Autothrottle on the 737 set at Vref +5kts. 8kts is the gust value.
One airline I've flown at used Vref+10 as the minimum for RNP approaches. That was for -4,7,8, and 900s.
why would you do that? this makes no sense, first off, you would have to disengage the AT, and you are likely on idle descent...
