A321
Confusion; Fatigue; Situational Awareness
Deviation / Discrepancy - Procedural Published Material / Policy; Inflight Event / Encounter Unstabilized Approach
Human Factors
This is a fatigue related event that led to a momentary unstable approach configuration on final. This was the sixth day in a row of reserve flying for me. Well over 30 hours of flight/deadhead time in preceding six days.Layover preceding night in LAS. I awoke throughout night by noise next door and above me. This hotel is unusually noisy due to thin walls and loud plumbing. Doors slamming; coughing; flushing toilets interrupted sleep thru the night.Felt somewhat rested next morning at sign in; heavy workload to depart LAS due to weight restrictions and fuel requirements. Numerous altitude changes and deviations due to ride and weather enroute. Fuel upon landing becoming an issue. I felt fatigued prior to descent; saying that it's been a long week and the hotel was inadequate. On final approach; copilot asked me to set missed approach; I did and then inadvertently pushed button which took us out of approach mode and into climb mode. Copilot quickly disengaged auto throttles and AP and hand flew approach. I contribute this 100% to fatigue due to being overworked and staying at a inferior hotel on layover.Fatigue is cumulative and after six days of flying combined by an inadequate hotel for rest it becomes a safety issue. Fatigues onset will come at a critical time and will lead to mistakes. I ill be more vigilant in the future and use the fatigue protections to prevent this. The company needs to maintain a better standard of hotels for layovers to ensure we get adequate sleep. If I have a repeat experience at this hotel on a layover; I will remove myself from the next day's sequence.
A321 Captain experiences a bad over night due to a very noisy hotel. During approach at the end of the next day; the First Officer calls for the missed approach altitude to be set and the Captain inadvertently initiates a climb. Autothrust and autopilot are disconnected and the approach is continued manually.
