It seems Heli hit the tree straight without any technical issues.
looks like Heli wasn’t trying to land so a technical issue unlikely. But speed was low as a precaution.
what about sensors like terrain collusion device? Vision device? And aviators usually wear by pilots surely decrease visibility further.
It looks like IAF pilots need to spend more time on simulator/training rather than on Carrom board. Tri-service inquiry surely brings some light about IAF operational procedures.
Essentially, three types of on-board mission avionics are reqd for ensuring flight-safety when flying in bad weather/low visibility conditions over mountainous terrain:
Traffic Collision Avoidance System (TCAS)
Ground Proximity Warning System (GPWS)
Emergency Locator Transmitter (ELT) Beacon
For those helicopters designated for VVIP transport, the above 3 avionics are MANDATORY,
but it remains to be seen if any of them were installed on-board such Mi-17V-5s
