If I understand what you are saying (?) your coding/RNP can't handle 160KIAS from a Cat C aeroplane. Why will you not accept that Cat is based on Vat, and approach speed is normally at least 5 kts faster than that?
it also shows why there are known issues with RNP traffic vs non-RNP traffic. There are plenty of stories and dialog about the RNP ac being too slow on final. That is one of the reasons.
The relevance to what Cat a 737 is?
