Firstly, let's note that the cause of the Ethiopian Airlines crash has not yet been determined. In the case of the Lion Air crash, the problem was not that the crew were unaware of the airplane's attitude (it was daylight in good weather, and they also had functioning airspeed indicators), it was that the control system kept resetting the longitudinal trim incorrectly in response to a faulty angle-of-attack sensor, and the crew did not follow the procedure to disable it from doing so.
