RENTON, Wash. -  

For those viewers who love choppers, here’s some interesting video of a test of Chopper 7’s emergency float deployment system.

 

If an in-flight emergency required the helicopter to land in water, the pilot can trigger the system which causes floats on the chopper skids to inflate.

 

Chopper 7 mechanic Terry Parrish and pilot Jamie Hansen provided some facts about the system.

 

  • A test of the system is conducted every three years.

 

  • As part of the test, the floats must hold pressure overnight.  They are deflated and put back in the "float bags" attached to the helicopter skids the next morning.

 

  • The float system has never been used for a real emergency on Chopper 7, but given the surface area that water covers in Western Washington, it is essential for safe operation of KIRO 7’s helicopter.
