Old Akro, you are really banging the drum.
FGD, I could say the same thing about you.
The major flaw in the SIM session is that the aircraft was flown to a TAS of up to 140kt.and possibly more. But the incident aircraft never flew above about 112 kt CAS. Therefore the SIM did not fly the accident profile. WHY?
the report does not say the SIM simulation
tried, three times, but crashed on all three
. It says " ...about 140 kts (CAS) at which time because of aerodynamic flow around the rudder (sic) it became uncontrollable". This infers that the SIM session was broken off when the pilot lost directional control at 140 kts. (an an undisclosed altitude). Interesting, but not relevant. What is relevant is the flight condition at 108 - 112 knots CAS..
the SIM pilot is not reported as having made any comment on the controllability at the speeds exhibited in the incident. The SIM pilots comments are that the yaw was manageable at lift off, then challenging, then uncontrollable after an unspecified period with the aerodynamic load at 140 knots and above. The aerodynamic load can be expected to increase with the square of airspeed - so the rudder force required to correct the LH rudder trim at 140 knots will be very different than at 108 - 112 knots.
