In the EC225, flown 3 axis coupled, the flight envelope is fully, and I mean FULLY protected. Inadvertent reduction of airspeed or descent to RADALT 150 feet, results in an immediate automatic reversion to 4 axis coupled and captures safe flight parameters.
These are called Hidden Protections based on the concept that if the EC225 is operated correctly, to a logical safe set of SOPs then in theory the crew will never experience these protections.
Of course we provide 28.5 x 2 = 57 hours of Type Rating Training in SIM and AC to provide the pilot with a comprehensive and fully formed model of how the AFCS, the FADEC and the Display system integrate to support the crew. We believe this is just about enough to get all the messages across and prepare the crew for safe EC225 operations.
I do not know how this compares with the average NS TR on L2 and EC225.
