What is the maximum indicated airspeed with float bags armed or inflated?

• A. 85 kts
• B. 90 kts
• C. 95 kts
• D. 100 kts

Answer: (B)

Float bags change the helicopter’s aerodynamics and load paths. When the bags are armed or inflated, they add drag and alter the hull’s shape, which increases the dynamic-pressure loads on the flotation gear and affects stability and control during flight. To protect the float system and maintain predictable handling for water operations, the aircraft is limited to a lower indicated airspeed in this configuration. The published limit is 90 knots indicated airspeed with float bags armed or inflated. If the floats aren’t inflated, higher speeds may be permissible, but once armed or inflated, you stay at or below 90 knots to ensure safe performance and prevent damage.
