All this talk of flap operation causing problems when turning base to final - surely one shouldn't be altering flap setting whilst turning?
Apart from the distraction, there is the risk of asymetric flap (the starboard flap is driven directly by the motor, the port one by cables) when operating them and for that to happen when going round a corner isn't exactly ideal....
As for rtl's FRA150 - whatever he asks it's worth it, you have to see it to appreciate just what a nice example it is.
