Narrative:
On [a] flight to ZZZ we had the stick shaker go off in the aircraft because we got too slow; while intercepting the ILS. It was my leg and the aircraft was on autopilot at about 5000ft. The captain and I were involved. We were getting vectored for the ILS and finally got cleared to intercept the course on a heading so I armed the nav to intercept it. During this time; I started to slow the aircraft down from 230kts which was our last assigned speed. I put the speed brakes out and was waiting to start configuring at the right speeds. It seemed to me that we were given a heading inbound a little late which would end up taking us through the course. Right before the aircraft going through the course; we got cleared for the approach so I armed the app. At this time it took the aircraft some time to intercept the course while switching from navigation to the app mode; while flying through the course at the same time so I pressed the touch control steering (tcs) button to bank a little more and help it intercept the inbound course. When I started to bank; I realized that we needed to start dropping the flaps because we were getting slow and I left the speed brakes out so when I was about to call for the flaps; I got the aural message 'bank angle'; I had banked through the 45 degree mark. Almost instantly we got the stick shaker and the captain took the controls and recovered right away. We continued the approach and landed.configuring early would have prevented this whole situation. But I waited too long to slow down and lower the flaps; and when the aircraft was slow enough for us to lower the flaps; we were dealing with intercepting the course inbound on the ILS and got too slow.
Original NASA ASRS Text
Title: A regional jet flight crew reported an unstable flight condition while performing an instrument approach. Aircraft limits were exceeded and a deterioration of airspeed resulted in generating a stick shaker warning.
