Therein lies the rub: floats can be manually operated prior to impact,
All three filming accidents in recent years involving the permanently float equipped R22 mariner resulted in a capsize or sinking, despite loss of control occurring from low speed and below 50ft. The recent immersion in oz of a jet ranger with deployable floats was a near thing with it floating on its side in the water and then sinking (much) later.
OK R22 and 206 are miles away from Pumas, but in general are we expecting too much from floats?
