The NASA video does not create a simulation of the flight conditions for the accident. It explains tailplane stalls as a function of icing within a controlled environment.
It would be a truer depiction if a simulation is made (using NASA software) showing the elements of flight where atmospheric conditions are known to be variable.
Where did so much ice come from? Is the fuel temperature causing condensation on the wing surface (ethanol)? What change in temperature is too extreme to change from flight levels as indicated? Why isn't the de-ice system keeping up with conditions?
There is a point of order regarding the principles of this flight but not its elements.
Is the Dash-8 STOL wing?
NASA/TM—2003-212115
A high-fidelity simulation model for icing effects flight
training was developed from wind tunnel data for the
DeHavilland DHC-6 Twin Otter aircraft. First, a flight
model of the un-iced airplane was developed and then
modifications were generated to model the icing
conditions. The models were validated against data
records from the NASA Twin Otter Icing Research flight
test program with only minimal refinements being
required. The goals of this program were to demonstrate
the effectiveness of such a simulator for training pilots to
recognize and recover from icing situations and to
establish a process for modeling icing effects to be used for future training devices.
