Slat system 1+2 failure is a lot of training value failure. With this Failure you get in Alt Law without protection which is different from reduced protection. You will loose on PFD S, F speeds, no speed trend arrow and display of VLS with VSW is missing. It requires good raw data flying with selected speed targets. Since trend arrow is not there loss of speed cannot be pre empted, requires frequent scan of speed. Since there is no stall protection if speed decreases towards VLS(which is not displayed) the aircraftwill not pitch down but will trim into stall. Good exercise to go back to basics.
