Having now read many interesting posts are there really any simple answers to the following questions?Should EFATO training be undertaken when there is an inductee pilot in the left seat and the pilot in the right seat is undergoing assessment by an FOI to become a check and training captain i.e. the guy in the right seat is not at that stage qualified for the C&T role?Should EFATO training be conducted at a safer altitude? One post suggests that there may now be a minimum altitude of 1000feet in Australia whilst another suggests that certain manufacturers recommend a safe altitude of 5000feet. So what is really considered to be a safe altitude in an aging twin turboprop airplane?Should EFATO training always be conducted at or at least in the vicinity of an airfield where there are emergency services available?Should all commercial aircraft, irrespective of weight and capacity, have CVR? After all, the cost of installing CVR cannot be prohibitive for small commercial operators (as would probably be the case with FDR).If CVR had been fitted, and it is my understanding that this a recommendation of the NTSB for all commercial aircraft of 6 seats or more in the US, would investigators have a better understanding as to what went wrong on this tragic flight?
