    Ethiopian 737-800 Max crash - No survivors

    in Aircraft Incidents and Accidents

    Posted

    One of the earlier links in this thread took a quite different tack, and explained the intention of the MCAS as being to generate increased 'pull' on the control column, so encouraging the pilot to ease it forward. I can't say I followed the logic of that, although in a genuine near-stall situation, that may well be one of the effects???

    My understanding is that there is a certification requirement that as the AoA increases as the control column is  being pulled back, the pressure required on the control column should not decrease. 

     

    For the MAX, the aerodynamic effect of the larger, more forward engine nacelles led to a decrease - hence the decision to feed in nose down trim via MCAS as a quick and dirty solution to the certification problem.

    The GA AFR is good for RAA as well, just get the GA instructor to send in the form.

    Don't even need to do that - I just email a scan of the logbook page to RAAus.  Same with GA endorsements (RU, MPPC, etc, also for your X-country on your RPC).
