  1. Morning all, I got a frozen pitot yesterday even though flying in clear sky and having Pitot Heat ON, so decided to investigate and reproduce it tounderstand why that bug happened on that particular flight. After quite extensive testing, I understand the module has a "severe icing" condition logic where in certain conditions, Pitot Heat will be overwhelmed and Pitot will freeze regardless of heating system being ON (Same for canopy loading Ice, but that does not bother me too much) ! This condition criteria is OAT between 0°C and -10°C (the closest to 0, the most severe) and precipitation being present. Cloud density/thickness and fog have no influence. Problem is it does not track if you are actualy flying in precipitation or cloud/fog whatsoever, the only criteria is "there is precipitation somewhere". So if you basically fly at 20000ft in clear sky with OAT -2°C, and there is down bealow a cloud layer toping at 3000ft generating rain, your Pitot freeze whatever you will do. Having such severe icing condition criteria might not be a bad idea, I don't know the real aircraft and maybe the Pitot heat system is weak. Problem is the way it is done in DCS makes it completely unrealistic right know as you just loose IAS when you should definitely not and with no way counteract it. I attach a track where reproduced. Happy landings ! Arnaud debug.trk
  2. Evening all, After doing a mission carrying 8x OFAB 100 High Drag bombs, I had a serious doubt on the drag model of the rack they are mounted on.. This rack is a MER-7 according to my research. To investigate, I experimented flying 3000ft in ISA conditions with 103% RPM and different config to measure speed at which stabalize. Here are the results : 4x MER-7 Rack + 8x OFAB100 = 230 kts 4x UB16 Rockets = 240 kts 4x MER-7 Rack = 250 kts 2x MER-7 + 4x OFAB100 = 280 kts 2x UB16 Rockets = 290 kts 2x MER-7 Rack = 295 kts 4x OFAB100 = 330 kts Clean = 350 kts According to DCS, MER-7 rack weights 103kg while OFAB100 is 120kg and Rocket pod 129kg. So we can approximate they are all the same and conclude the measured speed difference reflects exactly the drag coef difference. Conclusion of the above is that an MER-7 rack has almost the same drag coefficient than a rocket pod which does not make sense to me when you look their shapes (attached picture below). I know it's a lot of effort for few, but when you're painfuly doing 230 kts for your run where you should make around 280 ish, that starts to be a problem ! Happy landings !
  3. Thank you very much for your answer. Thats what I supposed but the 30 minutes screwed me because it appears a huge time potential for a "desperate extra power needed" !
  4. Hi all, I am curently learning this wonderfull module and ther is something I am not clearly understanding regarding max torque. I must confess I have limited knowledge on helicopter and that's might be why ! I read the manual, chuck's guide and even a real aircraft manual with no joy to understand. It basically says on the engine power limitation that max torque is 115% shown red on engine MFD page, and that anything above 100% should be transient and 6 sec limited (talking dual engine). Meanwhile, the MAX Q DE on perf page displays 30 minutes max torque and is usually well above 115%. What is the maximum torque at the end ? And what does this 6 sec limitation for transient means if you could afford 30 minutes above 115% ? Thank you for your clarifications ! Happy flights
