Instructor is still in teaching and follow through mode?
Never done this.
There is only ever one person flying the aircraft. The is very limited value in taking individual controls because as we all know the effects are interlinked. You just end up building in problems and bug bears for later.
The other obvious thing is that the student hasn't understood the landing brief if it has been given at all.
Whats the back ground and experence level of your instructor?
