View Full Version : FS2002 contrails
10-14-2001, 08:20 PM
I'm sure you dont know any better than me, but in real life contrails depend on the weather conditions. For instance some times there are no trils at all, other times they are short, and sometimes they will stay in the sky for hours. It all depends on tempature, humitity, and altitude, and some others. Are all of these variables programed into FS2K2.

You know, I was wondering the same thing!!
Thing is, when you look at it from an implementation point of view, here were MS's options:
1) Simply make an, "Automatic Smoke" that is the same as the current smoke activated with the 'i' key, (although better looking and now engine-centered) but make it non-user controllable and have it turn on automatically at altitude.
2) Do as above but in the activation algorithm also include computations of ambient temperature and pressure for the given aircraft location to determine if contrails exist. Continually compute this as new conditions are encountered. Perhaps adjust visual smoke length by some equation related also to temp, press, (perhaps engine exhaust temp) and whatever else.
If it were X-Plane, I'd expect #2. (Just because they're obsessive like that. :) )
Thing is, with MS, it probably depends on the economics of the programming more than anything, and being that MS worked so hard on eye-candy in this version, the answer could be either one.
Anyone with a later Beta know anything about this?

I'd surely be hoping it's more #2 that FS2002 is going to recreate. Anyone keen to give us a definitive answer?

I read in the FS2002 forum that they came on automatically at FL300. I don't think pressure, humidity etc etc would have anything to do with it. Still, I suppose we can be thankful that there actually are contrails this time? :-hmmm

You are correct in what you state, they are based on nothing else but the altitude.

Yes you are correct in all that, but the "Contrail Height" varies daily and seasonally. Fighter squadron pilots are given the Contrail Height each morning at Met Briefing and also whether they are "Persistant" or "Short". It is important, tactically, to avoid trailing if you don't want to generate a huge "Dogfight".
Sometimes the trails are so persistant that it is possible to "Write" a drawing of something rather rude in the sky :-eek
I don't think that all this is going to be simulated in FS2002 :-roll

LAST EDITED ON Oct-16-01 AT 08:19PM (EDT)[p]And you've never done ANYTHING like that....Have you Peter :-lol

Well, I suppose I might have, in my youth :-eek I certainly wrote my wife's name in the sky over Hanover...It lasted for about 2 hours :-roll That wasn't rude of course!

That is some thing to suggest for a future version of FS. It has only been out for 2-3 days and we are already talking about the next version.

Well, i think that contrails are a very important part of aviation. How do you recognize an aircraft in the sky (im talking about the big ones, not the small ones that take off from the closest airfield)? By its contrail.
