Yip, you´re right.
And at that position, you´re approx. 50cm above the ground...or maybe 70cm?
Even Rock climbers do not need to secure themselves when in a training hall until they climb above 2 m...

Don´t remember which SB it was...but pilots need a ladder for daily inspections anyway, as the tail rotor and the TR drive shaft needs to be check on each "Before Flight"-Check........
