Afterburner issues: uneven appearance, delayed and excessively asymmetric staging rates


Recommended Posts

Posted

Would you guys be willing to take a look at the current AB behavior? This is coming from someone who only flies the A, but I remember the B having similar issues. My basis for concern is coming from having sat through hours upon hours of footage of the Tomcat A- and my 3 concerns are thus:

 

Afterburners may be staging too slowly. I have seen many videos where the aircraft goes from zone 1 lightoff to zone 5 in under 4 seconds, whereas the DCS Tomcat I have seen take upwards of 6 seconds to stage both engines to zone 5.

 

Afterburners are also staging asymmetrically with exaggerated delays between engines (I have even seen that one engine can stage twice before the opposing engine advances a stage). Most of the footage I have seen shows the staging occurring between engines almost simultaneously with any delay being almost imperceptible. (this is not a technique item, I have tried binding both engines to the same axis, same result)

 

Last issue is that afterburners sometimes will present uneven plumes. I don't know if that was intentional or not. I have actually seen a video where one engine appears brighter than the other, but most of the time they are evenly balanced.

Yes, all of those are correct. Finally we have engines that do not behave like quantum entangled twins. Thank god Heatblur for that.

We have no plans to change anything about the afterburner on the simulation side. The amount of time each takes to light is dependent on various conditions such as airspeed, altitude and various engine states.

SME input is great and all but how do we explain all of the video footage of wet cat shots where the engines are staging almost simultaneously and at a faster rate than what is modeled in the sim?

We go with SME input whenever possible, there are no plans to change it at this time. There are several videos out there showing that full Zone 5 light-off takes at least 5 seconds, in some situation much more, and the time it takes between engines can vary quite a bit.

Not sure why my videos are posted, other than to remind me of my terrible rudder coordination on the clearing turns. Those were all Bravo shots at MIL power.
