I have a few questions about Icing and the way it is modeled in FS9COF. Just a few basic thoughts I have as a base of knowledge include the de-icing of the props (if you are in a prop) structure de-ice, and leading edge (wing) de-icing. The later being an example of a Cessna P210, where you can cycle the boots to rid the leading edged of the wings of any ice that may have built up. I also keep in mind that not all aircraft feature all the de-ice systems that may be available. .Lastly, I am using the term anti-ice is to keep ice from forming as de-ice is to rid a surface of Ice, as in the boots on a Cessna P210. So here are a few questions in relation to FS9COF, even if the above basic statements are not exact as in the real world, my hope is to make the questions relative to FS9COF clean and simple to address. So here we go:1. Even though in the real world there are separate switches for the various de-ice and or anti-ice functions, is there a key stroke or other command that turns on all available de-ice and or anti-ice features at one time? This is kind of like hitting ctrl-E to start all engines. Again, it is not the real world way, but I am curious if the command exists as I can

might want to search this subject...it was discussed extensively in one thread at least within the last 4-5 months or so

If you have a post number or link I would appreciate it as I seem to not be able to locate it. I did search prior to the post as well. Also, if you or anyone else have any comments on the key command and the the other questions I would appreciae it. Thankk you for your time.Mark.

I had the experience in a twin-prop (SF340B) in near freezing drizzle of taxying to the runway (a long trip at KMSP), taking off, and then starting to stall a couple of hundred feet up. Apparently I picked up structural ice during the taxi and most during the take-off.I restarted keeping deice on for the taxi, off for max power for the TO roll and lift off, then back on ASDAP and the problem did not appear.I also found similar problems in such freezing precip on finals at KDLH but managed a go-around with icing activated and landed in a much better speed and attitude.So I'd say yes, structural icing is indeed modeled.Note that it is possible if using FSUIPC and/or AS2004 to disable icing or turn on icing in clouds, etc., I leave icing enabled and during approach in cool precip feather insure it is turned on. It can be turned off if necessary for a go-around to get max power, and most jets appear to have enough power reserve to leave it on for a GA or with a long runway even on during TO.

Thanks Ronzie.I appreciate the imput. I will see if I can get the program you mentioned installed. It sound great. I already have the FSUIPC installed so we will see.Thanks agian.Mark.

Hi Mark,Here is a link:http://www.hifisim.com/Hope this helps,JimActiveSky Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg

Thanks,I am still working with the add-on program in an effort to have the icing present.Agian thanks.Mark.

One thing that can help to see if icing will occur is to have an OAT gauge or readout somewhere. This applies mostly to structural icing.As for carb icing, it also applies but you probably know that in carburated engines the OAT can be much higher but icing can occur even at mild humidity due to the sudden temperature drop of air passing through and exiting the venturi area - at least I think I've got that right.Icing can also occur routinely in jets and turbines as well - I don't recall the theory but on some panels there is a caution annunciator that indicates engine deicing off.Back to the main subject:When you say "working with the add-on" I'm not following your meaning. Did you purchase AS or another weather program? If so, and it uses FSUIPC, be sure to read the options section and the best FSUIPC settings for your desired environment. For AS2004, if you have it, be sure to download the latest beta. The link is posted on their support conference here on AVSIM. You will find more options than in the standard product so check them out carefully. Try it with FSUIPC set to minimum weather options and let AS2004 handle everything.If you want to look for real icing conditions, go to www.wunderground.com and enter an airport ICAO code. Then look at their historical data from early spring. (You can also click on show metars.) When you find a date that has the conditions you want, low surface temps and precip as liquid, not snow, you can download the archived weather for that date from AS2004, maybe save it as well in your own archive, and that will give you a testing environment to experiment with icing conditions. Rain at about 40 degrees F or slightly lower will turn into freezing rain as you climb. I think that is what you may be looking for.

this is a subject that is near to me. In researching the systems for my Grumman Widgeon, I wanted to have real effects for ignoring things like engine temps and icing.. etc. Icing does work very well in FS9, but it's hard to tell. (unless you fall out of the sky, as mentioned.) AFSD is a great program and will display ICE WEIGHT.I currently have an icing system working on the Widgeon and failure to recognize the ice buildup has catastophic results. (Im not emotionally attached to my virtual pilots!)i will soon be adding visual cues to the degree of icing.if you're affraid of killing digital pilots, dont fly my widgeon.. it's frightening!! lolI cant find the AFSD link, if you have trouble let me know.joe
