Funny this has not been brought up before. Just had to do a contract with a B206 on Big rubber inflatables......... A real speedster she was. Anyway I had to get OAS carded for the Ops, so the owner and I went out (Hes a CFI) and did a few in a lake....... Real interesting if your not used to them. Most important is zero that airspeed and watch the flair (tailrotor in water is not good)before you go in.........In can get really wet in the cockpit if you dont. ha ha
Something else some dont think about is the fact that when your flying XC, its safer to put the float thing in water than land. Anything OTHER than zero forward speed on land and over she goes............
