Capt Stable
The stall strips ensure that the outer wings generate lift, when the inner wings have reduced or no lift, thus assisting lateral stability (and providing effective ailerons)
What would happen if the outer wing stalled first?
What happens if you take flaps and increase the lift in the inner wing section?
Reduced lateral stability.
Intercepted
Why don't you read the original question again? The OP wishes to know the incremental landing distance, not the approach speed.
The type of PA28 is irrelevant, because this data is not published in the POH.
