I am starting to use CEM seriously.

I have one question, What does the function: "Cowl or Armor Flaps" Do?

Which planes got it and what does it do?

Any tips or hint concerning routines when using CEM for the first times?

Cowl and armor flaps refers to radiator flaps. All planes have these in one form or another. In the P-47 its the flaps on the edges of the cowling, in the bf-109, its the radiators under the wings.

Openning the flaps increases airflow through the radiator/cowling, and cools the engine.

Open flaps will cause drag, and will reduce performance. Generally they are closed unless you absolutely need to cool the engine.

Proper use of the radiator is critical for long duration engagements...not understanding or using it properly will lead to premature engine cooking.

Overheat warnings vary from plane to plane as well as the maximum time the overheat message can be on before engine damage...with experience you find the edge of the envelope.


Knowing your plane is the key.

Opening the radiator increases airflow around your engine. This is the fastest way of cooling it, but at the price of increasing drag, thus slowing you down. You can open it fully or partially, the further you open it the better the cooling and the higher the drag. It is there for when you are in a pinch in terms of overheating, but the best way is to prevent overheating.

In my sig there is a link to a site with a CEM guide. You can read there for a lot more information. Have fun. http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

Are there more than one position for it? as i understand there is only two positions open or closed, am I correct? Varies this with plane?

Yes, I saw your site it works good in Opera and is now bookmarked, you have a new faithful follower to your site.

The CEM guide you are writing is very good, will you provide it in a printable form so one can print it and have it next to the computer?

thansk for all help.

Several positions...depends on the plane. Open, Closed, Position 2, 4, 6 and 8 I think it is. I don't pay much attention to the specific numbers...there's also Auto/Closed on some aircraft which is generally pretty good for controlling the system. I tend to fly with Auto/Closed or just Closed till I get an overheat warning and then I either go full open for a few seconds and drop back to Position 2 or keep it at a moderate number for better average cooling. Depends on the situation...if I want alot of speed I'll chop back the throttle and keep the rad closed or nearly closed.

From this quote I would say that you are flying the original IL-2. In IL-2 it works the same way, except you can only fully open or close the radiator. Only in Forgotten Battles do we get complex engine management, and that is what the CEM guide on my site is intended for.

That CEM guide will be incorporated into the FB version of the User's Guide, but currently the guide is still only for IL-2. That's why I put the CEM guide online only. So in the future it will be in printed form as well, but not for the time being.

Unfortunately I don't get to update my site all that often, maybe 2 or 3 times a month. Glad to hear the site works in Opera! http://ubbxforums.ubi.com/images/smiley/16x16_smiley-happy.gif
