So I will assume it is same in B737. A faulty AOA sensor can make the Elev Feel Computer malfunction also.
Hope that makes sense?
Feel Diff Press
But there was no report of hydraulic pressure falling. So could the Feel Diff Press have illuminated due to elevator pitot disagree? The disagree, itself, triggered by a faulty alpha vane?
