Structural Ice in FSX is very dumbed down. Here for more readinghttp://forum.avsim.net/topic/359060-ngx-feature-request-structural-icing/page__fromsearch__1JB

Ok, thanks!

I can't speak for any other airline, but for us:Cowls:1) On the ground - The cowl anti-ice system must be ON when the OAT is 10°C or below and visible moisture in any form is present (such as fog with visibility of one mile or less, rain, snow, sleet and ice crystals). • The cowl anti-ice system must also be ON when the OAT is 10°Cor below when operating on runways, ramps or taxiways where the surface snow, ice, standing water, or slush is present.2) In the air - Icing conditions exist in-flight at a TAT of 10°C or below, and visible moisture in any form is encountered (such as clouds, rain, snow, sleet or ice crystals), except when the SAT is -40°C or below. • The engine cowl anti-ice system must be ON: – When in icing conditions, or – When ICE is annunciated by the ice detection system.Wing A/I:1) On the ground - The wing anti-ice system must be ON for takeoff when the OAT is 5°C or below and visible moisture in any form is present (such as fog with visibility of one mile or less, rain, snow, sleet and ice crystals). • The wing anti-ice system must also be ON for takeoff when the OAT is 5°C or below and the runway is contaminated with surface snow, slush or standing water. • When Type II, Type III, or Type IV anti-icing fluids have been applied, the wing anti-ice system must only be selected ON, if required, just prior to thrust increase for takeoff.2) In the air - Icing conditions exist in-flight at a TAT of 10°C or below, and visible moisture in any form is encountered (such as clouds, rain, snow, sleet or ice crystals), except when the SAT is -40°C or below. • The wing anti-ice system must be ON: – When ICE is annunciated by the ice detection system, or – When in icing conditions and the airspeed is less than 230 KIAS. • Do not hold in icing conditions with the flaps/slats extended.Just for clarification - When it refers to OAT, that is the temperature you get from ATIS/METAR observations. What you get from the PROG page in the FMS is SAT, and it can only be used for the "in the air" portions where is refers to SAT is -40C or below. This is because the SAT readouts can be wrong when the plane is on the ground. This is more of a RW problem, and it has to do with the probes getting heated by the sun, etc. For instance, 2 days ago I was in KDTW, OAT was 1C according to D-ATIS, and our SAT readout was 9C. This info was written by a lawyer. I know it's not the easiest thing to read, but now you know what it looks like in the manuals. :-)

Thanks alot for your very thorough answer Charles!

I started that thread so I already know about it thanks :wink:In this thread I was more looking for an answer if the NGX indeed is affected by icing conditions when it comes to performance etc (I know visual icing effects are not modelled in the NGX).

I had been wondering if it was modelled too. Thanks for getting the topic going!

Yes, would be interesting to know if operating in icing conditions without using anti-ice in the NGX will in fact make any difference or even getting yourself into trouble like you would IRL. Up until now I've been using anti-ice since I always try to mimic real world OPs as close as possible.

To answer your question. The only icing the NGX will be affected by is default ice weight only. It will accumulate in "FSX Severe icing layers at a rate of 0.1% of empty weight per minute. It will take 15 minutes in severe icing conditions with AI off to notice a hit on the NGX flight performance.There are third party options to create a loss of lift and decrease critical angle of attack plus create uncommanded roll and pitch events as ice accumulates, but they don't fully work with the NGX.Sent from my iPhone using TapatalkJB

Ok, thanks for the info. This means at least to some extent the NGX is affected when flying in icing conditions.

Yes just like the default aircraft. But IMHO you would need to fly circles in the layer long enough to cause an issueSent from my iPhone using TapatalkJB

Do you know if playing with the icing settings in AS2012 makes any noticeable difference?

Yeah, if you move the AS2012 icing sliders all the way to the right (Min and Max), then everytime AS2012 creates an icing layer, it will be severe.This is how I set it up. JB

Thanks, I'll try that.
