OK everyone what is your take on this, and if you fly a Saab 340 what does your company wants you to do.
After NASA did their ice testing in a twin otter they discovered ice does not bridge on boots anymore. They found that todays technology in boot manufacturing minimizes the chances of bridging; and because of that our company came up with a new policy on how to function our boots in ice.
On the Saab we have two choices to operate our boots. One Cycle, or continuous. One cycle inflates the stabilizer, outboard wing, inboard wing, stabilizer. With continuous on it does one cycle every three minutes.
After the NASA study our company now wants us to operate our boots in continuous mode if we are in any ice. After following this procedure I found that in light ice I never get a good break.
The only way I have found to get a good break is let the ice build to mabey a 1/2 of inch then give it a one cycle. This is of course dependent on the type of ice too. Clear ice gives a better break than Mixed or rime ice. I think that is because of the air bubbles that are in the rime and mixed ice.
