Whatever the cause
We don't know what happened to the flight. Hopefully the G1000 has an SD card for flight log.
My condolences go out to the deceased pilot and his/her family,the flying school and the instructor/s who trained and looked after the trainee.
Having been flying around this part of Vic for few years now and I can say that weather around YBLT, the southern slope and ranges is particularly challenging. I am not implying that it is the causal factor for this accident because we don't know yet.
Break break......not implying anything
What is truely missing? The teaching and assessing TEM,NTS in accordance with CAAP 5.59 and MOS Part 61.
Too often,Instructors make decisions for students. When student make a wrong decision they get shouted at. What about demonstrate, direct and monitor situational awareness and decision making ? What about read the CAAP and few other human factor books on aeronautical decision making?
