OK - my tuppence worth.
A towering take-off, in non-military terms, is there to get you out of a confined landing site, with you maintaining visual references until you can climb clear & accelerate to reach Vmini, (if expecting to become IMC). At that point you can couple the aircraft to its Flight Director systems, and climb for an IFR altitude.
This aircraft is extremely capable, but it will not do everything. It has an auto hover function (no Doppler required) that is incredibly accurate. It will hold a hover over where you've decided with a 40kt crosswind! The minimum height to engage that function is 30'. It also has a TU (transition up) function from that auto hover. However these are specialist systems that are demonstrated to pilots training on the machine, but you're not being trained to use them. They're there for the SAR guys.
My new employers Ops manual tells me that I need a minimum of 150m of lit runway to depart. That's there so I can reach 50kts (phase 5 or 7) or 55kts (phase 4) before I can couple the Flight Director. It's not just a guide - the aircraft won't play before that speed and if you're decreasing speed through that range, it will decouple the FD.
This was, in all probability, a preventable accident. Owners & inexperienced pilots believe, that if you have an aircraft that will do everything, that you can do anything. Training & experience help you to say no.
