GumidekCZ Posted August 12, 2023 Share Posted August 12, 2023 (edited) High Tacan SOF.trkThe BUG here is that running EPU should support most of vital avionics and hydraulics (engine off). Buses Lost: 1) Non-essential DC 2) Essential DC (This results in loss of power to fuel boost and transfer pumps, CARA, ECM, and FCR and power for normal weapon arming/release including selective jettison.) Equipment Lost while running EPU: (REFS-REFS) R) Radar Altimeter (CARA) R) Recce Pod (236) E) ECM (184) E) EW CMS F) FCR F) Fuel Pumps (Boost/Transfer) S) SMS Arm/Release Power S) S-J Now in DCS, giro is completely off, no FMP, no navigation, no TACAN, just speed, BARO altimeter and radios. Which is in contradiction of what we can see in two popular real life examples of Engine off landing we can found on Youtube. Another BUG with EPU: According to EMERGENCY MANUAL, running JFS is increasing used Hydrazine. 8nm, 40% w JFS (45% w/o) 4nm, 20% w JFS (25% w/o) In DCS now, it doesnt matter, after same amount of time, EPU used same amount of hydrazine, with or w/o JFS running. And one another: according to EMER PROC guides, REDUCING CONTROL SURFACE MOTIONS WILL REDUCE USAGE OF HYDRAZINE. - NOT IN DCS.

WHOGX5 Posted August 14, 2023 Share Posted August 14, 2023 I see that this thread is marked with "pm evidence". You can simply open a -1 flight manual of your choosing and check the power distribution diagrammes. They will list everything that is powered by the EPU (and a lot of those items are currently not powered in DCS using the EPU). I'm sure ED has much more modern documentation in their possession than any of us have access to, which would naturally be more useful for the type of F-16C they're modelling. 7 -Col.

However, if it's coming for you, it doesn't make you feel too good, but it does rearrange your priorities."

Tango3B Posted August 14, 2023 Share Posted August 14, 2023 You ask for evidence on that system? Okay, then open up your -1 manual, go to section 1 and start reading from 1-98 thru to 1-104. These pages deal with the EPU. You also want to read the section before that starting from 1-82 thru to 1-97. That very section deals with the electrical system and said power distribution diagrammes in general. There you will find all the evidence needed and you will also see that GumidekCZ is absolutely right about the EPU. Thank you. 5 Link to comment Share on other sites More sharing options...
ED Team Lord Vader Posted August 17, 2023 ED Team Share Posted August 17, 2023 Hi @GumidekCZ We are aware the EPU isn't currently working as intended. We are still working on it, including Hydrazine consumption. We should consider these non-normal procedures as work in progress for now. Thank you for your patience. 2 1 Esquadra 701 - DCS Portugal - Discord Link to comment Share on other sites More sharing options...
