## 4 Empirical Analysis
### The Second-Stage Questionnaire Analysis
#### 4.2.3 Criteria Analysis of Questionnaire  
From the weighting values listed in Table 8, the competencies' weighting values and importance of different scenarios that the flight crew was faced with should be determined to cope with these emergency situations. Aspect 1: Take-off with different tailwind but not informed: Helicopter operation relies on VFR mainly; it was short of a standard airfield and without meteorological personnel to offer a weather report. To prevent LOC-I occurrence, the flight crew should reinforce the \"Communication\" (0.577) and \"Problem Solving and Decision Making\" (0.423) CRM criteria. * All systems should be checked in accordance with the procedure before take-off. If there is any system failure or damage (such as Test No Go), the flight crew should discuss it orally. If the ground crew witness a smoking situation (such as engine overheating), they should notify the flight crew with hand signals, which is \"postural communication,\" to shut down the engine and extinguish the fire. Alternatively, after finishing radio system failure troubleshooting, which needs a control tower to conduct a radio check. All the situations mentioned above belong to the scope of communication and a pattern of two-way communication. [PERSON] [40] points out that the receiver can evaluate and judge the message from the sender; we may conclude that this is good two-way communication. Good communication depends on effective verbal or non-verbal language, which includes eye contact, body language and hand gestures. The flight crew should have been aware of basic communication problems first and fully understood that effective communication is one of their responsibilities [41]. * Aspect 2: High-altitude area or high payload made horsepower insufficient: The helicopter operates in a mountainous or marine area, which is often complicated. To prevent LOC-I occurrence, the flight crew should reinforce the \"Problem Solving and Decision Making\" (0.445), \"Teamwork\" (0.290), and \"Communication\" (0.264) CRM criteria. * The flight crew should choose from multiple alternatives or propose different solutions under extreme time pressure [31]. The judgment of pilot depends on their attitude to handling the crisis and their risk evaluation capability, which includes their personal knowledge, skills and experience, to generate a suitable decision and solve the crisis they are facing. All the factors mentioned above are related to flight decision making; this requires clear and specific responsibility allocation among the flight crew and a full understanding of cockpit instrument monitoring and the outside environmental situation. The message sends out its demand, is understood, and then action will be taken. If the action matches the expectation of the sender, it is an effective communication and flight safety can be achieved effectively. * Aspect 3: Multiple external NAV failure. NAV capability deteriorated: Currently, the light aircraft visual flight corridor has an area of responsibility, flight route altitude restriction,weather constraints etc. Since there is no accurate reference available, the flight route obstacles are altitude and location along the visual flight corridor, low-visibility weather, arrival and departure separations; the helicopter location relies on radio traction, which might be ineffective when operating within mountainous and marine areas outside of the radio-monitoring range. Furthermore, poor weather conditions are an issue. To prevent CFIT occurrences, the flight crew should pay attention to the \"SA\" (0.333), \"Problem Solving and Decision Making\" (0.282), \"Application of Procedures\" (0.209), and \"Communication\" (0.176) CRM criteria. The flight crew should evaluate the conditions of their flight environment at all times and ensure they are under the best SA conditions. This is not an easy task even for a veteran flight crew. It requires the flight crew to obtain all the flight information, fully understand the whole situation and follow suitable rules.
