Hello all.
i just checked one of the previous aircraft I used to fly, equipped with a stick pusher system, this is what I found :
The push force felt at the control column is approximately 80 lbs, which is adequate for stall
correction, but can still be overpowered by the pilot in the event the system cannot be
disabled.
NOTE: The number 1 and number 2 computer must both agree to push before the stick
pusher can be activated.
The stick pusher will activate when all of the following conditions are met:
• #1 STALL SYST FAIL, #2 STALL SYST FAIL and PUSHER SYST FAIL caution lights are
OFF.
• The airplane is airborne.
• The airplane altitude is greater than 400 feet AGL.
• The airspeed is less than 200 -
4 KEAS.
• The stick shakers have been activated by both systems.
The only thing I have difficulty to understand is why Boeing in the first place didn't connect the MCAS system to both AOA, exactly as stick pusher was in my previous aircraft.
now, not writing as long post about it, but the mcas issue is not only a design problems ... We can clearly see a tendency in the world of pilot to loose confidences in manual and basic flying skill in the modern aviation world. I would like to believe authority will not only react to fix the MCAS and that it, it is applicable to all the aviation world and instead of have more and more automation because pilot are more and more crap, we should maybe put back the pilot in the center of the loop and ask / help / train them to have their skill up to the task.
