GPWS, maybe?
With gpws flap mode off you dont have available its protection for a possible CFIT. If you do your final approach to a mountain instead of a runway, the gpws will not alert until too low gear. WIth GPWS in flap 3, you still have that protection, right?
But in case of flap and slata jammed at zero the precedure is flaps one only, why?
