H65 Floats

Question 0

How long will aircraft float with floats deployed

Answer 0

4 minutes in sea state 2 with all 4 deployed with the water line below the cabin floor

The floating helicopter should remain stable enough to tow in conditions up to Sea State 5 and remain afloat, with the loss of one rear float or loss of one airbag in one of the forward floats, for at least 12 hours in Sea State 2
