The US Army did much the same except we did all takeoffs from the ground after doing the Hover Check. We flew the entire procedure on Instruments....whence our take off from the ground....no need to transition from looking out side to looking back in during a critical phase of the maneuver.
We held Hover Attitude while adding Take Off Power to 100 feet AGL or well clear of Obstacles....then lower the nose by 5-7 Degrees and accelerate to Normal Climb Speed (60-80 KTS).
Take Off was into wind or as close as possible over the lowest obstacles.
It worked for every type of helicopter I ever flew.
No turns below 300 feet....and normal IF calls and procedures.
