Narrative:

My second IFR since passing the rating at the end of november. I've been maintaining currency on the simulator, but was 1) rusty using 'the system' and 2) flying the same approachs. Today was perfect for dipping my toe in. Cavok at departure, scattered en route, overcast at destination with relatively high ceiling. I elected to take the C182RG to practice landing/flying the approach in a complex (less than 10% of my total time is complex). Almost all of my instrument training flts were in the C172. En route along a victor airway, with a transition from IAF (intersection) flying (heading) to intercept the localizer. The transition was at 3200 ft. After localizer intercept, continued at 3200 ft to intersection DME from ILS, then descend to 1800 ft for GS intercept. I missed that part and flew the localizer at 3200 ft until GS intercept. At GS intercept, I called CTAF and reported my position (distance) from the runway at the OM. I realized my error shortly after that when the OM beacon went off. No harm was done, but I realize that even an airport I am familiar with VFR may have gotchas in the instrument procedures. It was a good lesson.

Title: A LOW TIME C182RG PVT PLT FAILS TO FOLLOW THE PROFILE FOR THE ILS APCH AT HQM, WA.

Narrative: MY SECOND IFR SINCE PASSING THE RATING AT THE END OF NOVEMBER. I'VE BEEN MAINTAINING CURRENCY ON THE SIMULATOR, BUT WAS 1) RUSTY USING 'THE SYS' AND 2) FLYING THE SAME APCHS. TODAY WAS PERFECT FOR DIPPING MY TOE IN. CAVOK AT DEP, SCATTERED ENRTE, OVCST AT DEST WITH RELATIVELY HIGH CEILING. I ELECTED TO TAKE THE C182RG TO PRACTICE LNDG/FLYING THE APCH IN A COMPLEX (LESS THAN 10% OF MY TOTAL TIME IS COMPLEX). ALMOST ALL OF MY INST TRAINING FLTS WERE IN THE C172. ENRTE ALONG A VICTOR AIRWAY, WITH A TRANSITION FROM IAF (INTXN) FLYING (HDG) TO INTERCEPT THE LOC. THE TRANSITION WAS AT 3200 FT. AFTER LOC INTERCEPT, CONTINUED AT 3200 FT TO INTXN DME FROM ILS, THEN DSND TO 1800 FT FOR GS INTERCEPT. I MISSED THAT PART AND FLEW THE LOC AT 3200 FT UNTIL GS INTERCEPT. AT GS INTERCEPT, I CALLED CTAF AND RPTED MY POS (DISTANCE) FROM THE RWY AT THE OM. I REALIZED MY ERROR SHORTLY AFTER THAT WHEN THE OM BEACON WENT OFF. NO HARM WAS DONE, BUT I REALIZE THAT EVEN AN ARPT I AM FAMILIAR WITH VFR MAY HAVE GOTCHAS IN THE INST PROCS. IT WAS A GOOD LESSON.
