Thanks for the posts guys. Had a look at the suggested book (on google books) and it said that the stall strip's job is to disturb the laminar flow at high AOA so that the buffet can be felt through the elevator. Ok, makes sense to me but that doesn't really mean that the stall strip affects the stall charateristics of the aircraft (when and how it stalls) but purely how and when the buffet is felt.
Any input regarding the apparent single pilot ops during this flight test?
