Narrative:

We were being vectored onto the approach to runway 28L. ATC gave us a heading of 300 degrees and just as we crossed the localizer they gave us instructions to descend to 4;000 ft; reduce speed to 180 KTS; and cleared for the approach. The first officer; as pilot flying; armed the approach on the flight guidance panel and both the localizer and glideslope captured simultaneously. Given that we were crossing the localizer as it captured; the bank was a bit more than usual and; with the airspeed bugged to 180 KTS; the speed began to rapidly deteriorate. I yelled; 'watch your speed!' but the first officer did not react and within seconds the speed decreased to the point where we got the stick shaker. When the first officer did not react to that either I immediately took control of the aircraft and returned the speed to normal. We continued the approach and landed.

Original NASA ASRS Text

Title: An ERJ-175 Check Airman conducting IOE for a new First Officer took control of the aircraft when the First Officer failed to respond with appropriate thrust reponse to an aggressive loss of airspeed during an abrupt localiser and glide slope capture. The airspeed decayed to stick shaker before the deceleration was reversed.
