ice where? Wings, carburetor, or inside of windscreen?<div class="ev_tpc_signature">

As far as I know, U.S. aircraft, at least those with enclosed cockpits, had a defroster system that would blow warm air on the inside of the windscreen. This basically worked like the defroster in an automobile. Carburetors also had a heating system to prevent ice formation. Pitot tubes often had electrical heating.

As for the wings and stabilizers, larger aircraft (cargo and bombers) sometimes had rubber boots fitted to the leading edges. If ice was detected, air could be pushed into the boots, expanding the boot slightly and hopefully popping the ice loose.<div class="ev_tpc_signature">

I know for sure that the B-24 Liberator and PBY Catalina had anti-icing boots on its leadig edges. Several

I know FW-190 had hot air ducts from the engine to the guns to prevent them from freezing at high altitude.<div class="ev_tpc_signature">

All of that and anti-ice boots on the wing leading edges. THink of it, the heavy bombers are thousands of feet in the air where the temperature is well below freezing point. If ice forms on the wings, it'll ruin your wing profile and therefore increase drag and decrease lift. Wich is very bad of course. That's why plenty of WWII aircraft had anti-ice boots on the wing leading edges. (system still used in today aircraft) It is basically an inflatable rubber strap. When ice begins to form, the rubber can be inflated and so break the ice. The black stripes along the wing leading edge are the rubber boots. I've never seen them on fighter aircraft, just bombers. And some aircraft that flew in low-level strike and in hot conditions appear to have them removed, probably for weight savings. Like the A-20's and B-25's in the pacific.

I always look at the boots in the skins. If they show paint-chipping, I know the skinner didn't know the stripes where not paint but rubber http://forums.ubi.com/images/smilies/10.gif There is not much point in having torn rubber flapping in the airflow, probably a aircraft with torn rubber boots would be grounded.

Thanks for the replies, makes sense for the big bombers. Didn't know for the 190, nifty system.
I wonder if we'll have those modeled in BoB. Would be nice. Using carburetor heating decreases power slightly (not much, around 75 rpm in a C172), wouldn't be a big issue, but since we strive for realism...

Everything with a variable prop has heaters in the prop hub to keep the hub oil from freezing
solid. I expect that also there were electric carb heaters at least in Russian and German
planes so why not the others too? Try running planes in the north where in the 40's there
are states that averaged -10F to -30F 2-4 months a year. It makes them easier to start too.

Ice is heavy as well as ruining your lift/drag.

I wouldn't expect a fighter to have boots running past the gunports. And I don't remember
any pictures of fighters with those boots but I never much looked. Gotta find some winter
pictures maybe. And boots can be painted on can't they?

I have 4 final exams tomorrow, one which I know I'm going to fail, one which I have a possibility to pass if i study, and another two that I should be able to ace if I play my cards right, no pun intended...

And yet, I have the insatiable need and desire to play X-Wing Alliance.

I don't know what to do.<div class="ev_tpc_signature">

Your exams are tomorrow???
That means it's too late to study- you wont retain any new information that you try to cram. You're better off distracting yourself somehow while putting your brain into neutral- it's probably too late to master transendental meditation. I suggest you try X-wing alliance.

BTW- this advice is not free, i will accept Visa or Mastercard.<div class="ev_tpc_signature">

I've been in your shoes every finals week since I returned to college. (And every mid-terms as well). Best to 'go with the flow' and play until 11 or midnight until you're slightly hypnotized and partially exhausted, and totally unable to question the contents of your notebooks. Then you can absorb the material blindly and without resistance, and sythesize it during a fifteen minute powernap right before your class. Don't let your brain go into REM sleep because then you'll just obliterate your newly loaded knowledge with unimportant dreams.

You can trust me. I'm about to graduate! http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif<div class="ev_tpc_signature">

The de-icing boots weren't always effective, read 'Fate is the Hunter" by Earnest K Gann to learn a bit about the boots in operation and for a first hand account of a DC2 almost overcome by icing. It's an excellent book and definitely one of the best aviation books I've ever read. Propellor icing was often combatted by shooting alcohol from the hubs, likewise the windshield was de-iced with alcohol and a device nicknamed the "elephant's ****" was used inside the cockpit to direct heated air at the windshield. Frequently, in bad icing conditions none of these devices was fully effective and many cargo aircraft were lost. If contemporary reports are to believed, the DC2 could carry a heavier load of ice than the DC3 and the C87 (cargo version of the B24) was hated and reviled because it would fall out of the air with only a thin layer of ice on the wings, possibly something to do with the high altitude optimised Davis wing.

it would be nice to have all the advanced flight controls of cfs2 fs9 and x, I would settle for realistic take off lenghts and power off glide slopes first and perhaps some real sense of gravity in game and feel of terrain while flying low alt, seems mountains or more like little lumps and hills.

Sounds very much like the TKS system used on Cirrus aircrafts !
