Thread: Beware of flight into icing conditions!

  1. #1

    Default Beware of flight into icing conditions!

    It happened to me today in the Skyhawk, trying to cross Greenland. When the windshield started icing up, I thought it was a cute touch to the graphics. When the pitot system failed and engine started losing power and I couldn't find the handle for the carb heat, things got very interesting. No carb heat and the pitot heat switch appears to be a dummy.

    For awhile, it looked like I was going to mush down onto a glacier, but I managed to hold her up long enough to get down to lower terrain and the problems started clearing up.

    Nothing like this ever happened in fs9.

    Haha, keep away from anything moist (e.g. cloud) when the OAT is below zero celsius. Icing seems quite well modelled in msfs to me, though I don't remember seeing it in previous sims. New simmers should also be aware that due to the Venturi effect on the carburettor, carb icing can occur at significantly higher temperatures and use carb heat for descent or any power setting below the green arc. In the RW, we also check the power drop using carb heat in our pre flight and never have it set to taxi due to the risk of sucking dirt into the carb ( easy to forget to push it back in after landing).

    For new simmers wondering why there is carburettor heat on the 152 and not the 172, the 172 has fuel injectors rather than a carburettor (unlike the old 172s I have flown).

    A brief addendum to Ian's excellent post: A C-172 is not certified for flight into known icing conditions, which is also true of most other singles and many light twins, so avoiding icing conditions (or forecast ice, for that matter) is prudent as well as being the only legal way to go. Of course in a sim...

    I kind of hate how FS2020 modelled icing. yes it's nice and all, but I hit a cloud and it's 1 degree below and within seconds I lose all the ability to see. I talked to a friend who flies 737's and mentioned this and he feels it's over exaggerated too much. he doesnt think it should ice over that fast. just food for thought. i've not had ice in real life, nor do I care to in a 172, FIKI rarely ends well for ill prepared airplanes and i'd rather not become a statistic.

    Is there a setting so the ice WILL NOT effect the 172 at all?

    There’s a setting under options/assistance/failure&damage...
    “Icing effect” - the options are ON or VISUAL ONLY
    Of course this will affect all aircraft.

    Hmm, I have it set to that already, yet, the effects of the ice still takes me down faster then ever.

    Good to know. So flying into unexpected icing is fine, then?

    Sorry, just had to.
