reported INS looses alignment following engine shutdown with EPU active - DCS World Open Beta 2.8.0.33006

[Posohm]

DCS World Open Beta 2.8.0.33006

Bug: If you loose engine - either by shutting it off, running out of fuel or whatever, and subsequently EPU activates - the INS looses alignment and you loose all inertial reference in the HUD ( ADI remains fine).

To reproduce:

1. Enter a turn ( e.g. 30° bank )

2. Set throttle to Idle detent to shut it off

3. Notice the EPU automatically activate.

4. Notice HUD ladder mis-align.

[ Expected result should be that INS integrity is maintained ]

An engine-out should not trigger a total INS failure.

Trackfile attached.

 

Example (old) hud video from the 80's showing an actual engine-out.

reported tot he team for checking

thanks

I recently encountered an issue within the game that I'd like to provide feedback on.

When the aircraft's engine flameout in mid-air, the INS loses power, resulting in drift in ADI and HUD symbology and flight path marker. However, this behavior doesn't seem to happen in real-world videos of flights.

This is a really old bug which has been reported many times before. The problem is that in the DCS F-16C the EPU does not power all the systems connected to the emergency buses. This is why the INS always looses power when you have a flameout in DCS but not in real life, because in DCS it is simply not powered by the EPU. No word on when this will be fixed.

+1 please fix ED

ED please address the EPU and associated electronic assets powered by the Emergency Bus when under EPU power. Thanks
