A method of driving a main rotor of a rotorcraft in rotation while implementing an in-flight simulation mode that simulates failure of one of the engines of the rotorcraft. In simulation mode, and when a current speed of rotation (NR) of the main rotor is detected as being lower than a predetermined threshold speed of rotation (S), the simulation mode is kept active and a regulation command is generated in order to perform a controlled operation (A) of gradually increasing the power delivered by the engines by authorizing the limit imposed by a setpoint (OEI/2) for regulating operation of the engine in simulation mode to be exceeded. Said gradually increasing power is interrupted by the pilot staying under training and operating a collective pitch manoeuver of the blade of the main rotor providing a rotation of main rotor at the predetermined threshold speed in rotation.

A live virtual constructive (LVC) gateway system is configured to transparently separate, merge, and route data traffic between operator systems, live tactical Line Replaceable Unit (LRU) systems, and simulated tactical LRU systems. The LVC gateway is configured to receive LRU commands from an operator system, parse, the commands, and reconstruct the commands suitable for transmission to live or simulated tactical LRU systems. The LVC gateway is also configured to receive live and simulated status and target data from live tactical LRU and simulated tactical LRU systems, respectively, and merge the data for transmission to an operator system.

Systems, methods, and computer products according to the principles of the present inventions may involve a training system for a pilot of an aircraft. The training system may include an aircraft sensor system affixed to the aircraft adapted to provide a location of the aircraft, including an altitude of the aircraft, speed of the aircraft, and directional attitude of the aircraft. It may further include a helmet position sensor system adapted to determine a location of a helmet within a cockpit of the aircraft and a viewing direction of a pilot wearing the helmet. The helmet may include a see-through computer display through which the pilot sees an environment outside of the aircraft with computer content overlaying the environment to create an augmented reality view of the environment for the pilot. A computer content presentation system may be adapted to present computer content to the see-through computer display at a virtual marker, generated by the computer content presentation system, representing a geospatial position of a training asset moving within a visual range of the pilot, such that the pilot sees the computer content from a perspective consistent with the aircraft's position, altitude, attitude, and the pilot's helmet position when the pilot's viewing direction is aligned with the virtual marker.

A system and method for training a pilot to operate an aircraft in sudden-onset reduced-visibility conditions is disclosed. The system includes electrooptic material having an optical transmittance that varies with an electrical signal applied to the material and a power supply to provide the electrical signal to the material. The electrooptic material is disposed to restrict the pilot's visibility outside the aircraft when the electrooptic material is in a low-optical-transmittance state. The system further includes a flight-safety sensor that sets the output of the power supply to correspond to an optical transmittance state of the electrooptic material that does not substantially restrict the pilot's visibility outside the aircraft when flight conditions are deemed unsafe. The method includes reducing the optical transmittance of the material to restrict the pilot's visibility outside the aircraft in a manner unexpected to the pilot at the time of the transmittance reduction.
