Colgan Beech Winter Ops Question

Not to mention, as somebody stated earlier, Boots were never designed to be an Anit - Ice system. Unlike heated leading edges, boots have a finite lifespan. The rubber will stretch, tear, and gap, reducing the effectiveness of the boots.

Flying with the boots going non-stop is like driving on a wet highway, riding your brakes the whole time to keep them heated and dry. Sure, helps when you "HAVE" to stop... But is stupid.

Didn't they change the temps to +10 and vis. moisture to prevent ice ingestion on the saabs? or did they take that back.


I do love how Beech didn't even bother protecting the Vert. Stab... their answer,"It'll fly"

Exactly, let the ice build up, then blow the boots and get a clean break.

Thats how we used to do it when I was there over 5 years ago. If you blew the boots before enough ice built up to get scared then not much would break off. Let a good bit of ice build up and get the slight scared feeling and blow the boots and you would end up with a nice and clean leading edge.

The 41 couldn't carry nearly as much ice as the 1900, plus I only flew it for one winter and only flew less than 10 hours a month that winter, but the 41 seemed like it would clear ice better with less ice accumulation. From what I remember it would blow the top half then rotate to the bottom half or something like that...either way the rhythm of it seemed to break the ice better than the 1900 did. From what I remember the 1900 blew the whole boot at the same time though. Maybe current 1900 drivers can correct me if I'm wrong.

The 145 has the regular hot wing like most jets so its more of an anti-ice feature, but it still only runs after ice is detected. But I agree that using the boots as anti-ice seems a bit stupid.

+10c for engines.

+05c for boots.

I have heard through the grapevine that some people still don't abide by this rule. I haven't seen that though.
