Yes, which is why the regulators should include mandatory training in 'military' IF take off techniques as well as all the other IR stuff - you don't necessarily have to test it on an IR check ride but if it is documented as having been taught (even just in the sim) you are giving non ex-mil pilots another string to their bow when the 'job really needs to get done'.
Comming from the military and such take offs and being used to these, they arent possble to legally be performed in the most HEMS aircrafts.
For H145, it has been "TDP and further acceleration to VTOSS can be accomplished using visual references", which means 45KIAS.
The new V.10 software (Automated T/O and rejection) makes it legal from TDP (if memory serves correct), which mostly means 200 feet above the elevated heliport.
As I understood it from higher up in the thread, this EC135 did not have any Autopilot with Upper modes ?
Not having such, the military IMC T/O wouldnt count and also not make PC1 possible.
