On take off - Flaps retracted at Vfto, no faster than Ver until flap zero.
On approach - Flap 18 selected at Vfto +15 (company minimum). Vfto +15 is often signifficantly below the max speed for extension of Flap 18, which is 200kt, 205kt, 210kt or 215 kt, depending on which airframe one is flying.
What part of this procedure is the incorrect speed?
Flaps still howl.
While on the subject of flaps. How can one type have so many different flap extension speeds for a given flap setting?
