Justin Case Posted February 9, 2016 Posted February 9, 2016 (edited) Is the pitot tube really supposed to freeze in clear and dry air conditions at altitudes above 40 000 feet? Edit: This is with pitot heat on. Edited February 11, 2016 by Justin Case http://www.masterarms.se A Swedish Combat Flight Simulator Community.

1.JaVA_Platypus Posted February 11, 2016 Posted February 11, 2016 You mean were the air is minus 50 degrees Celsius? I thought Pitot heat is recommended whenever the temperature is near or below the freezingpoint. And is the airhumidity even modelled in DCS? Happy Flying! :pilotfly:
1.JaVA_Platypus Posted February 11, 2016 Posted February 11, 2016 My point is, how do you know the air is dry? Happy Flying! :pilotfly:
Justin Case Posted February 11, 2016 Author Posted February 11, 2016 BTW I forgot to mention that the pitot heat was on from start up. :doh: My point is, how do you know the air is dry? Because the air is clear, no condensation has occurred. You will generally not encounter icing at such high altitudes unless there are storm cells near by, like AF447, and as far as I know we dont have storm cells of that magnitude in DCS. http://www.masterarms.se A Swedish Combat Flight Simulator Community.
SimFreak Posted February 12, 2016 Posted February 12, 2016 For how long do you have to hover above 40k to experience this?
Justin Case Posted February 12, 2016 Author Posted February 12, 2016 (edited) Often it's instant, though once I made it up to 15000 m and down to 12 000 before it froze. Edited February 12, 2016 by Justin Case http://www.masterarms.se A Swedish Combat Flight Simulator Community.
SimFreak Posted February 15, 2016 Posted February 15, 2016 Bug has been submitted. Thanks. (ref: 0033656)
Justin Case Posted February 15, 2016 Author Posted February 15, 2016 Great! :thumbup: I'm looking forward to diving down on unsuspecting Sabres. http://www.masterarms.se A Swedish Combat Flight Simulator Community.
Justin Case Posted February 16, 2016 Author Posted February 16, 2016 How about a joke on the subject? Why does the MiG-15 wear socks? Because otherwise he would freeze his pi-toes of... http://www.masterarms.se A Swedish Combat Flight Simulator Community.
CoverNow Posted February 16, 2016 Posted February 16, 2016 There MUST be moisture in the air for the pitot tube to ice over. General for us, its visable moisture (clouds), and temperature less than 10 degrees C. Humidity (and i could be corrected) on this shouldnt be able to cause pitot icong (people often think that it would because it can cause carb or induction icing). But the pitot tube does not have a venturi (look up bernullis principle if your curious) so the principles are different. As air temperature decreases to near freezing, the amount of moisture in the air also decreases. So at altitudes where the temperature is at or below freezing, there is often very little if any humidity or moisture. Exceptions can occur based upon the dew point (point at which moisture will condense), where clouds form in sometimes below freezing levels. Side note, avoid turning off pitot heat in any conditions not expected to cause icing, otherwise you risk buring out the pitot-heat (although im not sure if this is modled) Cheers!
