Removing Torque Limiting also removed Torque Damping which easily led to torque surges caused by Pilot induced oscillations in the torque settings caused by Collective movement.
We had that inflicted upon us by that Operator as far too many of the young ones coming from the North Sea flying aircraft with bags of power came to the tropics and high temps to an aircraft that was weight limited rather than having excess power.
Handling techniques took a while to adapt.....but ultimately after enough serious over torques commonsense had the aircraft returned to the state the design engineers had decided upon.
I believe in CRM and have advocated for it long before it became as popular as it has. become.....as Crew Coordination, teamwork, and related concepts were part of flying a large crew served helicopter with a crew of Five or Six during normal Ops and more during other operations.
With the advent of radio communication even pilots flying solo can use CRM techniques during times of high stress or mechanical problems.
I am not faulting you for what you did.....am just saying such innovative measures needs to be well coordinated and no confusion be allowed to cause any new and extra problems.
What is unusual about the DFW scenario is the ugly is late in the approach and very near the ground leaving just a very short timeframe to counter the severe effects of the micro-burst but it is well within the abilities of the 212/412 modeling of the Simulator and one would hope the actual aircraft as well.
When we had free time for a Sim with no customers or maintenance preventing use of the Sim.... I used to set up the DFW Model or the Air Methods Blue Field WV model and fly those approaches several times solo in order to stay proficient.
Both of those were excellent tests of aircrew but each with very different underlying reasons.
One thing stands out from such training is there is usually more than one right answer and the discussion should be along the lines of what is the better way rather than what is the wrong way.
Wrong ways quickly identify themselves and can be discounted with a minimum of discussion.
Refusing to discuss something is sure the wrong answer in and of itself.
