was VLS available? and if so was airspeed already below VLS? and if so will it guide to reach VLS?
Interesting.
For the FDs to reappear, if I am correct, they need 2 airspeed indications in agreement. As both recorded airspeed indications were different, probably the unrecorded one was in agreement with one of the recorded. At that time, both recorded airspeeds were below VLS, one slightly above 200, the other one around 100, and the VLS was around 240 if I get it right from the QRH.
Now, the automatic speed protection you mention applies if VLS is approached from above, but would it apply if the airspeed is already and suddenly well below VLS ?
Also, such automatic speed protection applies for a climb scenario. Would the FDs command a temporary descent in order to get back to VLS ?
