Narrative:

I was the instrument on an instrument training flight in small aircraft preparing to make an ILS 3 approach at gsp. We were told to intercept the localizer and maintain 2700' and that we had traffic at 6 O'clock, 4300', an medium large transport that would be passing over us. After it passed over us we reported it in sight. At the time of sighting the jet we were about 1 mi outside of the OM which means the medium large transport was close or at the marker. At this time the jet was cleared to land and we were cleared for the approach. This meant the jet had to descend through our approach path in a landing confign. This caused a considerable amount of wake turbulence for us west/O our having time to request a clearance to deviate out of the turbulence. This seems unsafe also because the jet could not have us in sight at the time of descending to land.

Title: CLEARED FOR APCH DIRECTLY INTO WAKE TURBULENCE.

Narrative: I WAS THE INSTR ON AN INSTRUMENT TRNING FLT IN SMA PREPARING TO MAKE AN ILS 3 APCH AT GSP. WE WERE TOLD TO INTERCEPT THE LOC AND MAINTAIN 2700' AND THAT WE HAD TFC AT 6 O'CLOCK, 4300', AN MLG THAT WOULD BE PASSING OVER US. AFTER IT PASSED OVER US WE RPTED IT IN SIGHT. AT THE TIME OF SIGHTING THE JET WE WERE ABOUT 1 MI OUTSIDE OF THE OM WHICH MEANS THE MLG WAS CLOSE OR AT THE MARKER. AT THIS TIME THE JET WAS CLRED TO LAND AND WE WERE CLRED FOR THE APCH. THIS MEANT THE JET HAD TO DSND THROUGH OUR APCH PATH IN A LNDG CONFIGN. THIS CAUSED A CONSIDERABLE AMOUNT OF WAKE TURB FOR US W/O OUR HAVING TIME TO REQUEST A CLRNC TO DEVIATE OUT OF THE TURB. THIS SEEMS UNSAFE ALSO BECAUSE THE JET COULD NOT HAVE US IN SIGHT AT THE TIME OF DSNDING TO LAND.
