Bloggs suggestion was for an automated callout at Vref-10 as a fail safe, not as a replacement for SOPs.

It seems reasonably safe to conclude that no one in the flight deck detected the airspeed decay before the failsafe warnings activated - hence no SOP calls. This accident is a reminder of all the things that could never happen to us - right? The message on what distractions were present will have to wait until the final report, but the time to seriously look in the mirror is now!

While playing with UAs the other day in a different type, ended up with a nose high and subsequent stall due to undetected full nose up trim - recovered after retrimming but highly doubt we would have stayed upright in the aircraft as long as we did in the sim before noticing the trim. We had both pilots holding full forward stick and could not get lower than 10 NU - at altitude, we had insufficient thrust to prevent the stall at that attitude.

Very sobering in that I have not previously included trim in my UA recovery plan. However, unlike some previous posts, I would never consider trim as a means of changing the attitude, only as a way of ensuring that adequate elevator response was available.
