Do you know what kind of IFR equipment was installed in ill-fated Mi 17?
VOR/ILS, DME, radio altimeter? In what form (basic or proper HSI)? Autopilot? Flight director? What modes available? Coupled ILS approach available or they shoot ILS manually?
Then comes the question of IFR rating of the crew? How much IFR flying/aproaches in last 90days?
Is any above mentioned info known / available?
What has preliminary report said?
