Appendix 3-C - Functions and Subjective Tests

1. Discussion

Functional and subjective tests of simulator characteristics and systems operation will be evaluated at each flight crew member position. As appropriate, these shall include the cockpit check, system operation, normal, abnormal and emergency procedures using the operator's operating procedures and check lists. This assessment is to include operations under the full range of environmental conditions (winds, density altitude, etc.) in which the rotorcraft would normally be expected to perform.

Initial evaluation shall include functional checks from this Appendix as appropriate. If required, TC may elect to focus on simulator operation during a special aspect of an operator's training program during the functional check portion of a recurrent evaluation. Such a functional evaluation may include a portion of a LOFT scenario or special emphasis items within the operator's training program. Unless directly related to a requirement for the current certification level, the results of such an evaluation would not affect the simulator's current status.

Operational principal navigation systems, including but not limited to, Electronic Flight Instrument Systems (EFIS), Flight Management Systems (FMS), Global Positioning System (GPS) and Initial Navigation Systems (INS) will be evaluated if installed.

The ground and flight manoeuvres which shall be evaluated, as appropriate to the level of the simulator and the visual and special effects evaluations, are in the following table.

All systems functions will be assessed for normal and, where appropriate, alternate operations. Normal, abnormal and emergency procedures associated with a flight phase will be assessed during the evaluation of manoeuvres or events within that flight phase. Systems are listed separately under "any flight phase" to assure appropriate attention to system checks.
