Dual pitot static failure
In normal law a dual pitot static failure, (ie ICE)
will cause a result similar to this.
Logic is the computer follows the two inaccurate ASI which over read ie barber pole.
This will Cause alpha floor and with 15 degrees air nose up. See standby ASI, decreasing (good indication) see power vs attitude in qrh.
Full stick down will not respond in normal law.
I tried this in the simulator some time ago in 2001 (it may have changed.)
Quite scary for the poor trainees.
