**6.1 Technique of an experiment**

In realization of initial phase, being the final stage of the crew training makes tentative estimation of the crewmember action efficiency in the ONS localization. Formation of the particular situation arising in the IRLSS specific system operation is made on the basis of random sample by the Instructor.

Localization of the arisen ONS is made by each crewmember with the use of the on-board instruction from the operator's workplace disposed in the Main Control Board. In this case both a rigid copy of the on-board instruction, and its electronic version which is available in a format \*.PDF on Operator's Terminal 1 and Operator's Terminal 2, can be used without Mission Control Center recommendations.

Generated off-normal situations are characterized by different degrees of complexity in their localization:


For assessment of the crewmember gained efficiency the following is considered:


The increased duration of localization of failure indicates absence of attention concentration in some crewmembers that is connected or with realization of some additional activities, either with fatigue, or with presence of distracting factors.
