All completely correct but there is one even bigger problem, most

Surely best practice is simply to keep the speed on until you have got

Isn't this what you taught us Chris?

Being constantly aware of one's airspeed is nothing more than basic


airmanship. Why and where would this not be the case?




Maybe when you are distracted having been surprised by a launch failure.

A basic standard of airmanship requires a pilot to expect every launch to fail. One is allowed surprise only when a launch DOES NOT fail. Inattention to airspeed is never acceptable even with a pre-solo student.
