Air carrier flight crew reported exceeding bank angle during climbout in IMC. Flight crew corrected bank angle and continued flight uneventfully.
We departed ZZZ at around XA:01. As instructed; we departed on runway heading up to 3000 ft. During the climb; which was significantly bumpy and in IMC conditions; we were given a left turn. As the Pilot Flying; I noticed that the FO (First Officer); Pilot Monitoring; was a bit task-saturated cleaning up the configuration; talking to departure; tuning in a new altitude; and turning my heading bug. While banking left; I noticed that the windshield wipers were still on; so I quickly reached up to shut them off. As I shut off both wipers; I heard the audio warning 'bank angle; bank angle.' I quickly corrected the bank and continued the flight with no further incidents.The bank angle caution message was triggered when; I; flying in IMC conditions with no outside horizon reference; was momentarily distracted by turning off the windshield wipers. This led to an excessive banking angle during the left turn.Suggestions: To prevent such incidents in the future; it is crucial to maintain focus on the primary task of flying the aircraft; especially during critical phases of flight such as takeoff and climb. As the Pilot Flying; I should prioritize aircraft control and navigation over secondary tasks. The windshield wipers could have been turned off once the aircraft was stabilized on its new heading and altitude. If the pilot monitoring is task-saturated; I could assist in managing the workload; but not at the expense of aircraft control.
While Departing Runway XX on our initial climb; we got a bank angle" warning. Captain was Pilot Flying and I was Pilot Monitoring as First Officer. This was a very high workload situation as we lifted off. At approximately 500ft we got windshear; although no caution or warning came up. We continued to climb in moderate turbulence and IMC conditions when we got a turn to a heading from Departure. At this time we had both side windshield wipers on. I was very overloaded at this time; and the Captain reached up to turn off the wipers as to not exceed a limitation. When he reached up to turn them off is when we got the bank angle audible warning. The Captain immediately corrected the bank and the flight continued on as normal. The main cause was pilot saturation; which in hand caused the Pilot Flying to aid the Pilot Monitoring ultimately leading to taking eyes off the flight controls momentarily. Other factors involved were weather (moderate turbulence; IMC; windshear); and an MEL for the boom MIC being INOP on the FO (First Officer) side. As Pilot Monitoring; this caused me to have to use the handheld as my only source talking to ATC. My hot mic of being able to communicate with the CA (Captain) was also inop as part of the MEL. I believe these factors; especially the latter played a huge part in pilot saturation on my side. Suggestions: Keep flying the aircraft- Captain did a fantastic job flying the aircraft and showed great airmanship on the departure aside from the conditions and corrected Immediately. I would also suggest a change to the MEL we had; as it caused quite a delay for me to perform my duties as Pilot Monitoring."
