Human Factors
When setting up for visual backed up by the ILS XX into ZZZ we couldn't get the LOC/GS identified and decided to break off and back up our visual using the RNAV XX. Once set up we came back around and upon crossing ZZZZZ I mistakenly set 2600 ft. instead of the DDA; I didn't realize ZZZZZ was the final approach fix and continued to 'dive and drive' with a 1500fpm descent rate; at 2600 ft. we received a low altitude alert from ATC and realized my mistake and that I was 20 ft. below the required altitude of 2620 ft. at ZZZZZ1. I immediately initiated a go around where we came back in uneventfully. Did not set DDA at FAF and initiated a descent well beyond the proper 700fpm descent rate resulting in getting low.
Upon vectors for the ILS we noticed no blue/ghost needles. We selected the nav source to the ILS frequency; still no ghost needles. I recalled the NOTAM for the ILS being out but it was only for XA00-XG00 local. We inquired with approach they said it was working. We elected to be pulled off the approach and set up for the RNAV. When coming in for the RNAV we thought we were brought out much further beyond the FAF. We began to descend with 2600 ft. set the next fix was 2620. We got an altitude alert and elected to go around at 2600 ft. as soon as we knew we were low by 20 ft. We [had] both mistaken the FAF. we realized we were beyond the FAF after the go around. We then came back and did the ILS by turning the course knob and listening to the nav frequency to identify it. Being rushed on a short flight and being rushed to set up for an RNAV during a line check had us misidentify the FAF for the RNAV approach.
CRJ-700 flight crew reported a CFTT event when they set up the approach using the wrong Final Approach Fix and descended below a required crossing altitude. ATC alerted the crew who conducted a go around to a landing.
