Narrative:

Cleared for ILS ZZZ. Atl approach cleared flight to descend to 3500 ft until established cleared for approach ZZZ. Missed approach altitude was set prior to capturing 3500 ft. Descent continued to 3000 ft in VMC conditions. Charted altitude that segment 2700 ft. Glideslope not captured. Stop descent at 3000 ft; continued approach at that altitude until glideslope intercepted occurred and continued approach normally without further. Earlier in the day there had been an altercation between crew members that was initiated by the first officer. On an earlier approach into ZZZ; the first officer was struggling to get the aircraft stabilized on an approach to runway; 30 KTS fast on the approach and not responding to my input in a timely fashion. The most expedient method to comply with ATC instructions was for me to physically take control of the aircraft. This infuriated the first officer. He let me know this after we parked the aircraft at the gate. He stated he could have completed the approach just fine. My perspective of the situation significantly differed from his perspective. Much was said and a resolution was attempted. However; in hindsight; adequate resolution was not achieved. The first officer by his own admission confided to me that he needed my help; but appeared angered when help or suggestions or even when a question was posed to him about operational considerations. I believe this ultimately continued to be a distraction and full attention to detail was; therefore; compromised.

Title: CRJ700 FLIGHT CREW DESCENDS BELOW THEIR CLEARANCE ALTITUDE BEFORE ILS GLIDE SLOPE CAPTURE ON AN ILS APPROACH.

Narrative: CLRED FOR ILS ZZZ. ATL APCH CLRED FLT TO DSND TO 3500 FT UNTIL ESTABLISHED CLRED FOR APCH ZZZ. MISSED APCH ALT WAS SET PRIOR TO CAPTURING 3500 FT. DSCNT CONTINUED TO 3000 FT IN VMC CONDITIONS. CHARTED ALT THAT SEGMENT 2700 FT. GLIDESLOPE NOT CAPTURED. STOP DSCNT AT 3000 FT; CONTINUED APCH AT THAT ALT UNTIL GLIDESLOPE INTERCEPTED OCCURRED AND CONTINUED APCH NORMALLY WITHOUT FURTHER. EARLIER IN THE DAY THERE HAD BEEN AN ALTERCATION BTWN CREW MEMBERS THAT WAS INITIATED BY THE FO. ON AN EARLIER APCH INTO ZZZ; THE FO WAS STRUGGLING TO GET THE ACFT STABILIZED ON AN APCH TO RWY; 30 KTS FAST ON THE APCH AND NOT RESPONDING TO MY INPUT IN A TIMELY FASHION. THE MOST EXPEDIENT METHOD TO COMPLY WITH ATC INSTRUCTIONS WAS FOR ME TO PHYSICALLY TAKE CTL OF THE ACFT. THIS INFURIATED THE FO. HE LET ME KNOW THIS AFTER WE PARKED THE ACFT AT THE GATE. HE STATED HE COULD HAVE COMPLETED THE APCH JUST FINE. MY PERSPECTIVE OF THE SITUATION SIGNIFICANTLY DIFFERED FROM HIS PERSPECTIVE. MUCH WAS SAID AND A RESOLUTION WAS ATTEMPTED. HOWEVER; IN HINDSIGHT; ADEQUATE RESOLUTION WAS NOT ACHIEVED. THE FO BY HIS OWN ADMISSION CONFIDED TO ME THAT HE NEEDED MY HELP; BUT APPEARED ANGERED WHEN HELP OR SUGGESTIONS OR EVEN WHEN A QUESTION WAS POSED TO HIM ABOUT OPERATIONAL CONSIDERATIONS. I BELIEVE THIS ULTIMATELY CONTINUED TO BE A DISTR AND FULL ATTN TO DETAIL WAS; THEREFORE; COMPROMISED.
