Ref speeds

Just to clarify the speeds I quoted at post 508 were for a landing weight of 24000kg and used to ilustrate the dangers of low speed - why 24tons? - aprox 18000kg Aircraft dow + 4000kg pax + 2000kg fuel = 24000kg.
Acording to post 655 the ntsb are quoting a vref of 119kts. we do not know if that is for flap 15 or 35 but in either case is for a landing weight greater than 24000kg.
This does make my figures conservative as with inc ref on, the adjusted vref would be Flap 15 = 139kts and flap 35 = 134kts.
Q How easy is it to become distracted and not increase power on level off? A Very.
probably far more on this thread than we care to admit have had a oh FK moment.
