Revi Posted October 28, 2020 Share Posted October 28, 2020 Hey guys ran into a issue where my pitot (i assume) would freeze, which resulted in my speed indicator, climb indicator and altitude indicator being frozen, not functioning. Even though pitot heat was on. I am sure that it is not supposed to be like that, since a p47 would spend a huge amount of time in freezing temperature. As you can see in the picture below, by the horizon indicator you see i am climbing, but the climb indicator does not show it, also the speed is not correct (stuck in place on the gage) and the altitude indicator. When i dropped down to below freezing temperature, all would function again. So we concluded that it must have to do with the pitot heater not functioning. https://cdn.discordapp.com/attachmen...98/unknown.png To add, my speed indicator is still broken, shows 0, but i am going 320 kn. This is below freezing temperatures https://cdn.discordapp.com/attachmen...88/unknown.png I could try and replicate the issue, but atm it is in a DCS liberation campaign, which uses certain scripts that (from what i heard), would corrupt the tracks. If you still would like the track,here it is (use google drive, since the file is bigger then 5MB) https://drive.google.com/file/d/1vx6511HT84ivzBv1JUFeC-fUvfGHRGc-/view?usp=sharing Link to comment Share on other sites More sharing options...

Reflected Posted November 1, 2020 Share Posted November 1, 2020 Same here. Actually my ASI works fine, then drops to 0 when I descend below 1-2,000 feet. Facebook Instagram YouTube Discord Link to comment Share on other sites More sharing options...
ED Team BIGNEWY Posted November 2, 2020 ED Team Share Posted November 2, 2020 Thank you for the track Revi, sadly I think the scripted nature of the mission made it difficult to use in testing. I have not reproduce this issue myself if someone has a short track showing it please attach it. thank you Forum rules - DCS Crashing?

oreste Posted November 11, 2020 Share Posted November 11, 2020 I confirm that I have had problems with the speed indicator. I also thought about freezing or a high speed effect, it happened when I went down from 15000 ft. It also indicated the reverse speed, that is, going up in altitude it increased and down it decreased ... contrary to how it should be. In some cases it dropped to zero ft and then resumed working at very low altitudes.All this happened to me towards the end of a long journey, in fact I consumed an entire external tank and half of the internal fuel, almost all of the map from south to north. I would add that I did not subject the plane to particular efforts or acrobatics but I traveled all the way at a cruising speed, average altitudes between 10000 and 20,000. Air temperature in the carburetors always very low, the turbo rarely activated I traveled with the intercooler closed and oil cooling on neutral Obviously I checked several times if the pitot tube was activated, I admit that I only turned it on after a while I was in flight. I hope my testimony will be useful to you, good continuation. [sIGPIC][/sIGPIC]My dream: DCS Tornado Link to comment Share on other sites More sharing options...

The mechanical clocks technology I believe has been the same since before WW2. ASI, VSI, ALT, all three depends on air pressure changes. They all have in common a "static pressure" input that affects all three. If ED actually models a frozen static pressure input, that would be ambitious and interesting. If pitot froze it would only impact the ASI, not the VSI or ALT.

Erlkönig Posted April 24, 2021 Share Posted April 24, 2021 Hi, I just want to bump this thread; I do experience this error also in the BF-109 as well as the Mig 15 (not sure if I have to make separate threads, since it is the same error). It occurs to me only since the 2.7 update. Pitot heating simply does not seem to work anymore. Link to comment Share on other sites More sharing options...

Actually my ASI works fine, then drops to 0 when I descend below 1-2,000 feet. bump. Happened to me on the Wolf Pack mission 1. ATM actually - paused during my descent in formation to see if I was missing something. Formation flying/landing by feel is gonna be fun. EDIT: Came back on at around 200'. My pitot heat was on the whole flight, and I descended in formation. Need to read up on function, I guess, but would imagine that I was within accepted parameters for operation.

Zaremba Posted August 4, 2021 Share Posted August 4, 2021 Same problem here in P-47. Yesterday on Storm of War server, today on Aerobatic Europe Syria. Will save the track if it occure again. Link to comment Share on other sites More sharing options...
Jedrzej Posted November 25, 2022 Share Posted November 25, 2022 Hi. Is this problem solved? Today, on Channel Map my airspeed stops work above 17000 feet and do not to start. I've turned on the pitot heat. Link to comment Share on other sites More sharing options...
paura19 Posted December 7, 2022 Share Posted December 7, 2022 Jedrzel: I think not. Yesterday We flew on winter Channel map with -8°C and 7/8 pilots have issue with speed gauge.

Airspeed gauge becomes unreliable at 10 minutes in (fastest I could get it to occur). Remedied by returning to low altitude.

Nealius Posted December 17, 2022 Share Posted December 17, 2022 Should the probe even have icing at all if you don't fly into clouds? Link to comment Share on other sites More sharing options...

Either way, the pitot heat should work unless you burn it up by having it on when not flying. In the sim, the problem still occurs in clear, cold air, it just takes longer to show up. Hope this helps. Link to comment Share on other sites More sharing options...
