ONLY 'CLEARING' ME FOR THE APPROACH (I.E. ALLOWING ME TO DESCEND TO THE MDA) AFTER TURNING INBOUND ON THE LOCALIZER. PROBLEM IS; THEY HAVE KEPT ME AT 12000 FT MSL UNTIL THAT POINT; AND THE MDA AT THAT PART OF THE APPROACH IS 6800 FT. SALT LAKE DID THIS TO ME ONCE WHILE FLYING THE 14 MILE DME ARC FROM THE NORTH; AND YESTERDAY WHILE ON THE HIA TRANSITION. IT IS COMPLETELY IMPOSSIBLE TO HAVE A STABILIZED APPROACH UNDER THOSE CIRCUMSTANCES. I UNDERSTAND THAT ZLC LOSES RADAR COVERAGE BELOW 12000 FT HERE; BUT AS LONG AS I AM ESTABLISHED ON A TRANSITION; WHY ARE THEY HOLDING ME HIGH? THIS IS A SAFETY ISSUE FOR ME; AS I AM FINDING IT ALMOST IMPOSSIBLE TO INTERCEPT THE GLIDESLOPE PRIOR TO MANNI; THE FAF.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THE PERFORMANCE LIMITATIONS OF HIS ACFT MAKE IT VERY DIFFICULT TO EXECUTE A SAFE; STABILIZED APCH WITH SALT LAKE CTR KEEPING HIM THAT HIGH ON THE APCH. WHEN HE REQUESTS LOWER ALT EARLIER IN THE PROC; CTR DENIES THE REQUEST.
