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 initiate a go-around. The PM, on the other hand, said he believed that the PF was responsible for initiating a go-around. Thus, the PF and PM had differing understandings about whose role it was to initiate a go-around in the event that one was required. The NTSB concludes that the delayed initiation of a go-around by the PF and the PM after they became aware of the airplane's low path and airspeed likely resulted from a combination of surprise, nonstandard communication, and role confusion
