the FS's uncertainty about whether he had the authority to make a go-around decision could have stemmed from confusion due to the inconsistent written policy in this area. In either case, the PF's deference to authority likely played some role in the fact that he did not intiate a go-around. The PM, on the other hand, said he belived that the PF was responsible for intiating a go-around. Thus, the PF and PM had differing understandings about whose role it was to intiate a go-around in the event that one was required. The NTSB concludes that the delayed intiation of a go-around by the PF and the PM after they became aware of the airplane's lowpath and airspeed likely resulted from a combination of surprise, nonstandard communication, and role confusion
