drallabco Posted January 12, 2019 Share Posted January 12, 2019 Anyone who knows anything about aviation weather knows that for structural ice to form, the temp can be anywhere from 2°C to -20°C and that there must be visible moisture- clouds, rain, mist. I get that friggin inlet ice warning on every flight when it's clear and a million. Maybe DCS doesn't have a way to know if you're in visible moisture, but I'm pretty tired of hearing that advisory pop up when it's physically impossible that ice is forming.

Tretton Posted January 13, 2019 Share Posted January 13, 2019 I’m not a fighter pilot but I am a civian pilot. And if the laws of nature are the same for military jets as for civilian, the above statement is correct. Link to comment Share on other sites More sharing options...

drallabco Posted January 13, 2019 Author Share Posted January 13, 2019 It’s been discussed at length ;) https://forums.eagle.ru/showthread.php?t=215188&highlight=Inlet Hadn't seen that before. Still no response from ED on the issue though. The natops even states conditions for when you get an inlet ice warning- .025 inches of ice on the left engine probe. This ice cannot form in these conditions, therefore, no warning should appear. You can see this info on the NATOPS page referenced in page two of that post you linked. Thanks for the info.

SonofEil Posted January 14, 2019 Share Posted January 14, 2019 (edited) Considering DCS doesn’t simulate humidity or icing to begin with the inlet ice warning should've never been coded in the first place. At the very least it should’ve been disabled when it started popping up last summer. Edited January 14, 2019 by SonofEil i7 7700K @5.0, 1080Ti, 32GB DDR4, HMD Odyssey, TM WH, Crosswind Rudder...

I get your frustration, it's really annoying. Might I suggest that you do what I did? I inserted that item in my start up checklist: right after hook check, the manual makes you check the pitot heating (which shouldn't have any real effect right now). Well, I just turn on the pitot and the ice inlet heating and leave them active all the time. Problem solved. Now, if only there was a definitive solution to the Home fuel advisory....

Nooch Posted January 14, 2019 Share Posted January 14, 2019 Same thing with A-10C pitot freeze or Ka-50 rotor and engine ice. It has been discussed at length already. It will only go away when moisture simulation will have been implemented in the sim. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
Flamin_Squirrel Posted January 14, 2019 Share Posted January 14, 2019 Well, I just turn on the pitot and the ice inlet heating and leave them active all the time. Problem solved. I have to confess I've not tried, but IIRC, if that works, it shouldn't. The ice detection probe is located upstream of the fan and in turn the bleed air providing inlet anti-ice. In otherwords, the inlet heat doesn't heat the detector; therefore the inlet ice warning (should) only tell you when icing conditions exists, not that the engines have been sufficiently heated themselves. I hope that makes sense. You'll also get a performance penalty for having anti-ice on too. Now, if only there was a definitive solution to the Home fuel advisory.... You can change the Home waypoint to one closer to you, that might help. Link to comment Share on other sites More sharing options...
drallabco Posted January 14, 2019 Author Share Posted January 14, 2019 You'll also get a performance penalty for having anti-ice on too. Exactly. Anything that runs off the bleeds reduces engine power available because this pulls compressor air. This compressed air can then no longer be used in the combustor cans to combine with fuel and create power. Whether DCS models bleed air losses is something I'm not sure of, but until then, I'm gonna leave my engine heat off unless I'm actually flying in icing conditions.

Rainmaker Posted January 14, 2019 Share Posted January 14, 2019 Now, if only there was a definitive solution to the Home fuel advisory.... Haven’t flown anything in a while, but the last few times I did, I noticed that you could cycle the waypoint on the fuel page to one that is nonexistant in the flight plan and it would go away. With that being said, it would bug out and you could no longer cycle the steerpoint after that. Not sure if that still works or not as I’m a few beta releases behind.

Cake Posted January 16, 2019 Share Posted January 16, 2019 I agree that visible moisture should be present to cause inlet ice. The bigger point missed so far, at least in this thread, is that icing conditions for jets is based on RAT, not OAT. RAT increases with speed, so at temperatures slightly below zero outside air temperature, the RAT can be well above zero and icing should not occur in these conditions even with visible moisture. Clearly this is modeled incorrectly. Maybe the modeling just uses outside air temperature and doesn’t correct for this? 6700K@4.6 48Gb - 1080Ti Hybrid - Warthog - RIFT Link to comment Share on other sites More sharing options...
