Always thought the Agusta SOP of flying over water with floats armed was superior and a natural evolution over the old S76 (and others) restriction of limiting arming by airspeed. We blew lots of floats in the 76 at 140 knots with only embarrassment as a consequence. After we got the belly sensors to auto inflate all we really needed was a guard on the manual activation button on the cyclic, that alas never came.
Glad Agusta never backpedaled on SOP after the first few inadvertent float deployments.
