FAR 61.57 states that to act as PIC under IFR or weather conditions lower than the minimums prescribed for VFR, you must have performed & logged, within the previous 6 calendar months prior to the month of the flight, 6 approaches, holding procedures & tasks, and intercepting & tracking courses in actual or simulated conditions.
If you failed to meet these requirements, you have 6 more months to log them under simulated conditions or in a training device/simulator.
After those additional 6 calendar months, you must get an Instrument Proficiency Check to re-establish IFR currency.
I understand all of the above.
My question is, where or how does the regulation say, that you are IFR current for those first 6 calendar months once you establish currency with an IPC, or the instrument checkride?
