Narrative:
Aircraft was on localizer only approach at atl. Copilot descended early on approach and went below vectoring altitude. Tower's low altitude alert went off. Tower initiated a go around to another uneventful landing. Cause: copilot correctly briefed descent point but captain questioned the copilot if he should not descend at tizzy (4 mi short), copilot agreed. Factors: long duty day, 13+ hours. Fatigue due to last leg being in moderate turbulence for 2 hours. Numerous holds and a reroute, short layover scheduled (at 8 hours 6 mins), late night. Fixes: both pilots be more cognizant of the approach and brief an unusual approach more forcefully.
Original NASA ASRS Text
Title: FLC OF AN MD88 WAS GIVEN A GAR BY TWR WHEN THE TWR LOW ALT ALERTER SOUNDED DURING AN ILS APCH IN IMC WX CONDITIONS. FLC HAD MADE AN ERROR WHEN BRIEFING THE APCH DSCNT POINT FIX.
Narrative: ACFT WAS ON LOC ONLY APCH AT ATL. COPLT DSNDED EARLY ON APCH AND WENT BELOW VECTORING ALT. TWR'S LOW ALT ALERT WENT OFF. TWR INITIATED A GAR TO ANOTHER UNEVENTFUL LNDG. CAUSE: COPLT CORRECTLY BRIEFED DSCNT POINT BUT CAPT QUESTIONED THE COPLT IF HE SHOULD NOT DSND AT TIZZY (4 MI SHORT), COPLT AGREED. FACTORS: LONG DUTY DAY, 13+ HRS. FATIGUE DUE TO LAST LEG BEING IN MODERATE TURB FOR 2 HRS. NUMEROUS HOLDS AND A REROUTE, SHORT LAYOVER SCHEDULED (AT 8 HRS 6 MINS), LATE NIGHT. FIXES: BOTH PLTS BE MORE COGNIZANT OF THE APCH AND BRIEF AN UNUSUAL APCH MORE FORCEFULLY.
