The BEA report notes that the RHS airspeed is not recorded on FDR. So even though we know that the LHS and ISIS speeds matched again shortly after 2:11 we cannot be sure that the RHS airspeed also matched the other two. From this, many here have concluded that the PF may have working off incorrect IAS.
Of course, it's entirely possible that the RHS airspeed also matched the others. If the problems with two of the Pitots resloved themselves, why would the third not have as well?
More to the point, even if the RHS airspeed continued to differ from the others, would it continue to be displayed? Would the computer not substitute one of the other measured airspeeds for the one that it has decided is invalid? Or if it keeps displaying the invalid airspeed, would it not flag it as suspect?
Lets think about it a different way. It has leaked that the aircraft never achieved the abnormal attitudel law. For this to happen, It would seem that there was no synchronization of two airspeeds to form a "consensus" after the initial switch to ALT2 law.
